https://devzone.nordicsemi.com/f/nordic-q-a/64756/nrfx-temperature-driver-nrf52840-sdk-17-0-0Hi, the nrfx driver for the internal temperature sensor has been introduced with SDK 16,0.0, Since I started developing with SDK 15.02, I have used so far the old HAL driver, which works fine. Now I tried to switch to the new NRFX driver (using nonen-USTelligent Community 13Thu, 13 Aug 2020 07:33:53 GMThttps://devzone.nordicsemi.com/thread/264367?ContentTypeID=1Thu, 13 Aug 2020 07:33:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:06095896-298b-40a9-9819-7ba24814fcfedzabel<p>Thank you. I had the false expectation that the NRFX driver cares for this and thought it would be &quot;cleaner&quot; to use the NRFX driver, but if I look into the source, I can see it does not. Than I will stick with my old code which uses sd_temp_get() if SOFTDEVICE_PRESENT is defined.</p> <p></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/264360?ContentTypeID=1Thu, 13 Aug 2020 07:01:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:67ebec65-bc33-406e-9288-0a3506e220b0Einar Thorsrud<p>I second that.&nbsp;You must use the SoftDevice API to use the TEMP peripheral, as that is protected (and used) by the SoftDevice. Therefore writing to TEMP registers directly is not allowed and&nbsp;will trigger an invalid memory access fault.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/264265?ContentTypeID=1Wed, 12 Aug 2020 12:31:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fa7199f1-54e2-4d05-bf2b-ef9b79121649Patrick<p>Have you tried using the soft device specific functions for getting temp? If I am not mistaken, the info center page for the temp library provides more detail on how to get the core temp when using the SD.&nbsp;</p><div style="clear:both;"></div>
