|
||||
|
||||
## Usage guide
|
||||
|
||||
### Initializing the sensor
|
||||
|
||||
To initialize the sensor, you will first need to create a device structure. You
|
||||
can do this by creating an instance of the structure bme680_dev. Then go on to
|
||||
fill in the various parameters as shown below
|
||||
|
||||
#### Example for SPI 4-Wire
|
||||
|
||||
``` c
|
||||
struct bme680_dev gas_sensor;
|
||||
|
||||
/* You may assign a chip select identifier to be handled later */
|
||||
gas_sensor.dev_id = 0;
|
||||
gas_sensor.intf = BME680_SPI_INTF;
|
||||
gas_sensor.read = user_spi_read;
|
||||
gas_sensor.write = user_spi_write;
|
||||
gas_sensor.delay_ms = user_delay_ms;
|
||||
/* amb_temp can be set to 25 prior to configuring the gas sensor
|
||||
* or by performing a few temperature readings without operating the gas sensor.
|
||||
*/
|
||||
gas_sensor.amb_temp = 25;
|
||||
|
||||
int8_t rslt = BME680_OK;
|
||||
rslt = bme680_init(&gas_sensor);
|
||||
```
|
||||
|
||||
#### Example for I2C
|
||||
|
||||
``` c
|
||||
struct bme680_dev gas_sensor;
|
||||
|
||||
gas_sensor.dev_id = BME680_I2C_ADDR_PRIMARY;
|
||||
gas_sensor.intf = BME680_I2C_INTF;
|
||||
gas_sensor.read = i2c_read;
|
||||
gas_sensor.write = i2c_write;
|
||||
gas_sensor.delay_ms = user_delay_ms;
|
||||
/* amb_temp can be set to 25 prior to configuring the gas sensor
|
||||
* or by performing a few temperature readings without operating the gas sensor.
|
||||
*/
|
||||
gas_sensor.amb_temp = 25;
|
||||
|
||||
|
||||
int8_t rslt = BME680_OK;
|
||||
rslt = bme680_init(&gas_sensor);
|
||||
```
|
||||
|
||||
Regarding compensation functions for temperature, pressure, humidity and gas we have two implementations.
|
||||
|
||||
- Integer version
|
||||
- floating point version
|
||||
|
||||
By default, Integer version is used in the API
|
||||
|
||||
If the user needs the floating point version, the user has to un-comment BME680_FLOAT_POINT_COMPENSATION macro
|
||||
in bme680_defs.h file or to add it in the compiler flags.
|
||||
|
||||
### Configuring the sensor
|
||||
|
||||
#### Example for configuring the sensor in forced mode
|
||||
|
||||
``` c
|
||||
uint8_t set_required_settings;
|
||||
|
||||
/* Set the temperature, pressure and humidity settings */
|
||||
gas_sensor.tph_sett.os_hum = BME680_OS_2X;
|
||||
gas_sensor.tph_sett.os_pres = BME680_OS_4X;
|
||||
gas_sensor.tph_sett.os_temp = BME680_OS_8X;
|
||||
gas_sensor.tph_sett.filter = BME680_FILTER_SIZE_3;
|
||||
|
||||
/* Set the remaining gas sensor settings and link the heating profile */
|
||||
gas_sensor.gas_sett.run_gas = BME680_ENABLE_GAS_MEAS;
|
||||
/* Create a ramp heat waveform in 3 steps */
|
||||
gas_sensor.gas_sett.heatr_temp = 320; /* degree Celsius */
|
||||
gas_sensor.gas_sett.heatr_dur = 150; /* milliseconds */
|
||||
|
||||
/* Select the power mode */
|
||||
/* Must be set before writing the sensor configuration */
|
||||
gas_sensor.power_mode = BME680_FORCED_MODE;
|
||||
|
||||
/* Set the required sensor settings needed */
|
||||
set_required_settings = BME680_OST_SEL | BME680_OSP_SEL | BME680_OSH_SEL | BME680_FILTER_SEL
|
||||
| BME680_GAS_SENSOR_SEL;
|
||||
|
||||
/* Set the desired sensor configuration */
|
||||
rslt = bme680_set_sensor_settings(set_required_settings,&gas_sensor);
|
||||
|
||||
/* Set the power mode */
|
||||
rslt = bme680_set_sensor_mode(&gas_sensor);
|
||||
|
||||
|
||||
```
|
||||
|
||||
### Reading sensor data
|
||||
|
||||
#### Example for reading all sensor data
|
||||
|
||||
``` c
|
||||
/* Get the total measurement duration so as to sleep or wait till the
|
||||
* measurement is complete */
|
||||
uint16_t meas_period;
|
||||
bme680_get_profile_dur(&meas_period, &gas_sensor);
|
||||
|
||||
struct bme680_field_data data;
|
||||
|
||||
while(1)
|
||||
{
|
||||
user_delay_ms(meas_period); /* Delay till the measurement is ready */
|
||||
|
||||
rslt = bme680_get_sensor_data(&data, &gas_sensor);
|
||||
|
||||
printf("T: %.2f degC, P: %.2f hPa, H %.2f %%rH ", data.temperature / 100.0f,
|
||||
data.pressure / 100.0f, data.humidity / 1000.0f );
|
||||
/* Avoid using measurements from an unstable heating setup */
|
||||
if(data.status & BME680_GASM_VALID_MSK)
|
||||
printf(", G: %d ohms", data.gas_resistance);
|
||||
|
||||
printf("\r\n");
|
||||
|
||||
/* Trigger the next measurement if you would like to read data out continuously */
|
||||
if (gas_sensor.power_mode == BME680_FORCED_MODE) {
|
||||
rslt = bme680_set_sensor_mode(&gas_sensor);
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Templates for function pointers
|
||||
|
||||
``` c
|
||||
|
||||
void user_delay_ms(uint32_t period)
|
||||
{
|
||||
/*
|
||||
* Return control or wait,
|
||||
* for a period amount of milliseconds
|
||||
*/
|

|
||||
* to be set low to activate the relevant device on the SPI bus
|
||||

|
||||
* ### Interface usage
|
||||
*
|
||||
* The following provides a short overview on the typical operation sequence for BSEC.
