[Tinyos-help] choosing mica2 operating RF frequency

[Conor Todd]

Holy moly, that's quite different than the CC1000 architecture for the Mica2
in TinyOS-1.1.15!

I'm using the RadioReceiveCoordinator interface for the CC1000 in my app;
can you give me any direction as to how I might switch from the standard
CC1000 stack to the Rincon code?
