https://devzone.nordicsemi.com/f/nordic-q-a/22230/why-is-my-pwm-is-modulatedWhen I set the PWM driver for very low frequency i can see how it blinks, the thing is that it always blinks where it&#39;s more or less 70% of the time ON and 30% OFF . When I change the duty cycle say for 10% , it will not change the duration of theen-USTelligent Community 13Thu, 08 Jun 2017 10:49:15 GMThttps://devzone.nordicsemi.com/thread/87351?ContentTypeID=1Thu, 08 Jun 2017 10:49:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f5c9a88d-a5d0-4968-a9f2-b837193e6c0cFormerMember<p>I guess you are using the pwm_simple exmaple from <a href="https://devzone.nordicsemi.com/question/137430/is-there-a-simple-example-how-to-set-a-pwm-driver/">this</a> thread.</p> <p>If you route the output from the example to another pin than an LED pin, you will see (using a logic analyzer) that the output has the correct duty cycle.</p><div style="clear:both;"></div>
