How do I write to my motor driver?

Development Boards MicroMod

I currently have a Serial Controlled Motor Driver

http://www.sparkfun.com/commerce/produc … ts_id=9571

and the AVR Pocket Programmer

http://www.sparkfun.com/commerce/produc … ts_id=9825

I successfully connected the two and got it working in AVRDUDE, the problem Im having is that I want to update the firmware on the motor driver with a modified version. The firmware comes with three files: a main.h, main.c and a makefile. From what Ive read I need to make it into a hex file in order to write it to the board. How do I go about doing this? This is my first experience with AVR programming so any help would be greatly appreciated.

Thanks

the .h file is the header file. The .c file is the actual C code file. You could use something like AVR GCC to compile them into a .hex file. You then take AVRDUDE and push it to your microcontroller. There is probably a lot more detail that could be given on this but for now, maybe this can get you going.
