Hi Eric,
The SAM4 is very similar to the SAM3. Shouldn't be too difficult to get it
up and running on it. You will have to enable the compiler flags for
hardware floats if that's why you want to use a SAM4 though.

Nahr,
This is how the radio chip works, and not the TinyOS implementation. This
is how the radio decides if it received a 0 or a 1. TinyOS can only access
the final result, not the actual value used for the soft decision.

Hi,
Fairly simple, the FTSP paper was based on the Mica2 (or was it the MicaZ?)
which has a higher frequency crystal. You can do a similar thing with the
TelosB, but you will have to change some of the code. Search the mailing
list. There were long threads discussing how to do that.

The problem is not in the TinyOS code. The hardware you use (I assume

The EZ430-Chronos is based on the CC430F6137. This is a SoC that
