Im using the adafruit bme280 lilbrary, RTClib, SD card library.
The bme280 library ask for the number pins for the I2C connection like this:
Code: Select all
#define BME_SCK 21
#define BME_MISO 12
#define BME_MOSI 11
#define BME_CS 20
Code: Select all
#if defined(ARDUINO_ARCH_SAMD)
// for Zero, output on USB Serial console, remove line below if using programming port to program the Zero!
#define Serial SerialUSB
#endif
How do I make the connections with these libraries with my m0 board.
