Hello,
I am implementing ECC Arithmetic on micaz motes with tinyOS-2.X. I want
to mesasure the timing efficiency of my methods. I want to get the time
just before calling the method and just after finishing the method.
There was a component called SysTimeC in tinyOs-1.x and I think that
could be used for my purpose, but SysTimeC does not exist in tinyOs-2.X
any more.
Which component should I use in tinyOs-2.X to be able to get as much
precision as by using SysTimeC in tinyOs-1.X.
Thanks a lot for your help
I was going to suggest CounterMicro32C, which isn't guaranteed to
exist on all platforms. It turns out it doesn't exist on msp430-based
platforms ;-) (though it would be fairly easy to add I think, based on
Msp430CounterMicroC). It does exist on mica family platforms.
Note that on mica motes, CounterMicro32C stops counting while the mote
is asleep (otherwise the mote wouldn't be able to sleep ;-)). Also
it's not exactly counting microseconds (mica's run at 7.XX MHz, so the
time unit for CounterMicro32C is 7.XX/8 us).
