https://devzone.nordicsemi.com/f/nordic-q-a/17187/capacitive-touch-with-nfr52I&#39;m currently making a device which use nRF52832 and that will integrate Capacitive touch feature. However, I&#39;m actually a bit lost with this post: devzone.nordicsemi.com/.../ And this note : Due to erratum 84 (COMP: ISOURCE not functional), capacitiveen-USTelligent Community 13Fri, 21 Oct 2016 08:36:13 GMThttps://devzone.nordicsemi.com/thread/66010?ContentTypeID=1Fri, 21 Oct 2016 08:36:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:29d1ae46-7aa2-4ed5-a036-a90a39796d89Einar Thorsrud<ol> <li>Your understanding is correct. The programmable current source (ISOURCE) in the COMP peripheral is so unstable over temperature that it should not be used (<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.Rev1.errata/anomaly_832_84.html?cp=2_2_1_0_1_22">erratum 84</a>).</li> <li>The <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.0.0/hardware_driver_csense.html?cp=4_0_0_2_1">Capacitive Sensor driver</a> from the SDK support RC charge timing using the ADC with a <em>common</em> pin for charging the sensor pads through a resistor.
