Activating PWM and 4MHz clock signal from GPIOhttps://devzone.nordicsemi.com/f/nordic-q-a/29663/activating-pwm-and-4mhz-clock-signal-from-gpioHello I am using nRF51822 Nordic controller, SDK 9 and S130 Soft-Device. I have used to generate a 1 KHz PWM signal successfully using timer 1. And generating a 4 MHz clock signal from GPIO using timer 2 also succeeded. Each trial alone Buten-USTelligent Community 13Tue, 23 Jan 2018 15:20:42 GMTRE: Activating PWM and 4MHz clock signal from GPIOhttps://devzone.nordicsemi.com/thread/117770?ContentTypeID=1Tue, 23 Jan 2018 15:20:42 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30b8f36d-841c-44d5-ba71-82b70141ffc5MartinBL<p>The app_pwm library uses PPI channels, and it is likely that you overwrite its configuration when you configure the PPI registers directly in your ppi_init() function. Instead of configuring it directly you should use the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/hardware_driver_ppi.html?cp=4_0_0_2_7">PPI driver</a>. That will take care of assigning free PPI channels for you.</p><div style="clear:both;"></div>RE: Activating PWM and 4MHz clock signal from GPIOhttps://devzone.nordicsemi.com/thread/117769?ContentTypeID=1Tue, 23 Jan 2018 11:20:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed3c07e9-8481-40f6-80f7-e565734fd27dSteve<p>The pwm block is a copy of an example supported in the sdk examples file</p><div style="clear:both;"></div>RE: Activating PWM and 4MHz clock signal from GPIOhttps://devzone.nordicsemi.com/thread/117768?ContentTypeID=1Tue, 23 Jan 2018 10:31:03 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11c20659-5bbf-4a5b-8565-23ef0abdc265MartinBL<p>Hi,</p> <p>How are you generating your PWM? Can you post some code (you can edit your original question)?</p><div style="clear:both;"></div>
