Here is the second iteration of the circuit design for running the 8×8 LED Matrix. This time I attempted to lower the number of signal lines being run out of the ATMega1280 microcontroller by using 2x 74HC595 Shift Registers. Doing this reduced the number of signal lines from 16 to 3, a huge drop, with no noticeable loss of performance.
This circuit is only running the green LEDs in the display however.
