Hi
I am having trouble getting my 2x16 display to display. Am using a 16f690, is this ok? The simulation works fine , but when connected to the LCD, just line 0 comes up with all dots on.
Any ideas please
JOHN

Hi
Had a quick look, it appears you have the watchdog turnt on in config, disable it and try again, you might also want to turn on the power up timer, let us know if it works

Just a thought, I know it would help me starting off, this can be used as an example

Cheers
