Hello,

i purches the 4.7 eInk Display with the integrated ESP32 but i cant do anything with it.

I connected it via USB -C and the Arduino IDE 1.8.19 → downloaded the EPD47 Library from the wikipage: https://wiki.dfrobot.com/ESP32_E_ink_Screen_4.7inch_SKU_DFR0835

But i couldnt find the 32_package_1.0.5.exe so i took the ESP32 Board Library from Espressif Systems Version 2.0.4.

I set the Board to:

Tried to upload various sketches and everything seems fine but the display wont do anything.

This is my result for uploading the EPD47 Demo:

The Screen:

I get input over the Serial Monitor from the Board, but i dont know what that means:

Please help me debug the error, or should i send the Board back?

Best regards
