https://devzone.nordicsemi.com/f/nordic-q-a/17306/how-to-operate-pwm-and-softdevice-at-the-same-timeI`m trying to operate PWM and soft device at the same time. I have to make 4 Mhz using PWM block so I checked the PWM driver. There is no problem when using peripheral/pwmdriver. However,when I applied pwm driver to ble_app_uart example, pwm driveren-USTelligent Community 13Tue, 25 Oct 2016 15:24:34 GMThttps://devzone.nordicsemi.com/thread/66498?ContentTypeID=1Tue, 25 Oct 2016 15:24:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b72d2dbc-45f1-4721-b0a1-43d0b82cf693Stefan Birnir Sverrisson<p>Hi Mac</p> <p>The top value has minimum value of 3. That is stated in the PWM <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pwm.html?cp=2_2_0_46_4_6#register.COUNTERTOP">COUNTERTOP</a> register. If you want to make 4MHz square wave, you can do that with TIMER+PPI+GPIOTE, similar to what is done in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/nrf_gpiote_example.html?cp=4_0_0_4_5_10">gpiote example in the SDK</a>, just with higher frequency.</p><div style="clear:both;"></div>