|
||||
*
|
||||
* - Initialization of the library
|
||||
*
|
||||
* | Steps | Function |
|
||||
* |---------------------------------------------------------------------|--------------------------|
|
||||
* | Initialization of library | bsec_init() |
|
||||
* | Update configuration settings (optional) | bsec_set_configuration() |
|
||||
* | Restore the state of the library (optional) | bsec_set_state() |
|
||||
*
|
||||
*
|
||||
* - The following function is called to enable output signals and define their sampling rate / operation mode.
|
||||
*
|
||||
* | Steps | Function |
|
||||
* |---------------------------------------------|----------------------------|
|
||||
* | Enable library outputs with specified mode | bsec_update_subscription() |
|
||||
*
|
||||
*
|
||||
* - This table describes the main processing loop.
|
||||
*
|
||||
* | Steps | Function |
|
||||
* |-------------------------------------------|----------------------------------|
|
||||
* | Retrieve sensor settings to be used | bsec_sensor_control() |
|
||||
* | Configure sensor and trigger measurement | See BME680 API and example codes |
|
||||
* | Read results from sensor | See BME680 API and example codes |
|
||||
* | Perform signal processing | bsec_do_steps() |
|
||||
*
|
||||
*
|
||||
* - Before shutting down the system, the current state of BSEC can be retrieved and can then be used during
|
||||
* re-initialization to continue processing.
|
||||
*
|
||||
* | Steps | Function |
|
||||
* |----------------------------------------|-------------------|
|
||||
* | To retrieve the current library state | bsec_get_state() |
|
||||
*
|
||||
*
|
||||
*
|
||||
* ### Configuration and state
|
||||
*
|
||||
* Values of variables belonging to a BSEC instance are divided into two groups:
|
||||
* - Values **not updated by processing** of signals belong to the **configuration group**. If available, BSEC can be
|
||||
* configured before use with a customer specific configuration string.
|
||||
* - Values **updated during processing** are member of the **state group**. Saving and restoring of the state of BSEC
|
||||
* is necessary to maintain previously estimated sensor models and baseline information which is important for best
|
||||
* performance of the gas sensor outputs.
|
||||
*
|
||||
* @note BSEC library consists of adaptive algorithms which models the gas sensor which improves its performance over
|
||||
* the time. These will be lost if library is initialized due to system reset. In order to avoid this situation
|
||||
* library state shall be stored in non volatile memory so that it can be loaded after system reset.

* @brief Subscribe to library virtual sensors outputs
|

*
|

* Use bsec_update_subscription() to instruct BSEC which of the processed output signals are requested at which sample rates.
|
||||
* See ::bsec_virtual_sensor_t for available library outputs.
|
||||
*
|
||||
* Based on the requested virtual sensors outputs, BSEC will provide information about the required physical sensor input signals
|
||||
* (see ::bsec_physical_sensor_t) with corresponding sample rates. This information is purely informational as bsec_sensor_control()
|
||||
* will ensure the sensor is operated in the required manner. To disable a virtual sensor, set the sample rate to BSEC_SAMPLE_RATE_DISABLED.
|
||||
*
|
||||
* The subscription update using bsec_update_subscription() is apart from the signal processing one of the the most
|
||||
* important functions. It allows to enable the desired library outputs. The function determines which physical input
|
||||
* sensor signals are required at which sample rate to produce the virtual output sensor signals requested by the user.
|
||||
* When this function returns with success, the requested outputs are called subscribed. A very important feature is the
|
||||
* retaining of already subscribed outputs. Further outputs can be requested or disabled both individually and
|
||||
* group-wise in addition to already subscribed outputs without changing them unless a change of already subscribed
|
||||
* outputs is requested.
|
||||
*
|
||||
* @note The state of the library concerning the subscribed outputs cannot be retained among reboots.
|
||||
*
|
||||
* The interface of bsec_update_subscription() requires the usage of arrays of sensor configuration structures.
|
||||
* Such a structure has the fields sensor identifier and sample rate. These fields have the properties:
|
||||
* - Output signals of virtual sensors must be requested using unique identifiers (Member of ::bsec_virtual_sensor_t)
|
||||
* - Different sets of identifiers are available for inputs of physical sensors and outputs of virtual sensors
|
||||
* - Identifiers are unique values defined by the library, not from external
|
||||
* - Sample rates must be provided as value of
|
||||
* - An allowed sample rate for continuously sampled signals
|
||||
* - 65535.0f (BSEC_SAMPLE_RATE_DISABLED) to turn off outputs and identify disabled inputs
|
||||
*
|
||||
* @note The same sensor identifiers are also used within the functions bsec_do_steps().
