pwm can not work with softdevice, when i use s110(v7.1) , sdk 6.1

bob

Hi Nordics,

I copy pwm sample code into my proximity project, to drive a buzzer .

I init pwm before softdevice. but, once "SOFTDEVICE_HANDLER_INIT" is excuted, the buzzer pin no longer toggle.

My question is , softdevice use TIMER0, my pwm use TIMER2, it seems that they are independent two modules. why pwm not working ?

Many thanks !

Bob

    If you are using the code in pwm_example it may be because the example access some registers that are restricted when using SoftDevice, more specific NRF_CLOCK and NRF_POWER, see here. You will need to use sd_clock_hfclk_request and sd_power_mode_set instead, although these are not necessary (pwm will work fine with RC clock and not constant latency mode).

    This PWM example has a high possibility of inverting when using it with a SoftDevice. I will recommend to update to our newest SDK to use the newest driver which does not have this bug. You will need to update the SoftDevice also.
