nRF 52832: The ADC error varies from chip to chip and calibration doesn&#39;t solve it fullyhttps://devzone.nordicsemi.com/f/nordic-q-a/40403/nrf-52832-the-adc-error-varies-from-chip-to-chip-and-calibration-doesn-t-solve-it-fullyHi, Everyone, We are developping BLE project on nRF52832 chip. We need to measurethe battery voltage to determine the remmended charge in it. For this purpose we activated the ADC that measures VCC voltage. We configured it to the next parametersen-USTelligent Community 13Mon, 19 Nov 2018 15:31:52 GMTRE: nRF 52832: The ADC error varies from chip to chip and calibration doesn't solve it fullyhttps://devzone.nordicsemi.com/thread/158031?ContentTypeID=1Mon, 19 Nov 2018 15:31:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:765c5555-b10d-4901-be11-a770a5ad0fc8bjorn-spockeli<p>Hi Boris,&nbsp;</p> <p>which SDK version are you using?</p> <p>Can you post the code snippet where you initialize the SAADC and the event handler where you calculate the battery voltage?</p> <p>Have you generated a&nbsp;lookup table comparing OCV with SoC or obtained it from the battery manufacturer?&#39;</p> <p>Best regards</p> <p>Bjørn&nbsp;</p><div style="clear:both;"></div>
