I’ve just installed my automation hat and enabled I2C support on the pi 3 using raspi-config. As I’m not intending to use python but rather write my own code in C I haven’t run the pimoroni install scripts.
I ran i2cdetect -y 1 and the output correctly showed a device at 0x48 (I understand that this is the ADC). Having read the pin out information I believe that the three LEDs are driven from an SN3218A device which is located on the I2C bus at 0x54. Should I be seeing this reported with the i2cdetect command?
I’ve not tried sending any I2C commands yet but simple gpio commands using pigpiod correctly toggle the relays and open collector outputs so I believe the board to be working.
Any assistance gratefully received.
