Can't get WaveShare V4 Working
Closed this issue · 15 comments
Hallo,
Running latest image v2.8.9 on Raspberry Pi zero 2W with waveshare V4
Config set to Waveshare_4
No display, anything else I should do?
Display - https://www.pishop.co.za/store/213inch-e-ink-display-hat-for-raspberry-pi-250x122
Got a V4 sticker on the bottom
Config
ui.display.enabled = true
ui.display.type = "ws_4"
ui.display.rotation = 180
Thanks!
ui.display.type = "waveshare_4"
Updated but still no display? :(
ui.display.enabled = true
ui.display.type = "waveshare_4"
ui.display.rotation = 180
Log shows
11:39:16 [INFO] initializing waveshare v2in13_V4 display
11:39:16 [INFO] clearing the display ...
In which file are you configuring?
translated by google.
sudo nano /etc/pwnagotchi/config.toml
It should work...
I use the same settings and have never had this problem.
Raspberry Pi zero 2W & waveshare V4
ui.display.enabled = true
ui.display.rotation = 180
ui.display.type = "waveshare_4"
ui.display.color = "black"
run:
sudo systemctl stop pwnagotchi && sudo pwnagotchi --debug
See if any errors pop up
Getting a bunch of these

Also just noticed now
default.toml :
ui.display.enabled = false
ui.display.rotation = 180
ui.display.type = "waveshare_4"
config.toml
ui.display.enabled = true
ui.display.type = "waveshare_4"
ui.display.rotation = 180
ui.display.color = "black"
How is your soldering, or did you use hammer pins?
Think they pretty good, fluxed and all
Was thinking I'll try it on the SPI port tomorrow
Screen is brand new, but pi was used for other stuff, so not sure if something might be broken
That looks good, if there are no noticable errors in --debug than it must be either faulty display or broken pi. Display being the one that breaks easier.
It seems to me that there are some pins that are cold soldered or with little flux.
Before buying new hardware I suggest you try to resolder all the pins at a slightly higher temperature and with plenty of flux.
Over time, the cold soldering could come off and you wouldn't notice
ui.display.type = "waveshare_3"
Also as @AleTornesello suggested, try resolder
i wouldnt use _3, _4 is best with a V4 sticker, if no display after reheating those pins display may be damaged
