Are they initialized as UART pins? For some other peripherals? Are they input pins or output pins? Or are the pins not used at all (uninitialized)?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170543?ContentTypeID=1Tue, 12 Feb 2019 09:30:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:85b88763-735e-4499-b4c7-c9b6ff4dc7d1Edvin<p>Does it occur all the time, or only when you use certain peripherals?</p> <p>Can you describe what peripherals you use in your application? Can you test the same pins on e.g. the examples\peripheral\blinky example?</p> <p>What HW do you use? Is it a DK or a custom PCB?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170457?ContentTypeID=1Mon, 11 Feb 2019 18:13:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:26debedb-ce0b-4e57-bcd7-6f9623b5a36bHarrySpencer<p>it is 100mV p-p</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/170404?ContentTypeID=1Mon, 11 Feb 2019 14:28:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:96fd8666-30d4-4d01-b09a-2de9556a17b4Edvin<p>Hello,</p> <p>The grid that you use is 5mV, is that correct?</p> <p>This could be noise from the radio or the NFC (if you use this), or nearby pins. Does these 5mV noise disturb your application?</p> <p></p> <p>Best regards,<br />Edvin</p><div style="clear:both;"></div>
