Hello, My senior design team and I are using the new 328-PB chip on our custom PCB. We have broken out some of the additional pins the PB offers over the old 328-P.... Unfortunately we don't know how to access these pins as we don't know that the arduino IDE recognizes them.
We are using tinyISP to program along with Watterott's opitboot configuration. https://github.com/watterott/ATmega328PB-Testing
Maybe we can just define our pins as 20-23 and the IDE will recognize them as just regular pins?
Point being as a sanity check I tried accessing digital pin 9 on a 2560 with #define ledPin PH6...and it did not work (compiled/uploaded fine), but #define ledPin 9 does. I guess the AVR designations don't work in arduino.
Any advice would be appreciated!
