4 years ago Hello @melwinek , did you already try one of those two alternative display-models in your config?

3 years ago @melwinek did you ever get this working ? I have a 2.13 display (SKU 12672) connected via a e-Paper ESP8266 Driver Board (I bought them together and there's a ribbon cable between the board and the display. I have similar yaml to yourself and also see 'Timeout while displaying image' in the logs
yaml looks like :
spi:
clk_pin: D5
mosi_pin: D7
font:
- file: 'materialdesignicons-webfont.ttf'
id: icon_font_30
size: 30
display:
- platform: waveshare_epaper
cs_pin: D8 # GPIO 15
dc_pin: D2 # GPIO 4
busy_pin: D0 # GPIO 16
reset_pin: D1 # GPIO 5
model: 2.13in
full_update_every: 6000
update_interval: 30s
lambda: |-
it.print(0, 0, id(icon_font_30), "Hello World!");The manual for the board is here : https://www.waveshare.com/w/upload/a/a7/E-Paper_ESP8266_Driver_Board_EN.pdf I needed it to deduce the correct pin assignments. It also has a paper type switch but I've tried in both A & B and still get the same error :(

3 years ago Hi, on ESPHome 2021.8.0 with the same config on a ESP32 I have the same issue. The text gets displayed, however updated every second (the display kind of blinks) with error messages at random times. Has anyone solved this?
update: seems like the documentation or code on the update_interval is wrong. The documented 10s default updated interval is not implemented. My solution is to specify it (with a decent time >2sec), now the errors are gone.
update_interval: 15 sec
