RE: [Tinyos-help] help, strange automatic fired timer!!
Hi,
I do know the problem, but I think you can write any word (Timer o anything)
if you have defined it corretly.
I am sorry I can help you with your previous question.

Re: [Tinyos-help] help, strange automatic fired timer!!
Perhaps you need to pass different strings to unique() in order to get different values out of it? What I am implying is that all three of the timers you wire below may resolve to the same timer because you give them all the same name.

Re: [Tinyos-help] help, strange automatic fired timer!!
I think that it's exactly the other way around. You have to use the same string in very instance so that the compiler knows that they must have different numeric values. At least, that's what I understand from the documentation [1].[1]: http://www.tinyos.net/tinyos-1.x/doc/tutorial/lesson2.htmlConor Todd <[EMAIL PROTECTED]> escribió: Perhaps you need to pass different strings to unique() in order to get different values out of it?

unique() is very cool. From Philip Levis' "TinyOS Programming" v1.0, section
6.2:
"The unique function takes a string key as an argument, and
promises that every instance of the function with the same key
will return a unique value. Two calls to unique with different keys
can return the same value.
So, instead of writing:
MSPSensingM.LedsTimer -> TimerC.Timer[0];
MSPSensingM.SyncTimer -> TimerC.Timer[1];
MSPSensingM.SendTimer -> TimerC.Timer[2];
you do:
MSPSensingM.LedsTimer -> TimerC.Timer[unique("MSPSensing")];
MSPSensingM.SyncTimer -> TimerC.Timer[unique("MSPSensing")];
MSPSensingM.SendTimer -> TimerC.Timer[unique("MSPSensing")];
If you haven't read it, I highly recommend Philip Levis' manual. I believe
the 'official' URL for it is:
http://csl.stanford.edu/~pal/pubs/tinyos-programming.pdf

For TimerC, you cannot. You have to use the same string that is used
in the component to compute the uniqueCount. This is "Timer". Other
components might use different strings. Inside TimerC:
uint8_t queue[NUM_TIMERS];
interfaces/Timer.h:
#define NTIMERS uniqueCount("Timer")
and
NUM_TIMERS = NTIMERS
(the #define is in case you are using a version of nesC which does
not support unique/uniqueCount).

You are completely correct.
You MUST pass the string "Timer" to unique() when wiring to TimerC.
If you pass another string, then two components will both wire to the
same timer. When it fires, they will both handle the event. This is
what is happening.
