PWM peripheral defaults pins to 0 when I want them to invert and default to 1https://devzone.nordicsemi.com/f/nordic-q-a/111609/pwm-peripheral-defaults-pins-to-0-when-i-want-them-to-invert-and-default-to-1Hello, I am using the nrf5340 on some custom hardware, and I am using 3 LEDʻs and running them with the PWM0 peripheral to fade and blink and indicate states for the firmware. The LEDʻs are driven as active-low, and I am using the PWM flag PWM_POLARITY_INVERTEDen-USTelligent Community 13Wed, 29 May 2024 17:42:43 GMTRE: PWM peripheral defaults pins to 0 when I want them to invert and default to 1https://devzone.nordicsemi.com/thread/486508?ContentTypeID=1Wed, 29 May 2024 17:42:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e7a3f4f9-f616-4a11-a9c4-65ddf653cc7fRobert de Brum<p>This worked thank you</p><div style="clear:both;"></div>RE: PWM peripheral defaults pins to 0 when I want them to invert and default to 1https://devzone.nordicsemi.com/thread/486355?ContentTypeID=1Wed, 29 May 2024 09:24:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dfff937b-be8a-4cdd-8575-97df94ca54e6Sigurd Hellesvik<p>Hi,</p> <p><a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/config_and_build/configuring_app/hardware/pin_control.html#pin-control-in-nrf">Pin control docs</a>: </p> <p>&quot;<code><span>nordic,invert</span></code>: Invert <span>pin</span> polarity (set active state to low).
