Disassembler for PIC16C745

Hi

Does somebody know if it's possible to disassemble an .HEX fil from a PIC16C745?

Try this program.

P.S. i think you can do using the Mplab from Microchip.

You could also try my programmer software WinPicProg, which disassembles various PIC HEX files.

I have tried both, but i get some errors when I try to compile the asm file again with MPLab:

PicDisasm:

Are you selecting the correct device?, although it is possible that the 16C745 setting is trying to use the 12C509 disassembler? - it's been so long I can't remember?.

As I understand it, MPLAB does a crude kind of disassembly as well?.

Yes, I am selecting the correct device and I have also tried to select the 16C765, but it's the same.
I have also tried using the MPlab but it dosen't seem to disassembly. I can only se the program memory, which fx. doesn't have any label so a call or goto is done to an address and not a lable.
