Using PWT module

ricardcomas — Mon, 30 Jul 2018 12:39:10 GMT

Hi everyone, i don't get PWT work,i must initialize module and get result of PPW with function PWT_PDD_GetPositiveWidth(PWT_BASE_PTR), REALLY?¿ o don't need interrupts here, i need get value by polling, i found this code:

Its look like a lot basic, how can use correctly?¿

I need get positive pulse width by polling,so i tought only init component and get its value.

Have a sample code somebody?¿

thanks so much

Hi Ricard Comas,

You may need to polling check the state of PWT_R1[PWTRDY].

PWT_PDD_GetInterruptFlags function can be used.

I don't have the PWT sample code using Processor Expert. But you can find the PWT_demo in FRDM-KEXX-Driver-Library-Package(...\FRDM-KEXX-Driver-Library-Package\ke_drv_lib\build\iar\ke06\PWT_demo)

For more detail, please read "27.4.2 Edge detection and capture control" of MKE04P80M48SF0RM.

Best Regards,

Robin
