Open ack202 opened 4 years ago

ack202 commented 4 years ago

Describe the bug Whenever the display is enabled in the config the service is stuck during startup. See below:

After disabling the display in the config pwnagotchi will start just fine.

ui:
    display:
      enabled: false
      type: 'waveshare29inch'
      color: 'black'

Environment (please complete the following information):

Any idea?

Hmm this looks like similar issue i faced with 2.13 inch display. The display becomes frozen and ends up freezing pwnagotchi too. So i found its an issue with the original python driver from waveshare itself

So i ended up writing a freeze recovery routine in the original waveshare code. You can see it here

720

Refer the last commits on this pull request to see the anti freeze code. Bascially in the busy loop it will try to reinitialize itself by turning off and on again. You could try same approach to solve the issue. There is very little documenation that i could understand from waveshare wiki so all this is based on reading their python code and repurposing it. Hope this helps

Thanks for the hint. Used your code but display is still black. Will investigate further.

moheshmohan commented 4 years ago

That code is for 2.13 inch b&c variants of display, you'll have to check offical waveshare epaper repo and improvise it for 2.9inch display...i think 2.9inch also has a, b, c and d variants so u will have to work one based on ur variant

ack202 commented 4 years ago

Got it running with the new drivers for the 29bc model. After each refresh the display flickers on/off for about 10 times. Did you run into something similar?

moheshmohan commented 4 years ago

I didnot see flicker for 10 times but may be 3 or 4 on 2.13bc. But yes there is that flicker on refresh

darkr4y commented 4 years ago
