Hi,all,
I am using Crossbow's iris mote. I want to send current system time in the
mote.
I tried to use the Time interface in SimpleTimeM. However, I always get zero
value for the system time.
This is the interface:
interface Time {
/**
* get current time. Return it in tos_time_t structure
**/
async command tos_time_t get();
/** get the high 32 bits of current time */
async command uint32_t getHigh32();
/** get the lower 32 bits of current time */
async command uint32_t getLow32();
/** get clock phase offset since last clock tick
* in unit of micro-seconds.
**/
async command uint16_t getUs();
}
In my function, I write:
atomic a=call Time.getHigh32();
atomic b=call Time.getLow32();
However, I always get 0. I am pretty sure that the problem should be in
'call Time.getHigh32()'.
So how can I fix this problem. Why I always get the 0 of the system time?
Thanks very much!
