Redragon K556 Devarajas about dk63

I think I've reverse engineered the matrix:

I started looking into reverse engineering the K556 firmware today. I asked Redragon support for the FW updater and they sent it to me. I've extracted the FW and loaded it up in Ghidra and have been poking around. I think I've found a function that defaults the flash so far. My primary goal is to find the functions that control the LEDs so I can see if it has a direct control mode (and if not, possibly add one).

I've created a new channel on the OpenRGB discord #redragon-hacking if you want to join. I'm posting my progress there.

hey, i want to do the same thing i have a k551 and it has the same chip, are you able to trace the pinout? i dont have a tester, also i have the firmware file if you think you can help me reverse it, i tried but i really have not a lot of experience with reverse engineering, i briked my keyboarrd and flashed the k556 firmware on my keyboard and it worked so the k551 and k556 must be the same in almost every aspect