|
||||
*
|
||||
* The usage principles of bsec_update_subscription() are:
|
||||
* - Differential updates (i.e., only asking for outputs that the user would like to change) is supported.
|
||||
* - Invalid requests of outputs are ignored. Also if one of the requested outputs is unavailable, all the requests
|
||||
* are ignored. At the same time, a warning is returned.
|
||||
* - To disable BSEC, all outputs shall be turned off. Only enabled (subscribed) outputs have to be disabled while
|
||||

* within the same time period as they are read. A sequential provision to the library might result in undefined

* behavior.
|
||||
* - The samples of all library outputs are returned with unique identifiers corresponding to the output signals of
|
||||
* virtual sensors where the order of the returned outputs may be arbitrary.
|
||||
* - The samples of all input as well as output signals of physical as well as virtual sensors use the same
|
||||
* representation in memory with the following fields:
|
||||
* - Sensor identifier:
|
||||
* - For inputs: required to identify the input signal from a physical sensor
|
||||
* - For output: overwritten by bsec_do_steps() to identify the returned signal from a virtual sensor
|
||||
* - Time stamp of the sample
|
||||
*
|
||||
* Calling bsec_do_steps() requires the samples of the input signals to be provided along with their time stamp when
|
||||
* they are recorded and only when they are acquired. Repetition of samples with the same time stamp are ignored and
|
||||
* result in a warning. Repetition of values of samples which are not acquired anew by a sensor result in deviations
|

* of the computed output signals. Concerning the returned output samples, an important feature is, that a value is

||||
|
||||
The licenses for most software are designed to take away your
|
||||
freedom to share and change it. By contrast, the GNU General Public
|
||||
Licenses are intended to guarantee your freedom to share and change
|
||||
free software--to make sure the software is free for all its users.
|
||||
|
||||
This license, the Lesser General Public License, applies to some
|
||||
specially designated software packages--typically libraries--of the
|
||||
Free Software Foundation and other authors who decide to use it. You
|
||||
can use it too, but we suggest you first think carefully about whether
|
||||
this license or the ordinary General Public License is the better
|
||||
strategy to use in any particular case, based on the explanations below.
|
||||
|
||||
When we speak of free software, we are referring to freedom of use,
|
||||
not price. Our General Public Licenses are designed to make sure that
|
||||
you have the freedom to distribute copies of free software (and charge
|
||||
for this service if you wish); that you receive source code or can get
|
||||
it if you want it; that you can change the software and use pieces of
|
||||
it in new free programs; and that you are informed that you can do
|
||||
these things.
|
||||
|
||||
To protect your rights, we need to make restrictions that forbid
|
||||
distributors to deny you these rights or to ask you to surrender these
|
||||
rights. These restrictions translate to certain responsibilities for
|
||||
you if you distribute copies of the library or if you modify it.
|
||||
|
||||
For example, if you distribute copies of the library, whether gratis
|
||||
or for a fee, you must give the recipients all the rights that we gave
|
||||
you. You must make sure that they, too, receive or can get the source
|
||||
code. If you link other code with the library, you must provide
|
||||
complete object files to the recipients, so that they can relink them
|
||||
with the library after making changes to the library and recompiling
|
||||
it. And you must show them these terms so they know their rights.
|
||||
|
||||
We protect your rights with a two-step method: (1) we copyright the
|
||||
library, and (2) we offer you this license, which gives you legal
|
||||
permission to copy, distribute and/or modify the library.
|
||||
|
||||
To protect each distributor, we want to make it very clear that
|
||||
there is no warranty for the free library. Also, if the library is
|
||||
modified by someone else and passed on, the recipients should know
|
||||
that what they have is not the original version, so that the original
|
||||
author's reputation will not be affected by problems that might be
|
||||
introduced by others.
|
||||
|
||||
Finally, software patents pose a constant threat to the existence of
|
||||
any free program. We wish to make sure that a company cannot
|
||||
effectively restrict the users of a free program by obtaining a
|
||||
restrictive license from a patent holder. Therefore, we insist that
|
||||
any patent license obtained for a version of the library must be
|
||||
consistent with the full freedom of use specified in this license.
|
||||
|
||||
Most GNU software, including some libraries, is covered by the
|
||||
ordinary GNU General Public License. This license, the GNU Lesser
|
||||
General Public License, applies to certain designated libraries, and
|
||||
is quite different from the ordinary General Public License. We use
|
||||
this license for certain libraries in order to permit linking those
|
||||
libraries into non-free programs.
|
||||
|
||||
When a program is linked with a library, whether statically or using
|
||||
a shared library, the combination of the two is legally speaking a
|
||||
combined work, a derivative of the original library. The ordinary
|
||||
General Public License therefore permits such linking only if the
|
||||
entire combination fits its criteria of freedom. The Lesser General
|
||||
Public License permits more lax criteria for linking other code with
|
||||
the library.
|
||||
|
||||
We call this license the "Lesser" General Public License because it
|
||||
does Less to protect the user's freedom than the ordinary General
|
||||
Public License. It also provides other free software developers Less
|
||||
of an advantage over competing non-free programs. These disadvantages
|
||||
are the reason we use the ordinary General Public License for many
|
||||
libraries. However, the Lesser license provides advantages in certain
|
||||
special circumstances.
