Can't get WaveShare V4 Working

[djvdberg]

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"

[djvdberg]

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 ...

[ianfs2]

In which file are you configuring?

translated by google.

[djvdberg]

sudo nano /etc/pwnagotchi/config.toml

[ianfs2]

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"

[jayofelony]

How is your soldering, or did you use hammer pins?

[djvdberg]

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

[jayofelony]

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.

[AleTornesello]

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

[code-for-kaffee]

ui.display.type = "waveshare_3"

Also as @AleTornesello suggested, try resolder

[rai68]

i wouldnt use _3, _4 is best with a V4 sticker, if no display after reheating those pins display may be damaged

[AchimGrolimund]

hey @djvdberg dose it work now for you?

i have a similar issue but with other Hardware (Raspberry pi 4B) https://github.com/jayofelony/pwnagotchi/issues/200

I see also only e-ink is busy but nothing happens on the display.
