How to fit the library to an other microcontrôler ?

First, be sure that you have at least 40K bytes of program memory, and about 2k of RAM.

You have to create target specific interface to HW resources. Take model on bundled interfaces provided in drivers/ and create your own interface. You also have to update Makefile.in files for target specific cflags and options. Chose -targer= configure switch to compile your specific interface.

You are welcome to contribute-back your own interfaces ! Other Canfestival users will use it and provide feedback, tests and enhancements.
