https://devzone.nordicsemi.com/f/nordic-q-a/32749/a-question-about-pwm-of-nrf52832Hi: I output a PWM channel in 16kHZ,i found that when i set the duty cycles 50%,my tft screen(i2c) display at a very slow speed,and it will be OK when i set duty cycles 10% or 90%.when i set the frequency lower then 10kHz,it is OK too.

Are you using the PWM do dim your screen, but it doesn&#39;t work with duty cycle at 50%? What screen model do you use?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/125920?ContentTypeID=1Mon, 26 Mar 2018 09:40:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:44210d3a-4762-4f6c-bdea-3b5b6a24d630Turbo J<p>That sounds like a job for an oscilloscope...</p><div style="clear:both;"></div>
