Hi all,
well after getting my programmer to work I loaded the example hex file that
flashes an LED on port RB1 and wow! the LED flashes ! ;-)

I have written a bunch of code in Hi TECH C integrated with Microchips
MPLAB. To start of with I wrote my own version of the flashing LED program
(attached) which flashes an LED on pin RB0. I compiled the code and loaded
the hex file. However this time no flashing LED :-(

Can anyone help me with this? Is there a bug in the code? I have gone over
it and can't see any obvious mistakes.

Is there anything special I have to do in MPLAB or HI TECH cmd line switches
to get code that will run?

Thanks for you help
regards
James Fitzsimons
