Hello everyone,
I am facing a strange problem. The code I wrote (which is not yet complete) works fine but as soon as I uncheck the comments on lines 124 and 125 I have nothing left on the SSD1306 display. That said, if I comment out other things (eg the StartUp routine), I have the same phenomenon. As if the program is lost when displayed (but continues to run anyway).
Can you help me ?
Please, I am new to arduino, I started writing in C 2 weeks ago.
Thanks for your help.
Steve
