S32K3 frequency measurement on FLEXio

[Tobias12]

Hi all,

I am looking for a possibility to measure frequencies on the S32K FLEXios. Unfortunately EMIOS has not enough channels for my application.

The goal is to measure frequencies up to 20kHz.

Is it possible to use the FLEXios or is there another option I don't see?

Thanks

Tobias

Hi Tobias,

There are just EMIOs and the FlexIO for HW input capture.

The FlexIO input capture is used in emulated SENT receiver (RM, 73.6.8 SENT receiver).

There are SENT receiver examples in RTD, so you can refer to that.

Regards,

Daniel
