LEDs only work with testfiles, not with pibooth

[bennnil]

I can not get the plugin to work. The provided testfiles work great, I have added the part to the printer config and it does not give me any errors. However the Leds stay dark no matter what I do.

Do you have a hint for me how to check if the plugin is correctly loaded ?

Thanks in advance!

How does your config part look like?

Hey @lxne, my config looks the following:

pictures_per_page = 1

[CONTROLS]

How long to debounce the hardware buttons in seconds

debounce_delay = 0.5

Which version of pibooth are you using?

Do you see the plugin on startup? Something like neopixel…

You renamed the file to 'pibooth_neopixel.py', right?

I added it like this and it is working…

Did you edit the file content? Two things to check

• 'num_pixels' has the correct value (amount of your LEDs)
• 'ORDER' is according to your lights (RGB, GRB or if you have white LEDs too, RGBW, GRBW) e.g. I had to set it to 'neopixel_spi.GRB'

If the lights are running you might have to play around with the multiplier here: time_between_pixels = raw_time_between_pixels * 1.7 With 32 LEDs and a 5 seconds preview, I had to set it to 1.7 for it to have good timing.

Thanks for looking into this. It seems it was a problem with a PATH variable that has been declared such that the changes I made were not used. I did a whole new setup with pibooth to figure this out. Now it works like charm!
