How to change PWM frequency

[yunjoo727]

Hi,

[ Environment ]

- Application: Lifesaver
- Chip Series: nRF52832
- SDK version: SDK14.2.0
- Compiler: Keil V5

We have to keep changing the pwm frequency.

Reinit will cause a delay.

Can I change the PWM frequency without reinitializing the PWM?

Thanks.

Best regards,

Hello, just wanted to add to this post that a sequence of nrf_drv_pwm_uninit() -> nrf_drv_pwm_init() -> nrf_drv_pwm_simple_playback() takes 11.6 us on a target NRF52832 running at 32 MHz, so it shouldn't affect the hearing of the human ear.
