Hi I will probably be taken to task over this, but please bear with a = newbie who wants to share your passion.... Programmer is the kit (Ref no. 81) based on the article by Charles = Manning in Elctronics Australia, which has passed all tests = successfully. Program is the lights.hex test program supplied with the kit (Other = programs have also been tried) Programming software is Picall Windows version 1.10d - Feb 2002 (others = have also been tried, including a full simulation run in MPLAB) The prblem is that whenever the chip is programmed I get the error = message: Program: address =3D 0000 buffer =3D 2810 device =3D 3FFF As a matter of fact, whatever program I try to download to the chip, I = invariably get the same message with whatever is in the buffer at = address 0000. All possible fuse combinations have also been tried. Can anyone please put me out of my misery?
