Here are three disassemblers for PIC Chips.

The first disassembler has been designed by Mikado:

• Create a folder name it Disassembler:

Disassembler

• Download Disassembler.zip file and place it in Disassembler folder.
• Unzip the file.
• Click on Mikado3.3.3e.exe and “send to desktop” (create a shortcut).
• Rename the desktop icon “Disassembler”
• Place the .hex file you wish to disassemble in the Disassembler folder.
• Click on the “Disassembler” icon on your desktop.
• The disassembler program will load
• Select and click on: HEX File to ASM file for MPASM
• Click on OPEN for the location of your .hex file and insert the address.
• Click on OPEN for the Include File and load P12F629.INC
• Select AUTO
• Select NEXT
• Select CLOSE
• The result of the disassembly will be placed in the Disassembler folder.

The second disassembler has been designed by Norbert Hagemann.

The third disassembler is the one that works best:

It is: DISASM.zip This file will unzip to DISASM.EXE.

You also need the following two files:

• CMDIALOG.VBX

• VBRUN300.DLL

• Place them all in the same folder and click on DISASM.EXE

• Load the .hex file you want converted to .asm and the result will appear in the window.
  Save the file as “-2.asm” and it will be saved in the same folder.
