The basic trouble is that including the same piece of software into different

Kind of hard to understand from staring at what you've provided.
Something that might help would be to examine the resultant output of nesc.

Hello,
In a TinyOS application, is there a trick to find the wiring of a particular
singleton component?
e.g. If I want to know what is wired to the Msp430SpiConfigure interface used
by Xe1205SpiNoDma0P in the BlinkToRadio app?

Its all in knowing where to lookAnd what the thing looks like.
There maybe a way to do this using the docs feature. Doing something like.

that can be accessed using a browser that presents a graphical
representation of how things are wired.

Thanks Eric, I'll try that.
As far as I can see, the make platform docs (nesdoc) output only displays
the interfaces and internals of each component. i.e. if I look at a
configuration I can see if it uses Xe1205SpiNoDma0P and how it wires it, but
not the other way around.

Hi,
I just tested the following snippet on TelosB, whose output is also listed.
int8_t a, b;
a = -1;
printf(%d\n, a 1); //-2
a = -127;
b = a 1;
printf(%d\n, b); //2
printf(%d\n, a 1); //-254
b = a 1;
printf(%d\n, b); //-64
So the right shift is arithmetic.

I think the size of the executable depends on how you used the logging
component in your TOS applications. The reasons are nesC compiler does
aggressive inlining and by default, TinyOS build system optimizes for
code size (-Os is passed to C compiler).
You can try turning off inlining and
Hi Lue,
Did you check the number of blinks on your motes and count the number of

Maybe you are getting the right number of messages but they are not properly
labeled from 0 and from 1. This would explain why you get the same
result with any node as root.
If that doesn't help,
Hi Breno,
i was suspecting the same thing, so i purposely changed the data message for
other node. example, node 0 will send 0xCAFE to root and node 1 will send
0xAAA. at the end, UART only displayed 0xCAFE, which is from node 0 only.
So, i bet it is not the case here.
