      I have just got an M5Paper and started playing with its capabilities. I tried the examples in the M5EPD library but just get errors. It also takes an age to compile. The M5GFX library examples work fine, as does UIFlow blocky/micro-python. Has anyone else noticed issues with the M5EPD, none of the examples even compile?

        Hello @mnwh

        hmm, I can compile let's say the M5EPD Hello World example just fine.

        Care to share the compiling error you're getting?

        Thanks

          If your error has something to do with the "ADC1_GPIO35_CHANNEL not defined" error I got, then you can "simply" insert this
          #include "soc/adc_channel.h"
          into the
          \Documents\Arduino\libraries\M5EPD\src\M5EPD.cpp.

          I wrote this in a new line (line 4)

          It's caused by a change from espressif 3.3 to 4.4.
