nRF24L01+ XC1 driving by MCU PWMhttps://devzone.nordicsemi.com/f/nordic-q-a/7712/nrf24l01-xc1-driving-by-mcu-pwmHello. I&#39;m using 24 MHz crystal to feed my MCU and not able to change it to 16 MHz to share with nrf24. Now I&#39;m driving nrf24 XC1 with PWM signal 16 MHz and it works but not stable. Can i get any advice how to improve stability. http://clip2net.com/sen-USTelligent Community 13Mon, 06 Jul 2015 13:47:34 GMTRE: nRF24L01+ XC1 driving by MCU PWMhttps://devzone.nordicsemi.com/thread/27476?ContentTypeID=1Mon, 06 Jul 2015 13:47:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5cf08255-db48-4dfc-ba6f-657ae1cf0a05H&#229;kon Alseth<p>Hi,</p> <p>The 16M clock source needed by the nRF24L01+ has to be within the parameters given in chapter 5.5 in the nRF24L01+ datasheet.</p> <p>The frequency shall be 16.000 MHz, with a tolerance of max. +/- 60 ppm.</p> <p>The signal shall be fed into pin &quot;XC1&quot; when driven from an external source.</p> <p>Have you made sure that all of the above criterias has been satisfied?</p> <p>Cheers, Håkon</p><div style="clear:both;"></div>
