Hi,

You should call app_pwm_disable() if you want to stop the PWM signal. This will set the GPIO to the polarity that was configured for that pin during initialization.

hey einer,

i can see that

pwm_update_duty_cycle(0);

is turning led off, but when i interface vibartion motor, still it is vibrating a little.

please recollect my all doubts, and guide me.

thanks

please guide me how to do it, for pwm_driver example.

as i am able to do in pwm_library example by using:

app_pwm_disable(&PWM1);
app_pwm_uninit(&PWM1);

shall i compile the thease function containing source file???

or if there is function available for driver level , pls let me know.

i have tried using :

nrf_drv_pwm_uninit(&m_pwm2);

but its not working for me accordingly.

Hi,

Have you enabled logging in the projects sdk_config.h file? I recommend you copy the relevant parts (defines starting with NRF_LOG_) from another example project that use logging by default, as the sdk_config.h for the PWM library example does not include them.