|
||||
|
||||
For example, on rare occasions, there may be a special need to
|
||||
encourage the widest possible use of a certain library, so that it becomes
|
||||
a de-facto standard. To achieve this, non-free programs must be
|
||||
allowed to use the library. A more frequent case is that a free
|
||||
library does the same job as widely used non-free libraries. In this
|
||||
case, there is little to gain by limiting the free library to free
|
||||
software only, so we use the Lesser General Public License.
|
||||
|
||||
In other cases, permission to use a particular library in non-free
|
||||
programs enables a greater number of people to use a large body of
|
||||
free software. For example, permission to use the GNU C Library in
|
||||
non-free programs enables many more people to use the whole GNU
|
||||
operating system, as well as its variant, the GNU/Linux operating
|
||||
system.
|
||||
|
||||
Although the Lesser General Public License is Less protective of the
|
||||
users' freedom, it does ensure that the user of a program that is
|
||||
linked with the Library has the freedom and the wherewithal to run
|
||||
that program using a modified version of the Library.
|
||||
|
||||
The precise terms and conditions for copying, distribution and
|
||||
modification follow. Pay close attention to the difference between a
|
||||
"work based on the library" and a "work that uses the library". The
|
||||
former contains code derived from the library, whereas the latter must
|
||||
be combined with the library in order to run.
|
||||
|
||||
GNU LESSER GENERAL PUBLIC LICENSE
|
||||
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
|
||||
|
||||
0. This License Agreement applies to any software library or other
|
||||
program which contains a notice placed by the copyright holder or
|
||||
other authorized party saying it may be distributed under the terms of
|
||||
this Lesser General Public License (also called "this License").
|
||||
Each licensee is addressed as "you".
|
||||
|
||||
A "library" means a collection of software functions and/or data
|
||||
prepared so as to be conveniently linked with application programs
|
||||
(which use some of those functions and data) to form executables.
|
||||
|
||||
The "Library", below, refers to any such software library or work
|
||||
which has been distributed under these terms. A "work based on the
|
||||
Library" means either the Library or any derivative work under
|
||||
copyright law: that is to say, a work containing the Library or a
|
||||
portion of it, either verbatim or with modifications and/or translated
|
||||
straightforwardly into another language. (Hereinafter, translation is
|
||||
included without limitation in the term "modification".)
|
||||
|
||||
"Source code" for a work means the preferred form of the work for
|
||||
making modifications to it. For a library, complete source code means
|
||||
all the source code for all modules it contains, plus any associated
|
||||
interface definition files, plus the scripts used to control compilation
|
||||
and installation of the library.
|
||||
|
||||
Activities other than copying, distribution and modification are not
|
||||
covered by this License; they are outside its scope. The act of
|
||||
running a program using the Library is not restricted, and output from
|
||||
such a program is covered only if its contents constitute a work based
|
||||
on the Library (independent of the use of the Library in a tool for
|
||||
writing it). Whether that is true depends on what the Library does
|
||||
and what the program that uses the Library does.
|
||||
|
||||
1. You may copy and distribute verbatim copies of the Library's
|
||||
complete source code as you receive it, in any medium, provided that
|
||||
you conspicuously and appropriately publish on each copy an
|
||||
appropriate copyright notice and disclaimer of warranty; keep intact
|
||||
all the notices that refer to this License and to the absence of any
|
||||
warranty; and distribute a copy of this License along with the
|
||||
Library.
|
||||
|
||||
You may charge a fee for the physical act of transferring a copy,
|
||||
and you may at your option offer warranty protection in exchange for a
|
||||
fee.
|
||||
|
||||
2. You may modify your copy or copies of the Library or any portion
|
||||
of it, thus forming a work based on the Library, and copy and
|
||||
distribute such modifications or work under the terms of Section 1
|
||||
above, provided that you also meet all of these conditions:
|
||||
|
||||
a) The modified work must itself be a software library.
|
||||
|
||||
b) You must cause the files modified to carry prominent notices
|
||||
stating that you changed the files and the date of any change.
|
||||
|
||||
c) You must cause the whole of the work to be licensed at no
|
||||
charge to all third parties under the terms of this License.
|
||||
|
||||
d) If a facility in the modified Library refers to a function or a
|
||||
table of data to be supplied by an application program that uses
|
||||
the facility, other than as an argument passed when the facility
|
||||
is invoked, then you must make a good faith effort to ensure that,
|
||||
in the event an application does not supply such function or
|
||||
table, the facility still operates, and performs whatever part of
|
||||
its purpose remains meaningful.
|
||||
|
||||
(For example, a function in a library to compute square roots has
|
||||
a purpose that is entirely well-defined independent of the
|
||||
application. Therefore, Subsection 2d requires that any
|
||||
application-supplied function or table used by this function must
|
||||
be optional: if the application does not supply it, the square
|
||||
root function must still compute square roots.)
|
||||
|
||||
These requirements apply to the modified work as a whole. If
|
||||
identifiable sections of that work are not derived from the Library,
|
||||
and can be reasonably considered independent and separate works in
|
||||
themselves, then this License, and its terms, do not apply to those
|
||||
sections when you distribute them as separate works. But when you
|
||||
distribute the same sections as part of a whole which is a work based
|
||||
on the Library, the distribution of the whole must be on the terms of
|
||||
this License, whose permissions for other licensees extend to the
|
||||
entire whole, and thus to each and every part regardless of who wrote
|
||||
it.
