# SD-card
|

Data can be stored on an SD-card if one is availabe. Simply choose the file in src/hal and add the following lines to your hal-file:
|
||||
|
||||
#define HAS_SDCARD 1 // this board has an SD-card-reader/writer
|
||||
#define HAS_SDCARD 1 // this board has an SD-card-reader/writer, with SPI interface
|
||||
OR
|
||||
#define HAS_SDCARD 2 // this board has an SD-card-reader/writer, using native SD interface
|
||||
|
||||
// Pins for SD-card
|
||||
#define SDCARD_CS (13) // fill in the correct numbers for your board
|
||||
#define SDCARD_MOSI (15)
