Hello folks,
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

ESPeasy Settings:
HARDWARE -> SPI Interface:
HSPI: CLK=GPIO-14, MISO=GPIO-12, MOSI=GPIO-13
DEVICES -> Display - eInk with Lolin ePaper screen:
GPIO → EPD CS: GPIO-26
GPIO → EPD DC: GPIO-27
GPIO → EPD RST: GPIO-33
GPIO → EPD BUSY: -none-
eInk display model: Waveshare 2.7" (264 x 176px)
Connection Display -> ESP32:
Busy -> n.c. / when connected ESP will freeze
RST -> GPIO-33
DC -> GPIO-27
CS -> GPIO-26
CLK -> GPIO-14
DIN -> GPIO-13
GND -> GND
VCC -> 3.3v / 5v (testet both)
Tested with all display model types:
- IL3897
- UC8181D
- SSD1680
- Waveshare 2.7"
[Problem] ePaper module won't do anything

Re: [Problem] ePaper module won't do anything
Those ePaper devices have the 'habit' of using a different controller for each different display resolution. Your device is the 296x128 pixel version, where you selected the 274x176 pixel model.
I'm still thinking about a way to easily support all those different display controller models, but haven't found a solution yet
