PWM duty setting

[air]

 Hello,

I control buzzer using below API.

I want to know the maximum value of  period_in_us.

 Thanks.

****************************************************************************************************************

#define APP_PWM_DEFAULT_CONFIG_1CH(period_in_us, pin) \
{ \
.pins = {pin, APP_PWM_NOPIN}, \
.pin_polarity = {APP_PWM_POLARITY_ACTIVE_LOW, APP_PWM_POLARITY_ACTIVE_LOW}, \
.num_of_channels = 1, \
.period_us = period_in_us \
}

Hi,

The timer frequency (prescaler) is set depending on the period, so I expect it is quite long. If you ever need so long periods that it is relevant, then I suspect the Low-power PWM library would be more suitable.
