Hi everybody,
I am a beginner with teensy and I can not compile the code, it seems it comes from the round function.
I tried to put #undef round at the beginning of the sketch but it does not fix the problem like in this post:
https://forum.pjrc.com/threads/35391-Error-Compling-for-board-Teensy-3-2-3-1?highlight=wiring.h
Any suggestion to help me?
