I made a simple LED matrix with shift registers in both row and col(anode and cathode). Now I want to build a 8x8 RGB PWM matrix so that I can control the color of each LED in the matrix.
Here is the datesheet of 74hc595
One thing I'm struggling with is which IC to use on the cathode end. Previously, I simply added another 74HC595 and simply set row(cathode) that I wanted to light up and set RCLK. I was hoping to use the same approach, but I'm not so sure with the PWM.
I also considered using another TLC5947 but I don't think it works as source current?
EDIT: the micro controller I'm using is atmega32u4 at 16Mhz
