https://devzone.nordicsemi.com/f/nordic-q-a/17119/rgb-led-pwm-driver-with-nrf51Greetings, Here&#39;s an implementation of controlling the color of a RGB LED with a TIMER of nRF51. It works well most of the time, although it inverts polarity kind of randomly, especially when the r,g,b values are low. We know of the issue of PWM inversionen-USTelligent Community 13Thu, 26 Apr 2018 06:55:43 GMThttps://devzone.nordicsemi.com/thread/129864?ContentTypeID=1Thu, 26 Apr 2018 06:55:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11570779-a83d-4523-99d2-a991c2548e99shivali singh<p>CAN YOU SEND ME CODE,</p> <p>shivali.chauhan791@gmail.com</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/65701?ContentTypeID=1Tue, 18 Oct 2016 08:19:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f9dd5494-3bb3-419a-9d82-2eff93f98f93Ole Bauck<p>The problem may be that you clear the timer before you stop it. If you get interrupted after clearing the timer and before stopping it, the timer counter value may go past the new CC value, and you will have inversion.</p> <p>Stop before you clear instead:</p> <pre><code>rgb_timer_stop(); rgb_timer_clear(); </code></pre><div style="clear:both;"></div>
