PIC Micro Controller Dissassemblers

Use the IMPORT function of MPLAB found under the File menu to import your code as hex. You can then view the ASM listing in the Program Memory window.

If the program doesn't have the chip listed, add your own. It will automatically be included each time the program starts. It doesn't support 17Cxxx or 16xxxx chips with checksums. It's free.

http://www.geocities.com/dinceraydin/pic/djdasm/djdasm.html Dincer Aydin [dinceraydin at altavista.net] wrote an assembler for the 16F84 PIC micro using JavaScript. It is supposed to run on any JavaScript 1.1 capable browser. (tested on Opera 3.6x, MS Explorer 4.x/5.x, Netscape Navigator 4.x - including Linux versions). It does not disassemble eeprom data and config bits. It has colorized HTML output.
"picdis18" by Claudiu Chiculita is a Microchip PIC 18 Disassembler written in Python. http://www.etc.ugal.ro/cchiculita/software/picdisasm.htm
PICDIS-LITE PIC Disassembler And Hex File Tool reads several different HEX file formats. From "Joe's Cat". (Linux and Windows versions) http://www.joescat.com/micro/picchip.htm

(FIXME: Many simulators also have built-in disassemblers. Should we list such software here on the "dissassemblers" page, over on the simulators.htm page, or both? )
