strange question?

think i know the answer
does anyone have a way to backward program a pic
ie convert hex to asm to pb
never hurts to ask

have a nice sunday

If the program was written with the use of a compiler like PBP or C then it is impossible te get the source back. And when the fuses are set for security then you can not read the program of the chip.

Most of time, loading the .Hex in the MPLAB program window permits to have a very good idea of the program ... and also to modify it somewhat !!!

BUT you must read ( and understand ... LOL ) assembler !!!

No hope for reading it into "High level" languages ... Thanks God !!!

just have way to many ver of programs, not sure which one is in the chip

got enough problems with following my own with out trying to fiqure some-else

like. i said have many trys at programs not entirely sure which one i am using

thanks' beside like the other person said it real easy to lock you hex files in the pic

have not done this on my own

Hi Jack,
If it's your own code, then use your programmer to read the hex file and compare to the hex files for each of your versions.
JS

Worth A Try

There is one very expensive way how to read protected data - Laser cutter + electronic microscope

Hi,Therian

For the C series ... there was a very simple method just changing the config settings !!!

never tried with F series ... WHY ???
