[Tinyos-host-mote-wg] [Tinyos-2.0wg] Generic preprocessing

[Cory Sharp]

I have a number of similar modules that handle hardware events, let's
call them AlarmB0C, AlarmB1C, etc.  I'd like to write in nesC "new
AlarmC()" and have it return the next available module.  Because each
module is handling hardware events, I'd like unused modules to never
be pulled in.  Does anyone have an idea on how I can do this?

I'm currently doing this below, but the problem is that all of the
interrupt handling code is included (unneccessary bloat), even if I
only call "new AlarmC()" once.  My gut reaction is to want use #if
processor directives to remove any unreferenced AlarmBXC modules. 
But, of course, this isn't exactly possible.  Any ideas?

Thanks, Cory


module AlarmMapC {
  provides Alarm[uint8_t id];
} implementation {
  components AlarmB0C, AlarmB1C, AlarmB2C, AlarmB3C;
  Alarm[0] = AlarmB0C;
  Alarm[1] = AlarmB1C;
  Alarm[2] = AlarmB2C;
  Alarm[3] = AlarmB3C;
}

generic module AlarmC() {
  provides interface Alarm;
} implementation {
  components AlarmMapC;
  enum { ALARM_ID = unique("AlarmMapC") };
  Alarm = AlarmMapC.Alarm[ALARM_ID];
}
