Hi~daniel??
First of all , Thanks so much for your fast reply.
I don't want to bother you. But I have a further question about this.
Actually, I've got the point of yours.
The fact is I need to parameterized interface. and I need to know how to use it.
Let me explain the why I need it.
enum{AckOne=0,AckTwo=1,...};
configuration A{
}
{ components TimerC, ...,..., ;
BeaconMoteM.Ack[AckOne] -> TimerC.Timer[unique("Timer")];
BeaconMoteM.Ack[AckTwo] -> TimerC.Timer[unique("Timer")];
BeaconMoteM.Ack[AckThree] -> TimerC.Timer[unique("Timer")];
BeaconMoteM.Ack[AckFour] -> TimerC.Timer[unique("Timer")];
}
module A{
uses interface Timer Ack[4];
}
Originally, I need parameterized interace with Timer interface type.
I want to start and stop the timer by Ack[index] indivisually. by not unique
interface instance name one by one.
That's why I need parameterized interface.
The Reference manual of nesC v1.1 says that you can use interface SendMsg
S[uint8_t id ] as a parameter interface
instead of interface X as Y as simple interface.
Is there a way to call start function of the timer by index of Ack[index]. not
acktimer1 or acktimer2.
like these one, call Ack[index].start (.....) or call
Ack.start[index](.........).
I'm not sure that it is enough for you to understand what I want.
Thanks for your reply again.
With regards
