https://devzone.nordicsemi.com/f/nordic-q-a/6550/pwm-library---glitch-definition-statusWhat exactly are the &quot;glitch&quot; issues with the PWM master library ? I see there have been some recent updates, but no clear indication as to what issues remain or have been resolved? I take it the 4 channel (non-glitchless?) version still glitches or hasen-USTelligent Community 13Mon, 20 Apr 2015 14:57:56 GMThttps://devzone.nordicsemi.com/thread/22870?ContentTypeID=1Mon, 20 Apr 2015 14:57:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c7b98536-efb5-40a6-846b-faaf4206b453ovrebekk<p>Hi</p> <p>The naming in the latest version is probably a bit misleading, as both drivers should now be glitchless.</p> <p>If you need 4 channels without glitches you should use the latest version of nrf_pwm.c. The drawback of this driver is that it uses the timeslot API for the SoftDevice, which limits the maximum update frequency of the PWM. If you don&#39;t use a SoftDevice the timeslot API is not needed, but the PWM will require to run at the highest interrupt priority when updating the duty cycle.</p> <p>To minimize overhead when using the new nrf_pwm.c driver it is recommended to update several channels in a row using the nrf_pwm_set_values(..) function, rather than updating each channel individually.</p> <p>To summarize, nrf_pwm.c should work well now without glitches, so please try that out. If you do experience any issues please let us know :)</p> <p>Regards Torbjørn</p><div style="clear:both;"></div>
