Simplest hardware and code to blink a LED with PIC18F4620

[AvionicsMaster1]

Well, here's another thought. I don't see CONFIG3H in your configs. If I read the datasheet correctly the PBADEN needs to be set so PortB goes to all digital after a reset. I remember Darrel saying if you set any configs PBP overwrites them all and replaces them with your configs. So after a reset all the ports become analog if the PBADEN isn't set correctly. Again, if I read that f.... datasheet correctly.

I hope I quoteth the great and omnipotent one correctly. Better yet, I hope I'm right.

Sorry. For some reason I thought you were using PortB.0. After pulling my head out it looks like your LED is on PortE.0. My apologies.

I thought I'd fire up the old Proteus and see if I could duplicate the problem. Granted, this doesn't always reflect real world situations but this program and schematic will blink an LED on porte.0 and porte.1.

CLEAR

start_here:

HIGH porte.0
PAUSE 500
LOW porte.0
PAUSE 500
HIGH porte.1
PAUSE 500
LOW porte.1
PAUSE 500

GOTO start_here

Where can I find "ALLDIGITAL.pbp"? Either download the file or get the code?
Thanks
