Thanks. **************************************************************************************************************** #define APP_PWM_DEFAULT_CONFIG_1CHen-USTelligent Community 13Wed, 22 Aug 2018 12:23:28 GMThttps://devzone.nordicsemi.com/thread/145315?ContentTypeID=1Wed, 22 Aug 2018 12:23:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:daa3ec83-d7d3-427b-8caf-51bae65bd59fEinar Thorsrud<p>Hi,</p> <p>The timer&nbsp;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 <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.0.0/lib_low_power_pwm.html?cp=4_0_0_3_27">Low-power PWM library</a>&nbsp;would be more suitable.</p><div style="clear:both;"></div>
