My first implementation of the serial interface for the mc13224v was
written in Contiki.
I decided that implementing the serial protocol side is trivial and
Contiki adds too much complexity.
You can see my code here:
http://git.devl.org/?p=malvira/linux802154-serialdev.git;a=blob;f=linux.c
It's only 250 lines or so and very simple.
The hard part about supporting new hardware platforms is dealing with
the hardware: the radio, the UART, or doing USB->serial in the case of
a chip that has USB builtin. Contiki doesn't help much with this.
