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 !!!

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.

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 ???
