I trying for several hours the example GxEPD_SPI_TestExample.ino with WaveShare Display 7,5 inch b/w/r and HAT Interface to Wemos D1. Wireing as recommended in Sketch for Wemos
// mapping suggestion from Waveshare SPI e-Paper to Wemos D1 mini
// BUSY → D2, RST → D4, DC → D3, CS → D8, CLK → D5, DIN → D7, GND → GND, 3.3V → 3.3V
I also uncommenting the corresponding line in sketch
#include <GxGDEW075Z09/GxGDEW075Z09.cpp> // 7.5" b/w/r
I do not anything else modified inside the sketch
By uploading the sketch with connected D1 - HAT - Display, the compiling running without error but at the end no connection to the serial port will be established - resulting in timeout, see error below
Serial port COM3
Traceback (most recent call last):
Checking the com ports, no error, they are working with different sketches.
Without connection to HAT and Display, the sketch is working and I do get information on the serial monitor. checking wiring and so on …
I do not have any idea, also didn’t find a hint somewhere else.
Would be great if there is any idea or hint for solution.
