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?

If you're using the default CC1000 stack, connect your app to the CC1000Control interface provided by CC1000ControlM and call CC1000Control.TuneManual(868000000). The mote may have trouble working at that frequency, but I think I've gotten some of mine down to around 855 MHz.I also recommend downloading the newest CC1000 stack located in the TinyOS 1.x CVS at /contrib/rincon/tos/lib/CC1000Radio. You can then edit your Makefile to include the directories in the /tos/lib/CC1000Radio library, overriding the default /tos/platform/mica2 CC1000 stack without breaking TinyOS. The advantages this new stack has over the old one are:* Measured 21% more throughput, even on the same baud rate.* Better squelch algorithm for finding the noise threshold.* Better architecture makes it easier to understand and hack.* Smaller size (7% decrease in ROM, 12% decrease in RAM)* Auto-recalibration of the radio, every 8 hours by default, for outdoor applications* Ability to double the default baud rate to 76.8 kBaud (not compatible with some motes)* Joe and Jason's pulse-check implementation - instead of checking for preamble bits on
wakeup, check the RSSI reading on wakeup before the radio is fully in active mode.
35.5% increase in mote lifetime on power mode 8 (4.376 mAh/day or less, a 35.3% decrease!)
It can go lower if you adjust the microcontroller as well to use the internal oscillator.
Uisp with --wr_fuse_l=c4 (?) (needs verification)

May I know how to program the 916MHz mote to 868MHz? Please help, it is urgent. Thanks. :)
