LED Strip Lightpainting Skript-Error?

by Maaky on Mon Aug 07, 2017 3:18 pm

Hey girls and guys,

im trying to get Lightpainting-Raspberry 3 to work. I got an 1m LED Strip with 32 LEDs. Im working with the guide: https://learn.adafruit.com/light-painti ... spberry-pi .
Im actually testing another script with rainbow-glow etc. and that just works fine. So i guess all needs software and hardware-wise should be okay. I now think maybe its the code.

I only get white LEDs flashing in white or lightblue with the skript. Tested out the converting and the picture looks good in converting. For testing purpose i just made a 32x32 png with red and green. No errors till "displaying" or anything other.

Someone got an idea? Where the bug might be ? or am i just stupid and overworked? :)

Cheers Maaky

Hi,
okay i found my "bug". Its the gamma correction, which needs to be done with the LDP8806. I just used an WS2801 strip which didnt need the correction.

cheers.
