Daniel,
In general, TOSSIM doesn't simulate all mote hardware. There are
functions which have not been implemented, or been implemented
differently in simulation than in the real hardware. (I would bet one
such case is here:
/opt/tinyos-2.x/tos/chips/atm128/adc/Atm128AdcC.nc:65) One example is
the printf function of tinyos. In hardware, there is a buffer that
holds the printf string, and only automatically flushes it when the
buffer is more than half full. If you want an immediate flush, you need
to use the function printfflush(). In TOSSIM, printf always flushes
immediately, and printfflush is not defined.
I found that a lot of times, i had to write a lot of compiler if
statements with:
#ifndef <Some custom define stating that we are compiling for TOSSIM>
...
#endif
or
#ifndef ...
...
#else
...
#endif
If you want to work with both the real hardware and tossim.
Just a word of warning, do not use "TOSSIM" as the define variable
because it can muck up the build in other places that use it for a
different purpose.

Hi,
I ´m doing a job in TinyOS 2.x installed Xubuntos. I am working on
MicaZ platform that uses the component TempC MTS300 sensor, but when

The same occurs with the example
"/apps/tests/mts300/PhotoTemp/Oscilloscope"
Do I have a configuration problem?
Thanks and regards.
