I2S BCLK and double signal issuehttps://devzone.nordicsemi.com/f/nordic-q-a/48363/i2s-bclk-and-double-signal-issueI am trying the demo from github ( https://github.com/andenore/NordicSnippets/blob/master/examples/i2s_master/main.c ) with nrf52 demo board and when checking the signal on BCLK I see that it is doubled. Like Any ideas why this is happening?en-USTelligent Community 13Tue, 11 Jun 2019 08:23:52 GMTRE: I2S BCLK and double signal issuehttps://devzone.nordicsemi.com/thread/191954?ContentTypeID=1Tue, 11 Jun 2019 08:23:52 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e3cb67f9-cbc4-41b6-b801-d483a1e6031abojerko<p>Yes. It looks like it was really a GND issue. Not sure what I did, but managed to get the proper signal to the screen.</p> <p>I&#39;m still struggling with the i2s one sine demo from the examples, since I don&#39;t get a sine signal on the scope.</p><div style="clear:both;"></div>RE: I2S BCLK and double signal issuehttps://devzone.nordicsemi.com/thread/191934?ContentTypeID=1Tue, 11 Jun 2019 07:53:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:61a9710e-50ad-4ae5-8175-d2091cc33a29H&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>This type of signal is normally due to bad grounding. Could you check your connection and see if it improves?</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
