Help please need to repair unit using PIC16F84P only have hex code.
I am currently staying overseas away from home and need to repair a unit based on a PIC16F84. I have a PICKit2 with me but only the relevant hex file and cannot track down a PIC16F84. I think I have found a source for a PIC16F84A locally and can easily obtain a PIC16F628A.
From my interpretation of the PIC documentation it would appear that I may be able to use the 16F84A (it is running at 4MHz) by simply loading the hex file.
Grateful for any advice.
Thanks
David

I don't think you'll experiment any problem from 16F84 to 16F84A.

from the .HEX, you can create the .ASM and then modify it for the 16F628.

Thanks Steve, that was my reading of the Microchip guidance but the 16F84A is very expensive here so didn't want to go ahead without being certain.
Guess I really ought to get to grips with MPLAB to learn how to convert .hex to .asm - so far I have stuck with MCSP - it seemed less daunting! It would make financial sense to use the 628.
