Reverse engineering hardware

YentlHendrickx commented 5 months ago

Hi,

First of all nice work to all contributors on the client and library!

I was wondering if you had any idea on how the LEDs are driven hardware wise? I looked into the hardware myself with the interest of potentially using my own controller to drive these. As that would open a lot more possibilities!

Unfortunately the part numbers of the 2 main chips are rubbed off. I have looked for the ones that did have their part numbers and did find some info here and there, not much of value. I've got a 16x16 variant and for that one I believe it might be 6 16-channel LED drivers along with 2 8-channel multiplexers (3 LED drivers per 8 rows [R, G and B], 1 channel per row for the MUX). However it can also simply be individually addressable RGB LEDs (doubt it since those are usually more expensive, and we all know how it goes).

Do you have any ideas yourself (or clues in the software)? It might be helpful on my quest to reverse engineer this thing.

(Sorry in advance if this is a bit off-topic since it's not about the software) Thank you!

@YentlHendrickx I'm not too hardware savvy, but I was able to get clear photos of the main chip with the part number on it. I don't know anything about how the LEDs are driven but maybe the part number could be helpful.
