Stamp-C3 and I2C



  • Am I correct in that Stamp-C3 uses GPIO 0/1 for SDA/SCL?

    I saw it labelled as "Port-A." Does that refer to I2C?

    If it is not the default I2C, could I make it the I2C pins by doing this in the Arduino IDE?

    # define I2CSDA 0
    # define I2CSCL 1
    ...
    Wire.begin(I2CSDA, I2CSCL);
    


  • Hello @Bram

    have a look at this thread.

    Thanks
