https://devzone.nordicsemi.com/f/nordic-q-a/2143/die-temperature-51822hi Ole Morten: thank you for your great support. i have tested nrf6310\temperature_example. at 30(Celsius) I checked the data. NRF_TEMP=0x000002AF; TEMP=0xFFFFFFAC; what&#39;s the NRF_TEMP data type? 10bit 2&#39;s complement or 32bit 2&#39;s complementen-USTelligent Community 13Tue, 08 Apr 2014 13:28:04 GMThttps://devzone.nordicsemi.com/thread/9114?ContentTypeID=1Tue, 08 Apr 2014 13:28:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bfd00b5b-7b6e-4c52-bff3-302f5f3bb9faHung Bui<p>Hi Kevin,</p> <p>It&#39;s the 32bit 2&#39;s complement with the actual max (positive and negative) value of 10 bit. So for example if the temperature value (0.25oC unit) is -2 you will have: 0xFFFFFFFE. And the maximum negative value it can get is 0xFFFFFC00.</p> <p>Note that, on the first version of the chip, a bug fix is needed, please refer to PAN document, issue #28 (already fixed in the SDK) Secondly, even on new chip version (XLR2), manual offset calibration, in some cases, are still needed.</p><div style="clear:both;"></div>
