Hello. I am trying to compile a program but receive a error message regarding the oled part.
I have tested the oled and it works fine with other programs.
I have tried to arrange this program/edit, but receive error message regarding oled.
Can someone please help? Thanks , in advance.
The program should be ok, could it be a problem with something else?
There is also a program part for sensors, and one part for functions. I did not add them in this message.
Error message:
