https://devzone.nordicsemi.com/f/nordic-q-a/7904/nrf51822-pwm-losing-eventsHello, I am using Timer_2 with two CC registers configured, 2 PPI channels (one for each CC register in the timer), and one GPTIO_TE to make a PWM to control dimming on an LED. The PPI channels are configured as follows: // Configure PPI channelen-USTelligent Community 13Tue, 30 Jun 2015 17:09:08 GMThttps://devzone.nordicsemi.com/thread/28261?ContentTypeID=1Tue, 30 Jun 2015 17:09:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0b858a35-566c-47c4-98e7-5e8a275f660cLucas<p>I guess the code Radosław Koppel posted is the solution? I can try testing this evening.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/28260?ContentTypeID=1Tue, 30 Jun 2015 06:34:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:437d1511-59f5-4537-b99b-061ad9e59674&#216;yvind Karlsen<p>Hi Lucas,</p> <p>You should find that this issue is addressed by the answer to <a href="https://devzone.nordicsemi.com/question/39809/sometimes-pwm-signal-is-reversed/?answer=43078#post-id-43078">this question</a>.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/28259?ContentTypeID=1Mon, 29 Jun 2015 18:56:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:27a36977-7fd9-43a6-8285-765b68e7a51dLucas<p>I read the post. Seems simular to what I am seeing. I wrote my own pwm driver before nordic released theirs. It would seem that this issue has nothing to do with software.</p> <p>Can nordic confirm that the chip is in fact loosing hardware PPI events?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/28258?ContentTypeID=1Mon, 29 Jun 2015 18:12:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:be46efa7-4f61-423d-88c3-e17c4f9fa35aJohn<p>I believe this is a known issue on the nRF51 chips.
