Calculating Function Run Time

[DaSi_281136]

Hello,

Is there a way to to determine the run time of a function?
Normally I'll toggle a pin at the beginning and end of a function and measure with a scope.

That's obviously not a perfect solution as it includes the time to toggle the pin.

I figured there was a way to do this via Creator or during a debug run.

Thanks

DaSi,

You didn't mention processor type.

On PSoC4 and PSoC5  you can use a custom component StopWatch to measure elapsed CPU clocks

And for PSoC6

Thanks for the reply.

I'm using a PSOC5LP.

I'll take a look at using the stopwatch.

I'm hoping to the be able to get nanosecond resolution.

The StopWatch accuracy is 1 BUS_CLK, which at 80MHz translates into 12.5ns.
