Im trying to make the timer work on a 16f877, i have done this before without issues.
This time im using a ks0108 type LCD, and when i activate the timer in the program it jams up and scrambles all the data on the screen, (looks like i have typed the same thing over and over and over)
The program just locks up and has to be reset.
Without the timer active the program runs flawlessly. The LCD is using the entire port B for data, and most of port D for control lines.
Is there any reason why this should be happening???
