I want to measure a pulse width. And I used TIMH0 to capture the pulse.
When the capture finished, I use "DL_TimerH_stopCounter" and "DL_TimerH_disableInterrupt" to stop the counter.
Then use "DL_TimerH_getCaptureCompareValue" to calculate the pulse width.
So my question is:
1. How to restart the counter? To capture the next pulse.
2. How to calculate the pulse width? What's the Arithmetic relationship between compare value and pulse width.
Hi Zhou,
Thank you for your help. Now I know how to calculate the pulse width.
But I found that the TIMH0_IRQHandler has some problems.
Because the interrupt can be only executed for 2 times. (Using the breakpoint when debug)
So I am not sure whether the config is right. There maybe exsits other problems?
I will show my config in pic.

Please see this chapter:
The Timer will not stopped when the code hit the breakpoint. You may need to change the configuraiton in software. Maybe this is the problem.
