Hi! I finished soldering my Peggy 2 together and tried uploading the row/column tester sketch, but when it scrolls down through the rows, one column is illuminated all the time and all of the LEDs to the right of that column don't follow the sequence. They do faintly illuminate, so I'm pretty sure they're soldered properly. What could be wrong?
I should note that when I was putting the chip in the U5 DIP socket, one of the pins got kinda mangled and I had to straighten it out with some needlenose pliers. I wouldn't be surprised if that was damaged.
Thanks for any help you can provide. It's been a fun project!
