Hello, You could upload the firmware directly instead of reverse engineering. Especially when you decide to use same hardware series. I will write the code for this purpose. Best Regards, Khamid

Is it important for you to decode the firmware? I just checked the schematic and can see the project is pretty straightforward, I need you to tell me what you expect from the ATMEGA, and I can do the firmware for you .. anyway if you insist to decode the hexadecimal data, I have no problem, I have already worked a lot with microprocessors and assembly.

I have worked in programming atmel micros in assembly for a long time and I have also had to retrieve code from .hex. I think I can be your best candidate, since as it is my first job as a freelance I can offer less price
