Hi,

According to the document for TOSSIM in Tinyos-2.x, it only supports micaz now and their implementation is under the "sim" directory.

[EMAIL PROTECTED] tos]$ find . -name sim
./platforms/micaz/sim
./platforms/micaz/chips/cc2420/sim
./platforms/mica/sim
./chips/atm128/sim
./chips/atm128/pins/sim
./chips/atm128/spi/sim
./chips/atm128/timer/sim

I thought ./platforms/micaz/chips/cc2420/sim is the implementation for cc2420, but the file SimCC2420C.nc under ./platforms/micaz/ chips/cc2420/sim is without implemenation (see the following).

Any idea why it is so? Where can I find the Tossim implementation for cc2420 in Tinyos-2.x? Many thanks.


There is currently no CC2420 simulation implementation: TOSSIM uses a packet simulation. The micaz TOSSIM platform simulates the atm128 timers down to the HPL (registers), but active messages use a simulation-specific implementation.