|
||||
|
||||
Thus, it is not the intent of this section to claim rights or contest
|
||||
your rights to work written entirely by you; rather, the intent is to
|
||||
exercise the right to control the distribution of derivative or
|
||||
collective works based on the Library.
|
||||
|
||||
In addition, mere aggregation of another work not based on the Library
|
||||
with the Library (or with a work based on the Library) on a volume of
|
||||
a storage or distribution medium does not bring the other work under
|
||||
the scope of this License.
|
||||
|
||||
3. You may opt to apply the terms of the ordinary GNU General Public
|
||||
License instead of this License to a given copy of the Library. To do
|
||||
this, you must alter all the notices that refer to this License, so
|
||||
that they refer to the ordinary GNU General Public License, version 2,
|
||||
instead of to this License. (If a newer version than version 2 of the
|
||||
ordinary GNU General Public License has appeared, then you can specify
|
||||
that version instead if you wish.) Do not make any other change in
|
||||
these notices.
|
||||
|
||||
Once this change is made in a given copy, it is irreversible for
|
||||
that copy, so the ordinary GNU General Public License applies to all
|
||||
subsequent copies and derivative works made from that copy.
|
||||
|
||||
This option is useful when you wish to copy part of the code of
|
||||
the Library into a program that is not a library.
|
||||
|
||||
4. You may copy and distribute the Library (or a portion or
|
||||
derivative of it, under Section 2) in object code or executable form
|
||||
under the terms of Sections 1 and 2 above provided that you accompany
|
||||
it with the complete corresponding machine-readable source code, which
|
||||
must be distributed under the terms of Sections 1 and 2 above on a
|
||||
medium customarily used for software interchange.
|
||||
|
||||
If distribution of object code is made by offering access to copy
|
||||
from a designated place, then offering equivalent access to copy the
|
||||
source code from the same place satisfies the requirement to
|
||||
distribute the source code, even though third parties are not
|
||||
compelled to copy the source along with the object code.
|
||||
|
||||
5. A program that contains no derivative of any portion of the
|
||||
Library, but is designed to work with the Library by being compiled or
|
||||
linked with it, is called a "work that uses the Library". Such a
|
||||
work, in isolation, is not a derivative work of the Library, and
|
||||
therefore falls outside the scope of this License.
|
||||
|
||||
However, linking a "work that uses the Library" with the Library
|
||||
creates an executable that is a derivative of the Library (because it
|
||||
contains portions of the Library), rather than a "work that uses the
|
||||
library". The executable is therefore covered by this License.
|
||||
Section 6 states terms for distribution of such executables.
|
||||
|
||||
When a "work that uses the Library" uses material from a header file
|
||||
that is part of the Library, the object code for the work may be a
|
||||
derivative work of the Library even though the source code is not.
|
||||
Whether this is true is especially significant if the work can be
|
||||
linked without the Library, or if the work is itself a library. The
|
||||
threshold for this to be true is not precisely defined by law.
|
||||
|
||||
If such an object file uses only numerical parameters, data
|
||||
structure layouts and accessors, and small macros and small inline
|
||||
functions (ten lines or less in length), then the use of the object
|
||||
file is unrestricted, regardless of whether it is legally a derivative
|
||||
work. (Executables containing this object code plus portions of the
|
||||
Library will still fall under Section 6.)
|
||||
|
||||
Otherwise, if the work is a derivative of the Library, you may
|
||||
distribute the object code for the work under the terms of Section 6.
|
||||
Any executables containing that work also fall under Section 6,
|
||||
whether or not they are linked directly with the Library itself.
|
||||
|
||||
6. As an exception to the Sections above, you may also combine or
|
||||
link a "work that uses the Library" with the Library to produce a
|
||||
work containing portions of the Library, and distribute that work
|
||||
under terms of your choice, provided that the terms permit
|
||||
modification of the work for the customer's own use and reverse
|
||||
engineering for debugging such modifications.
|
||||
|
||||
You must give prominent notice with each copy of the work that the
|
||||
Library is used in it and that the Library and its use are covered by
|
||||
this License. You must supply a copy of this License. If the work
|
||||
during execution displays copyright notices, you must include the
|
||||
copyright notice for the Library among them, as well as a reference
|
||||
directing the user to the copy of this License. Also, you must do one
|
||||
of these things:
|
||||
|
||||
a) Accompany the work with the complete corresponding
|
||||
machine-readable source code for the Library including whatever
|
||||
changes were used in the work (which must be distributed under
|
||||
Sections 1 and 2 above); and, if the work is an executable linked
|
||||
with the Library, with the complete machine-readable "work that
|
||||
uses the Library", as object code and/or source code, so that the
|
||||
user can modify the Library and then relink to produce a modified
|
||||
executable containing the modified Library. (It is understood
|
||||
that the user who changes the contents of definitions files in the
|
||||
Library will not necessarily be able to recompile the application
|
||||
to use the modified definitions.)
