MICROCHIP PIC Programmer - Reverse Engineering

I have a project based around an PIC16F877A microcontroller that I want to patch/edit the firmware for. I do not have the source code.

This project is a small board that reads some keys and sends commands to a computer (Linux Software) via USB port.

I only have the .HEX file / .BIN file and NO source code.

I have too: Gerber files, BOM list and electronic schematic of the board.

I want to make updates to the product:

- Change the firmware to a new board (new existing board);

- Understand and decode the contents of the PIC EEPROM memory;

- Understand and decode the communication protocol between the PIC to the PC (software);

It would be very useful to convert the .HEX file to C or Assembly organizing the code and making comments.

Doubts send me a private message.

Habilidades: Montagem, Programação C, Eletrônica, Microcontrolador

It is not easy to convert hex to C... What we can do is that if you can provide us the functionality of the board fully, we can develop the same program from the scratch.. I have 12 years of experience in PIC16F877A Mais

First thing is PIC16F877A is not an USB ready MCU so it must have been working as USB1.1 protocol and simulated USB connection to linux computer. Why dont you use PIC18F4550 which is Full speed USB 2.0 MCU and drop in Mais

Hello. Thanks for inviting me. First of all I have to see schematic and flash-eeprom dumps if you please. After decoding the protocol and eeprom it is better to write your own C firmware I think. I have such a chips in Mais
