FTM input capture mode, CnV value

perryjagger — Wed, 01 May 2019 16:49:39 GMT

I'm using KV31F FTM1 ch1, FTM2 ch0, FTM3 ch1 as an input capture on both edges. The channels are generating interrupts, however the CnV value is only loading 0's. Is there a required command to start the CNT with input capture mode or a required way to read the Cnv?

Please see attached FTM1 ch1 Initialization code.

Hello Perry Jagger,

I strongly recommend you first check the input capture demo under MCUXpresso SDK.

Download from https://mcuxpresso.nxp.com/en/select ,

it support MCUXpresso IDE, IAR and KEIL.

There is a demo named "ftm_input_capture" under "driver_examles" folder:

Hope it helps,

Have a great day,
TIC