|
||||
|
||||
b) Use a suitable shared library mechanism for linking with the
|
||||
Library. A suitable mechanism is one that (1) uses at run time a
|
||||
copy of the library already present on the user's computer system,
|
||||
rather than copying library functions into the executable, and (2)
|
||||
will operate properly with a modified version of the library, if
|
||||
the user installs one, as long as the modified version is
|
||||
interface-compatible with the version that the work was made with.
|
||||
|
||||
c) Accompany the work with a written offer, valid for at
|
||||
least three years, to give the same user the materials
|
||||
specified in Subsection 6a, above, for a charge no more
|
||||
than the cost of performing this distribution.
|
||||
|
||||
d) If distribution of the work is made by offering access to copy
|
||||
from a designated place, offer equivalent access to copy the above
|
||||
specified materials from the same place.
|
||||
|
||||
e) Verify that the user has already received a copy of these
|
||||
materials or that you have already sent this user a copy.
|
||||
|
||||
For an executable, the required form of the "work that uses the
|
||||
Library" must include any data and utility programs needed for
|
||||
reproducing the executable from it. However, as a special exception,
|
||||
the materials to be distributed need not include anything that is
|
||||
normally distributed (in either source or binary form) with the major
|
||||
components (compiler, kernel, and so on) of the operating system on
|
||||
which the executable runs, unless that component itself accompanies
|
||||
the executable.
|
||||
|
||||
It may happen that this requirement contradicts the license
|
||||
restrictions of other proprietary libraries that do not normally
|
||||
accompany the operating system. Such a contradiction means you cannot
|
||||
use both them and the Library together in an executable that you
|
||||
distribute.
|
||||
|
||||
7. You may place library facilities that are a work based on the
|
||||
Library side-by-side in a single library together with other library
|
||||
facilities not covered by this License, and distribute such a combined
|
||||
library, provided that the separate distribution of the work based on
|
||||
the Library and of the other library facilities is otherwise
|
||||
permitted, and provided that you do these two things:
|
||||
|
||||
a) Accompany the combined library with a copy of the same work
|
||||
based on the Library, uncombined with any other library
|
||||
facilities. This must be distributed under the terms of the
|
||||
Sections above.
|
||||
|
||||
b) Give prominent notice with the combined library of the fact
|
||||
that part of it is a work based on the Library, and explaining
|
||||
where to find the accompanying uncombined form of the same work.
|
||||
|
||||
8. You may not copy, modify, sublicense, link with, or distribute
|
||||
the Library except as expressly provided under this License. Any
|
||||
attempt otherwise to copy, modify, sublicense, link with, or
|
||||
distribute the Library is void, and will automatically terminate your
|
||||
rights under this License. However, parties who have received copies,
|
||||
or rights, from you under this License will not have their licenses
|
||||
terminated so long as such parties remain in full compliance.
|
||||
|
||||
9. You are not required to accept this License, since you have not
|
||||
signed it. However, nothing else grants you permission to modify or
|
||||
distribute the Library or its derivative works. These actions are
|
||||
prohibited by law if you do not accept this License. Therefore, by
|
||||
modifying or distributing the Library (or any work based on the
|
||||
Library), you indicate your acceptance of this License to do so, and
|
||||
all its terms and conditions for copying, distributing or modifying
|
||||
the Library or works based on it.
|
||||
|
||||
10. Each time you redistribute the Library (or any work based on the
|
||||
Library), the recipient automatically receives a license from the
|
||||
original licensor to copy, distribute, link with or modify the Library
|
||||
subject to these terms and conditions. You may not impose any further
|
||||
restrictions on the recipients' exercise of the rights granted herein.
|
||||
You are not responsible for enforcing compliance by third parties with
|
||||
this License.
|
||||
|
||||
11. If, as a consequence of a court judgment or allegation of patent
|
||||
infringement or for any other reason (not limited to patent issues),
|
||||
conditions are imposed on you (whether by court order, agreement or
|
||||
otherwise) that contradict the conditions of this License, they do not
|
||||
excuse you from the conditions of this License. If you cannot
|
||||
distribute so as to satisfy simultaneously your obligations under this
|
||||
License and any other pertinent obligations, then as a consequence you
|
||||
may not distribute the Library at all. For example, if a patent
|
||||
license would not permit royalty-free redistribution of the Library by
|
||||
all those who receive copies directly or indirectly through you, then
|
||||
the only way you could satisfy both it and this License would be to
|
||||
refrain entirely from distribution of the Library.
|
||||
|
||||
If any portion of this section is held invalid or unenforceable under any
|
||||
particular circumstance, the balance of the section is intended to apply,
|
||||
and the section as a whole is intended to apply in other circumstances.
|
||||
|
||||
It is not the purpose of this section to induce you to infringe any
|
||||
patents or other property right claims or to contest validity of any
|
||||
such claims; this section has the sole purpose of protecting the
|
||||
integrity of the free software distribution system which is
|
||||
implemented by public license practices. Many people have made
|
||||
generous contributions to the wide range of software distributed
|
||||
through that system in reliance on consistent application of that
|
||||
system; it is up to the author/donor to decide if he or she is willing
|
||||
to distribute software through any other system and a licensee cannot
|
||||
impose that choice.
|
||||
|
||||
This section is intended to make thoroughly clear what is believed to
|
||||
be a consequence of the rest of this License.
