P10 32x16 LED panel ¼ SCAN Working With NO C address

Other Hardware LEDs and Multiplexing
1

I have the panel working with no split screen now, still working on multi-color - but can change R/G/B in address. The panel I am using is a P10 with A and B addresses only - no C or D. I altered the matrix so the panel is complete, but now I am getting too much flicker. I will share the code in the next line.
Still working on this, I am better at hardware than software, don't judge.
