Raspberry Pi was one with the option I found but I wasn’t sure if it works as a part between the PC (vvvv) and the RGB panel or I have to run straight from the raspberry.
Write me please the exact process ? - only in simple points
what do I need to get data from vvvv (PC) to RGB led panel throught Raspberry Pi?
its not so pretty straight forward and i have not found a way to do this yet.
on the raspberry side i guess you would need to write a wrapper that prepares for example a network string you send to displayable pixel data. the above mentioned library has two wrappers for that in c# and python.
if you do not need to use exactly this matrix, there are options avaliable that use leds with the ws2812 controller, that are probably a bit more out of the box friendly.
