I found on instructables an 8x8 led matrix which uses shift registers to address each individual led. I modified the design so that it uses rgb leds instead and is controlled from a pic18. What I would like to do is be able to set each led at different brightness levels so that I can get a fading effect in some animations. Would i need to replace the shift registers with a multiplexer and added a bunch of external PWM ICs to the design.
