SENT TX using FlexIO on S32K324

Hi everyone,

I am trying to implement the SENT procotol on S32K324. There is an example for SENT RX on FlexIO inside the IDE:

But, I do not see SENT TX. I want to use FlexIO for this. Is there any example project on this topic? I would appreciate this.

Thanks in advance.

Hi @ilx123,

Usually, the SENT signal is usually transmitted by an external sensor and received by the MCU, those are the only demos we provide. However, you can use the eMIOS component if you want to implement the SPC Protocol. Here are some community related posts:
