Hi all,
I am new user for the pic microcontroller. Can anybody provide me some idea about how to scroll the text from right to left. i was using the pic16f877a and shift register to control it.

I would love to see this thread ongoing and finally come up with a working circuit and code.
Nice design idea there.
