https://devzone.nordicsemi.com/f/nordic-q-a/37558/sampling-data-with-4-adc-channels-on-nrf52-bl654-moduleHello, I&#39;m using BL654 module (nrf52840 inside); SDK15; softdevice s140; IAR. In my projects I&#39;m using peripherals: I2C(TWI), SPI. Project based on ble_app_uart example (most of sdk_config.h are default, exept TWI/SPI instances and timer3) My goalen-USTelligent Community 13Tue, 21 Aug 2018 07:43:47 GMThttps://devzone.nordicsemi.com/thread/145041?ContentTypeID=1Tue, 21 Aug 2018 07:43:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:733e0c34-38c3-4bf4-836c-e1a160dca196H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>I setup your configuration in the peripheral/saadc example, and tried to replicate the issue, but unfortunately; I was not able to do so.</p> <p>I connected AIN0 and AIN4 to VDD, AIN5 and AIN7 to GND, and the output is always consistent (+/- a bit of jitter):</p> <p><pre class="ui-code" data-mode="text">&lt;info&gt; app: ADC event number: 118 &lt;info&gt; app: channel: 0 value: 854 &lt;info&gt; app: channel: 5 value: -2 &lt;info&gt; app: channel: 4 value: 840 &lt;info&gt; app: channel: 7 value: -2</pre></p> <p>&nbsp;</p> <p>Do you see this issue often?
