#110684 - multiplexing Responding to: ???'s previous message |
Thanks Neil. I did intend on doing the multiplexing in the controller.
I had originally wired it up with some pullup resistor to the BCD-decimal decoder and could only get it to drive row 7. But I dinked around with it more and I wasn't sending the bit information to those 3 pins. Got it all straightened out and it's operating properly. |
