Hi,
Sure thing, let us take for instance the Alarm32khzC component which should
provide the interface Alarm<T32khz,uint32_t>.
The precision_tag (T32khz) describes number of clock ticks per second that
is:
For TMilli it is 1024
For T32khz it should be 32768
... and so on
I am thinking of if as if it was a smallest countable amount of time which
might be archived using this Component.
Assuming that I execute the following code:
//..... Application file (with wiring) :
components new Alarm32khzC() as Alarm; // provides Alarm<T32khz,uint32_t>.
App.Alarm -> Alarm;
//..... App component file :
// [...]
uses interface Alarm<T32khz,uint32_t> as Alarm;
// [...]
event void Boot.booted() {
call Alarm.start(10000);
}
// [...]
async event void Alarm.fired(){
call Leds.led0Toggle();
call Leds.led1Toggle();
call Leds.led2Toggle();
}
Leds should be "on" almost immediately after start of the mote ( to be exact
after 10000/32768 [s] + small delay for reaction). It is not the case, they
are turning on after [!] ~10 second, as if it was working with precision_tag
TMilli.
Regarding the tutorial, I was going through it but I admit it was quite
brief. Maybe I miss something very platform specific.
All in all, thank you for replay. I am looking forward for comments.
