LED Matrix RGB custom pcb
Posted: Mon Dec 03, 2012 12:44 pm
I am working on a project to make a 8 by 8 led matrix and I am using the schematic from the LED Matrix - Serial Interface - Red/Green/Blue https://www.sparkfun.com/products/760
I have this matrix wired up on my breadboard with my arduino wired to it at the moment. I have tested all the connections and I think I have narrowed it down to the atmega328p on the matrix backpack. I am using the example code and it will not flash it just gives me 2 lines of green 2 lines of red and 2 lines of blue the other 2 lines are off. I have the feeling it has something to do with the clocks not matching up. can anyone think of something I missed when I tried to recreate this board on my breadboard?
