Update:

I have added the following lines to my Blinky LED program:

Code:
ANSEL0 = 0              ' Set all PORTA as digital I/O
ADCON0.0 = 0            ' Disable A/D module
TRISA = 0               ' Set PORTA as output
I was confident I would see a blinking LED after these changes but was sadly mistaken...

Cheers
