I bought RedBear Duo for the high performance and size.
But, when I try to use Arduino libraries such as OLED or sensors, I faced a problem with pin numbers.
The error message is
fatal error: pins_arduino.h: No such file or directory
fatal error: wiring_private.h: No such file or directory
Because the pin numbers for general Arduino are already allocated, I think I have to change the header file. But I don't have any idea how to change and should we do this everytime.
I really want to ask how to solve this error from the roots. Where can I find the header file for RedBear Duo and what do I have to with them?
