I copied the digitizer code (only changed the pins), and have it running. The behavior is not what I expect though, “Mode 1” lights up all the colored LEDs, but none of the digits; “Mode 2” – 4 light all the segments in each digit for all the digits, but none of the LEDs. It looks like it doesn’t matter what I put in my bit, if I put B1xxxxxxx, it turns all the LEDs on, and B0xxxxxxx turns all the segments of all the digits on.

I realized initially I had one of the shift registers in backward (I thought both were supposed to be pointing to the center of the board), and the backward one got very hot. Do you think this burnt out, and that is why I’m seeing this behavior?
