Continuing the discussion from Port to Arduino pin# definition or graphic?:
@beegee apologies for re-opening this, but after a little more investigation I think there may still be some information missing that would go a long way towards convenience for your customers using the stamp module.
You indicated a great graphic in the link above, however it does not appear to show which pins are what pin number as the RUI 3 API takes them via the arduino IDE.
For example, P1.04 is physical pin 28, but you must call digitalWrite(36, val) to write to that pin. It would be great if there was an updated graphic that had the digital pin assignment as well as the physical and port information for each pin as is used by RUI3 / Arduino API.
So far I’ve had to essentially go through probing each pin with a multimeter to figure out which pin is which, would like to spare others from the same fate!
