Hey,

I like QLC+ very much, but now I want to go further. I need support for Matrixes like http://www.adafruit.com/products/420

is it possible to add Support for LED Matrixes ?

If I use this (https://github.com/hzeller/rpi-rgb-led-matrix), I need 2 programs to control it..

Best Regards
Pascal

RGB LED Panels are already supported via the SPI plugin, as shown here

The Adafruit panel is a custom solution based on GPIO and if I'm not mistaken you need to wire 12 signals + GND.
With SPI you need just 3 wires.

Anyway, if you have some coding skills, you can write a plugin for QLC+ to drive those kind of panels (wondering how many with the same pinout are out there...) and then send us a pull request on GitHub :)

yes you need to wire 16 signals incl. GND

but i like this kind of matrixes more and nearly every video wall in Clubs are based on this matrixes.

I have some coding skills but no idea how to start and don't understand the whole way to control this
