FTM input capture mode, CnV value

[perryjagger]

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
