[Tinyos-help] How to create an event?

[Muhammad Azhar]

Hi all,

   I'm using TinyOS-2.0 and I'd like to create an interface (assume all the 
necessary wirings have been done) whereby a certain event will cause a 
node's timer to fire periodically for 1s.  However, after 1 minute, I'd like 
to signal to the application program that 60 seconds have passed.  Can I get 
some pointers on how I can go about doing this?  I am not so sure if it 
should look something like this:

=====================================================
module someModuleP {
  provides { //all the interfaces it provides }
  uses { //all the interfaces it uses }
}
implementation{
//I declare a new event in this module
event void oneMinPassed();
..............
//from Timer interface
event void TImer.fired(){
...
  if(counter%60 == 0) {
    signal oneMinPassed();
  }
...
}

}
==================================================

   Did I miss any step?  Many thanks for your help.

Regards,
Azhar