|
||||
|
||||
12. If the distribution and/or use of the Library is restricted in
|
||||
certain countries either by patents or by copyrighted interfaces, the
|
||||
original copyright holder who places the Library under this License may add
|
||||
an explicit geographical distribution limitation excluding those countries,
|
||||
so that distribution is permitted only in or among countries not thus
|
||||
excluded. In such case, this License incorporates the limitation as if
|
||||
written in the body of this License.
|
||||
|
||||
13. The Free Software Foundation may publish revised and/or new
|
||||
versions of the Lesser General Public License from time to time.
|
||||
Such new versions will be similar in spirit to the present version,
|
||||
but may differ in detail to address new problems or concerns.
|
||||
|
||||
Each version is given a distinguishing version number. If the Library
|
||||
specifies a version number of this License which applies to it and
|
||||
"any later version", you have the option of following the terms and
|
||||
conditions either of that version or of any later version published by
|
||||
the Free Software Foundation. If the Library does not specify a
|
||||
license version number, you may choose any version ever published by
|
||||
the Free Software Foundation.
|
||||
|
||||
14. If you wish to incorporate parts of the Library into other free
|
||||
programs whose distribution conditions are incompatible with these,
|
||||
write to the author to ask for permission. For software which is
|
||||
copyrighted by the Free Software Foundation, write to the Free
|
||||
Software Foundation; we sometimes make exceptions for this. Our
|
||||
decision will be guided by the two goals of preserving the free status
|
||||
of all derivatives of our free software and of promoting the sharing
|
||||
and reuse of software generally.
|
||||
|
||||
NO WARRANTY
|
||||
|
||||
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
|
||||
WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
|
||||
EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
|
||||
OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
|
||||
KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
|
||||
IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
|
||||
PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
|
||||
LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
|
||||

# EspSoftwareSerial
|
||||
|
||||
## Implementation of the Arduino software serial library for the ESP8266 / ESP32
|
||||
|
||||
This fork implements interrupt service routine best practice.
|
||||
In the receive interrupt, instead of blocking for whole bytes
|
||||
at a time - voiding any near-realtime behavior of the CPU - only level
|
||||
change and timestamp are recorded. The more time consuming phase
|
||||
detection and byte assembly are done in the main code.
|
||||
|
||||
Except at high bitrates, depending on other ongoing activity,
|
||||
interrupts in particular, this software serial adapter
|
||||
supports full duplex receive and send. At high bitrates (115200bps)
|
||||
send bit timing can be improved at the expense of blocking concurrent
|
||||
full duplex receives, with the ``SoftwareSerial::enableIntTx(false)`` function call.
|
||||
|
||||
The same functionality is given as the corresponding AVR library but
|
||||
several instances can be active at the same time. Speed up to 115200 baud
|
||||
is supported. Besides a constructor compatible to the AVR SoftwareSerial class,
|
||||
and updated constructor that takes no arguments exists, instead the ``begin()``
|
||||
function can handle the pin assignments and logic inversion.
|
||||
It also has optional input buffer capacity arguments for byte buffer and ISR bit buffer.
|
||||
This way, it is a better drop-in replacement for the hardware serial APIs on the ESP MCUs.
|
||||
|
||||
Please note that due to the fact that the ESPs always have other activities
|
||||
ongoing, there will be some inexactness in interrupt timings. This may
|
||||
lead to inevitable, but few, bit errors when having heavy data traffic
|
||||
at high baud rates.
|
||||
|
||||
## Resource optimization
|
||||
|
||||
The memory footprint can be optimized to just fit the amount of expected
|
||||
incoming asynchronous data.
|
||||
For this, the ``SoftwareSerial`` constructor provides two arguments. First, the
|
||||
octet buffer capacity for assembled received octets can be set. Read calls are
|
||||
satisfied from this buffer, freeing it in return.
|
||||
Second, the signal edge detection buffer of 32bit fields can be resized.
|
||||
One octet may require up to to 10 fields, but fewer may be needed,
|
||||
depending on the bit pattern. Any read or write calls check this buffer
|
||||
to assemble received octets, thus promoting completed octets to the octet
|
||||
buffer, freeing fields in the edge detection buffer.
|
||||
|
||||
Look at the swsertest.ino example. There, on reset, ASCII characters ' ' to 'z'
|
||||
are sent. This happens not as a block write, but in a single write call per
|
||||
character. As the example uses a local loopback wire, every outgoing bit is
|
||||
immediately received back. Therefore, any single write call causes up to
|
||||
10 fields - depending on the exact bit pattern - to be occupied in the signal
|
||||
edge detection buffer. In turn, as explained before, each single write call
|
||||
also causes received bit assembly to be performed, promoting these bits from
|
||||
the signal edge detection buffer to the octet buffer as soon as possible.
|
||||
Explaining by way of contrast, if during a a single write call, perhaps because
|
||||
of using block writing, more than a single octet is received, there will be a
|
||||
need for more than 10 fields in the signal edge detection buffer.
|
||||
The necessary capacity of the octet buffer only depends on the amount of incoming
|
||||
data until the next read call.
|
||||
|
||||
For the swsertest.ino example, this results in the following optimized
|
||||
constructor arguments to spend only the minimum RAM on buffers required:
|
||||
|
||||
The octet buffer capacity (``bufCapacity``) is 93 (91 characters net plus two tolerance).
