Hi,

Kind regards,

Hi Folks,

Is there any updates on this? We are planning to use PWM input with nRF52832 and hoping to use pwm_pin_capture_cycles() for the same.

Is it supported with latest 1.8.0? If not, what could be the alternate to this?

Thanks!

Hi,

The nrf port to the zephyr pwm driver does not have support for CONFIG_PWM_CAPTURE:

Any calls to functions exposed from CONFIG_PWM_CAPTURE will return ENOTSUP.

Kind regards,

Håkon
