AVR Programming quick guide
Quick guide useful for first approach or as a reference for commands, pinning, etc…
The matter: upload a compiled code file (.hex) into the avr's flash memory.
Use a Makefile to do all the work. Download it here.
In the makefile:
- change/add source files;
- change your project name;
- change part name (for example atmega16);
- change programmer type and port.
Use make to compile, make hex to generate firmware in the format read by the programmer, make writeflash to program the AVR.
I have also added make fuse that should be adjusted in the Makefile, to write the fuse byte(s).
Notes
Atmega64 : remove compatibility flag when programming, otherwise lot of registers won't work and the code will crash.
i.e. extended fuse bits should be 0xFF
avrdude -p m64 -P /dev/parport0 -c stk200 -U efuse:r:-:h
will output 0xfd, so let's do
avrdude -p m64 -P /dev/parport0 -c stk200 -U efuse:w:0xFF:m
