Scrolling message display using two 'PIC16F84A' chips

by Roman P. Vaughan
(Auckland, New Zealand)

This message display was based on the dot matrix display in the project area on this site.

The reason I built it this way was because I had no 'johnson counter' so I got a second pic16f84a to act like one :P

The Letters a-z and numbers 0-9 are stored in an array. There is a second array containing the order the letters are displayed on the dot matrix and uses the binary left shift operator (<<) to move them to the left.
