I am building a sign with 6 LED arrays. The arrays are 5x7. I wrote the code to represent the entire alphabet (one letter per array). To do that I’m using 7 of the output pins (28X) and five of the pins on Port C as outputs. I don’t mind using one 28X on each array but I need help synchronizing them so the code running on each chip executes at the right time.
