https://devzone.nordicsemi.com/f/nordic-q-a/77334/calibration-saadc-on-a-zigbee-divice-nrf52840Hi! There is an end device that measures the temperature. If I calibrate the ADC during initialization or immediately after startup, the program hangs. If I start the calibration after some time (I do it every 20 measurements, but I start with 19 anden-USTelligent Community 13Thu, 15 Jul 2021 11:20:48 GMThttps://devzone.nordicsemi.com/thread/320223?ContentTypeID=1Thu, 15 Jul 2021 11:20:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e8c32ea7-6985-495f-9fa8-649055df1e76Litvinus<p><span>Hi,&nbsp;</span></p> <p>My mistake, I didn&#39;t read the manual, I just used the code from the example. To stop the SAADC before calibration, the priority of the interrupt from which the stop is called must be lower than the priority of the SAADC.</p> <p><span>Thanks!</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/319591?ContentTypeID=1Mon, 12 Jul 2021 12:19:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:790ac282-0825-4617-8676-c9a6396d057bMarte Myrvold<p>Hi,</p> <p>Does it fail during initialization or after startup of the Zigbee stack, or the ADC? It is possible that the timer is blocking the Zigbee stack, causing the program to hang. When do you calibrate it?</p> <p>Best regards,</p> <p>Marte</p><div style="clear:both;"></div>
