The .cbp file is a Code::Blocks IDE project. It probably requires some adaptions, as it includes some paths to a local installation of avr-gcc, avr-binutils, avr-libc... This was done on a linux machine btw. Windows users will have to do some more work. It should be compilable in AVRStudio4 + WinAVR as well (using external Makefile). Precompiled: ATtiny2313.hex fuse settings (internal 8MHz RC oscillator + 2.7V brown-out reset): lfuse: 0xE4 hfuse: 0xDB efuse: 0xFF
