Question: Substitute PD6/ADC9 for another pin? #1

Closed mbaran5 closed 3 years ago

mbaran5 commented 3 years ago

I was looking to see if I could wire this up to an Arduino Pro Micro that I already own and put inside of an existing (but terrible) Wii Classic to USB case, but noticed one of the pins used is PD6/ADC9 which is unused on a Pro Micro. Could another pin be substituted that isn't already in use?

Using this as my reference for which pins are mapped to which from the ATMEGA32U4: http://cdn.sparkfun.com/datasheets/Dev/Arduino/Boards/Pro_Micro_v13b.pdf

Thanks!

Yes, that's no problem. I²C is done in software so any digital pin works. In controller_adapter.ino just modify the line #define PIN_SCL2 12 to your preferred pin.

Cool, thank you! I realized after posting this that both of my Pro Micros are 5v/16mhz, so I will need to rethink the plan.
