Do you use TOSSIM or real motes ?
in TOSSIM getlow32() doesn't work,
it always returns 0.
If you use real motes you probably
must search specific timers for your platform (in \platform\NAME\ directory)

Subject: [Tinyos-help] A question about getting the system time
Hi all,
I use tinyos to program my sensor motes. Because I want to measure the
delay of the packets, I have to record the current system time.
The part of my program is the following:
command result_t IntOutput.output(uint16_t value)
{
int aaa;
uint32_t time = call Time.getLow32();
IntMsg *message = (IntMsg *)data.data;
if (!pending) {
pending = TRUE; atomic {
message->src = TOS_LOCAL_ADDRESS;
}
if (time == 0) call Leds.yellowToggle();
aaa = (int)time;
message->val = aaa; if (call Send.send(TOS_BCAST_ADDR,
sizeof(IntMsg), &data))
return SUCCESS;
pending = FALSE;
}
return FAIL;
}
I use the LED to arbitrate the value of time (which is used to record the
current time)
if (time == 0) call Leds.yellowToggle();
but I find that time is always 0. I don't know why. Can anybody give me
some suggestion or advice? Thanks.
Best wishes,
Ferris
