you are welcome. I am glad to hear you got it working and thank you for reporting back here.

thanks. Most likely the issue is the double initialisation of Serial. If you have a look into M5.begin() you'll see that by default it initialises Serial as well.

    if (SerialEnable == true)
    {
        Serial.begin(115200);
        Serial.flush();
        delay(50);
        Serial.print("M5EPD initializing...");
    }

So I suggest you change your code to:

#include <M5EPD.h>

M5EPD_Canvas canvas(&M5.EPD);

void setup() {
  M5.begin();
  M5.EPD.Clear(true);
}

void loop() {
}

Note: untested as my M5Paper currently is in a long term battery test.

Hope this helps.

Thanks
Felix

#include <M5EPD.h>

M5EPD_Canvas canvas(&M5.EPD);

void setup() {
Serial.begin(115200);

Serial.printf("Begin\n");
delay(1000);

M5.begin();
M5.EPD.Clear(true);
}

void loop() {
yield();
}

would you mind sharing one of the examples which fails on your M5Paper?

Thanks
Felix