|
||||
The signal edge detection buffer capacity (``isrBufCapacity``) is 10, as each octet has
|
||||
10 bits on the wire, which are immediately received during the write, and each
|
||||
write call causes the signal edge detection to promote the previously sent and
|
||||
received bits to the octet buffer.
|
||||
|
||||
In a more generalized scenario, calculate the bits (use message size in octets
|
||||
times 10) that may be asynchronously received to determine the value for
|
||||
``isrBufCapacity`` in the constructor. Also use the number of received octets
|
||||
that must be buffered for reading as the value of ``bufCapacity``.
|
||||
The more frequently your code calls write or read functions, the greater the
|
||||
chances are that you can reduce the ``isrBufCapacity`` footprint without losing data,
|
||||
and each time you call read to fetch from the octet buffer, you reduce the
|
||||
need for space there.
|
||||
|
||||
## SoftwareSerialConfig and parity
|
||||
The configuration of the data stream is done via a ``SoftwareSerialConfig``
|
||||
argument to ``begin()``. Word lengths can be set to between 5 and 8 bits, parity
|
||||
can be N(one), O(dd) or E(ven) and 1 or 2 stop bits can be used. The default is
|
||||
``SWSERIAL_8N1`` using 8 bits, no parity and 1 stop bit but any combination can
|
||||
be used, e.g. ``SWSERIAL_7E2``. If using EVEN or ODD parity, any parity errors
|
||||
can be detected with the ``peekParityError()`` function. Note that parity
|
||||
checking must be done before ``read()``, as the parity information is removed
|
||||
from the buffer when reading the corresponding byte.
|
||||
|
||||
To allow flexible 9-bit and data/addressing protocols, the additional parity
|
||||
modes MARK and SPACE are also available. Furthermore, the parity mode can be
|
||||
individually set in each call to ``write()``.
|
||||
|
||||
This allows a simple implementation of protocols where the parity bit is used to
|
||||
distinguish between data and addresses/commands ("9-bit" protocols). First set
|
||||
up SoftwareSerial with parity mode SPACE, e.g. ``SWSERIAL_8S1``. This will add a
|
||||
parity bit to every byte sent, setting it to logical zero (SPACE parity).
|
||||
|
||||
To detect incoming bytes with the parity bit set (MARK parity), use the
|
||||
``peekParityError()`` function. To send a byte with the parity bit set, just add
|
||||
``MARK`` as the second argument when writing, e.g. ``write(ch, MARK)``.
|
||||
|
||||
## Using and updating EspSoftwareSerial in the esp8266com/esp8266 Arduino build environment
|
||||
|
||||
EspSoftwareSerial is both part of the BSP download for ESP8266 in Arduino,
|
||||
and it is set up as a Git submodule in the esp8266 source tree,
|
||||
specifically in ``.../esp8266/libraries/SoftwareSerial`` when using a Github
|
||||
repository clone in your Arduino sketchbook hardware directory.
|
||||
This supersedes any version of EspSoftwareSerial installed for instance via
|
||||
the Arduino library manager, it is not required to install EspSoftwareSerial
|
||||
for the ESP8266 separately at all, but doing so has ill effect.
|
||||
|
||||
The responsible maintainer of the esp8266 repository has kindly shared the
|
||||
following command line instructions to use, if one wishes to manually
|
||||
update EspSoftwareSerial to a newer release than pulled in via the ESP8266 Arduino BSP:
|
||||
|
||||
To update esp8266/arduino SoftwareSerial submodule to lastest master:
|
||||
|
||||
Clean it (optional):
|
||||
```shell
|
||||
$ rm -rf libraries/SoftwareSerial
|
||||
$ git submodule update --init
|
||||
```
|
||||
Now update it:
|
||||
```shell
|
||||
$ cd libraries/SoftwareSerial
|
||||
$ git checkout master
|
||||
$ git pull
|
||||
```

/**
|
||||
The MultiDelegate class template can be specialized to either a queue or an event multiplexer.
|
||||
It is designed to be used with Delegate, the efficient runtime wrapper for C function ptr and C++ std::function.
|
||||
@tparam Delegate specifies the concrete type that MultiDelegate bases the queue or event multiplexer on.
|
||||
@tparam ISQUEUE modifies the generated MultiDelegate class in subtle ways. In queue mode (ISQUEUE == true),
|
||||
the value of QUEUE_CAPACITY enforces the maximum number of simultaneous items the queue can contain.
|
||||
This is exploited to minimize the use of new and delete by reusing already allocated items, thus
|
||||
reducing heap fragmentation. In event multiplexer mode (ISQUEUE = false), new and delete are
|
||||
used for allocation of the event handler items.
|
||||
If the result type of the function call operator of Delegate is void, calling a MultiDelegate queue
|
||||
removes each item after calling it; a Multidelegate event multiplexer keeps event handlers until
|
||||
explicitly removed.
|
||||
If the result type of the function call operator of Delegate is non-void, the type-conversion to bool
|
||||
of that result determines if the item is immediately removed or kept after each call: a Multidelegate
|
||||
queue removes an item only if true is returned, but a Multidelegate event multiplexer removes event
|
||||
handlers that return false.
|
||||
@tparam QUEUE_CAPACITY is only used if ISQUEUE == true. Then, it sets the maximum capacity that the queue dynamically
|
||||
allocates from the heap. Unused items are not returned to the heap, but are managed by the MultiDelegate
|
||||
instance during its own lifetime for efficiency.
