AM5716: Can we use GPtimer to capture PWM input via enable Capture mode?

Zekun Bai

Part Number: AM5716

Tool/software:

I searched in TRM and find ECAP and timer can be used for capture PWM. My customer board have no ECAP pin usable, so only GPtimer can be used for this case.

GPtimer have a Capture mode that can be used for this.

Do we have a example or any guide that can be referred for this case? Thanks

Hello Zekun,

Not sure if we have any examples of this. I will take a look.

What software is being used?

Hi Josue

We use RT-Linux SDK 9.2. Do you have any ideas?

Zekun,

As far as I know there is no existing examples of this usage, I believe this is a feature that has not been implemented before.

Best,

Josue

Hello Zekun,

There is not an example internally for this either.. See the following post:
