Hello @hrsavla there are multiple issues to fix this for compilation with Arduino framework 2.0.1. I've attempted to solve those issues here - try it at your own risk. Thanks Felix

Hi I had the same problem, but the suggested (uint16_t) correction in M5EPD.cpp lead to another problem: in the files adc.h, the statement #include "soc/adc_channel.h" must be inserted after tge firts #include statement. Chris
