# Use case
@ -11,7 +13,7 @@ Paxcounter is a proof-of-concept device for metering passenger flows in realtime
Intention of this project is to do this without intrusion in privacy: You don't need to track people owned devices, if you just want to count them. Therefore, Paxcounter does not persistenly store MAC adresses and does no kind of fingerprinting the scanned devices.
Bonus of this project is that metered data is transferred via a LoRaWAN network, not via usual GSM/LTE or Wifi uplink.
Metered counts are transferred to a server via a LoRaWAN network, and/or a local SPI cable interface.
You can build this project battery powered and reach a full day uptime with a single 18650 Li-Ion cell.

# Preparing
Before compiling the code,
- **edit paxcounter.conf** and taylor settings in this file according to your needs and use case. Please take care of the duty cycle regulations of the LoRaWAN network you're going to use.
- **edit paxcounter.conf** and tailor settings in this file according to your needs and use case. Please take care of the duty cycle regulations of the LoRaWAN network you're going to use.
- **create file loraconf.h in your local /src directory** using the template [loraconf.sample.h](https://github.com/cyberman54/ESP32-Paxcounter/blob/master/src/loraconf.sample.h) and populate it with your personal APPEUI und APPKEY for the LoRaWAN network.

il3820: 200x300x1
command
0x22: assign actions
0x20: execute actions
action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 10ms
Enable Charge Pump and Clock require about 100 to 300ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump is always enabled. Charge pump can be enabled/disabled via power save message
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.
LUT for the 296x128 device (IL3820)
LUT (cmd: 0x032 has 30 bytes)
section 6.8 of the datasheet mentions 256 bits = 32 bytes for the LUT
chapter 7 tells 30 bytes
according to section 6.8:
20 bytes waveform
10 bytes timing
1 byte named as VSH/VSL
1 empty byte
according to the command table, the lut has 240 bits (=30 bytes * 8 bits)
LUT / Refresh time
total_refresh_time = (refresh_lines + dummy_lines*2)*TGate*TS_Sum/f_OSC
f_OSC=1MHz (according to the datasheets)
refreh_lines = 296 (for the waveshare display, 0x045 cmd)
dummy_lines = 22 (for the upcoming u8g2 code, 0x03a cmd)
TGate = 62 (POR default, 0x03b cmd)
TS_Sum: Sum of all TS entries of the second part of the LUT
f_OSC: 1MHz according to the datasheet.
so we have
total_refresh_time = 21080*TS_Sum/1000000 = 21ms * TS_Sum
This file includes two devices:
u8x8_d_il3820_296x128 --> includes LUT which is probably from the WaveShare 2.9 Vendor
u8x8_d_il3820_v2_296x128 --> includes LUT which was optimized for faster speed and lesser flicker

SSD1606: 128x180x2
two-bit, four graylevels
command
0x22: assign actions
0x20: execute actions
action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 267ms
Enable Charge Pump and Clock require about 10ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump and clock are only enabled for the transfer RAM to display
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.

0x22: assign actions
0x20: execute actions
action for command 0x022 are (more or less guessed)
bit 7: Enable Clock
bit 6: Enable Charge Pump
bit 5: Load Temparture Value (???)
bit 4: Load LUT (???)
bit 3: Initial Display (???)
bit 2: Pattern Display --> Requires about 945ms with the LUT from below
bit 1: Disable Charge Pump
bit 0: Disable Clock
Disable Charge Pump and Clock require about 267ms
Enable Charge Pump and Clock require about 10ms
Notes:
- Introduced a refresh display message, which copies RAM to display
- Charge pump and clock are only enabled for the transfer RAM to display
- U8x8 will not really work because of the two buffers in the SSD1606, however U8g2 should be ok.

UC1611s 160x256
UC1611 160x240
Differences:
UC1611 0xa8 cmd: enables 80 display rows
UC1611s 0xa8 cmd: controlls graylevels
UC1611 0xc0 cmd: single byte command for LCD mapping control
UC1611s 0xc0 cmd: double byte command for LCD mapping control
