i am trying to connect my Waveshare ePaper display module to ESPeasy but it will not work.
Tried all kind of settings, still no function.
Switched to Arduino example code from Waveshare Website on Arduino Uno and the display works like a chram.
So the problem is anywhere in my settings, i guess.
Maybe you guys can help me
Here are my specs / configs:
ESPeasy Build:
ESP_Easy_mega_20221105_display_ESP32_4M316k
e-Paper Module:
- Waveshare 2.9 / v2 Rev2.1
- 296x128 Pixel
Tested ESP:
- ESP32-S
- ESP32 D1
- ESP8266
SPI setting on ePaper Module:
- 4-Wire
Info text from Waveshare Webpage:
V2 hardware and interfaces are compatible with V1
