Hi,
I started to disassembling ClonePI software. I'm trying to obtain C source code from hex file. Manually converting C code from assembly listing is a slow process. May be in the forum we can do it more easily together. Any help is appreciated.
Original hex file is ClonePI-18.hex, downloaded from www.fandy.front.ru/CPI_PRG_181_18.zip
I'm using Ida Pro V5.1, MPLAB IDE V8.0, HI-TECH PICC-18 V8.30
Here is the first part of C conversion
