[Tinyos-help] About Events and Commands

[Aditya Bhave]

The SendMsg.send() coomand is actually implemented in AMstandard.nc. You
must be reading Chapter 4 of the tutorials.  Look at the wiring of
SendMsg.send. It is wired to GenericComm. This in turn is wired to
AMStandard which in turn uses several low level system modules wherein the
individual bits are actually transmitted over the radio.

My advice is unless you want to change the tinyOS functionality, there is no
point in trying to figure out where the functionality is actually being
implememnted. Having a higher level understanding of how send and receive
work and how they should be used is sufficient to build applications.

There is a very very deep tree of modules in tinyos. Most of the system
modules are in the tos/lib or tos/system folders.
