Raspberry pi gpio PWM not working #1916

Open neidaskr opened 2 months ago

neidaskr commented 2 months ago

FPP 7.5 on raspberry pi zero 2w

When you enable PWM the pins stop working, but when you turn PWM off the pins start working

PWM on PWM off

patdelaney commented 2 months ago

@neidaskr did this work on Previous version? What do you have connected to this so that I can test and try and reproduce? Are you using a mofset and then connecting to a dumb RDG strip?

neidaskr commented 2 months ago

I tried on an older version and it still didn't work. I use 3 mosfets which are connected to RGB led

patdelaney commented 2 months ago

Thanks I can test this when I get home.. Can you test it on version 8? https://github.com/FalconChristmas/fpp/releases

I'll send you a zoom link after work and we can chat about this

This might be fixed in 8 with the updates to the GPIO table for the Pi's.

neidaskr commented 2 months ago

Already tried on that version

@neidaskr Please try the very latest fpp 8. Install FPP Beta 8 image, then go through the upgrade process and let us know how you go. It's not clear that you actually tried a version of 8 new enough to include the change Dan mentioned.

In the latest version(8,0) it still doesn't work. When i turn on PWM it just locks the state that the pin is in. For example, if i turn the pin state high in the display testing section, and then turn on PWM the pin stays locked and doesn't turn off in any way. I've tried to test if the PWM works on my pi with raspberry os, and it worked. So my pi isn't the problem here.
