How to use timer to capture on JN5189

lvdp — Sat, 17 Apr 2021 03:45:10 GMT

Hi:

We need to use the JN5189 timer to capture the width of the PWM. I saw this API CTIMER_SetupCapture() in the SDK, but there is no driver_examples. I don’t know how to use this function. At the same time, the datasheet does not indicate which PIN can be used to timer capture,and which capture channel corresponds to. Can you tell me?

Hi,

The pin description is in chapter 8 of RM. You can refer this link CTIMER to know how to capture.

Have a great day,

Yes, we found the pin description on datasheet later,but I did not find the CTIMER_GetCAPCounter() in the SDK of JN5189

Hi,

You can read the CR register.
