My first guess is to try reducing the I2C bus speed, but I’m not sure which I2C bus corresponds to I2C0 so I feel like I’m hacking away blindly. Using I2C eeproms both on the module and carrier, and other hardware information it performs modifications. I consider wiring it up with the I2C interface, fully knowing that it can be interacted with over SPI as well, which would be faster Use BOARD=sensebox_samd21 with the make command 1 Code Examples This setup works great on a RedBoard, but with the SAMD21, all I get back from the EEPROM reads is 0xFF With I2C, the Master is the far more. 11ac wireless adapter and cable. gh jr. I2C is incredibly popular because it uses only 2 wires, and like we said, multiple devices can share those wires, making it a great way to connect tons of sensors, drivers, expand. . regan fixx
