Obtain the HEX code, convert HEX code to ASM, edit the program, and with ic-prog you can burn the pic.
Correct, burn modified code into the PIC with something like IC-Prog or
Win NOPPP. Not the burning, but the modifying is far too difficult. The
read HEX to ASM is non descriptive. All registars and more importantly
the variables will be listed in numerical fashion and not in intelligable
numonics. I can not and have no desire to understand interpreted HEX
to ASM even for code written by me, myself, and I.
Here is one of the following that I would do. Make my own code from
scratch. Else, go with an ancillary device. Add another PIC with just
enough code to process the few operative fuctioning keys of the keypad.
This extra PIC will share the LCD controll lines through address buffers.
True, I know I know, no need to tell me about that. Seems drastic
indeed.
I big you good luck with decifering upto 1k of anothers interpreted code.
