https://devzone.nordicsemi.com/f/nordic-q-a/75638/nrf5340-about-i2s-debugging我正在使用NRF5340DK调试I2S功能。我完成了I2S的初始化，并打开了TASKS_START.我通过示波器看见MCK和LRCK都程序产生了理想的波形。但是SCK和SDOUT都没有波形产生。我还发现打开TASKS_START后，事件EVENT_TXPTRUPD、EVENTS_RXPTRUPD和EVENTS_FRAMESTART依次被触发一次，但是后面触发事件再也没有发生。 请问我应该如何解决这个问题。谢谢。 I am using NRF5340DK to debug I2S functionsen-USTelligent Community 13Sat, 29 May 2021 08:02:25 GMThttps://devzone.nordicsemi.com/thread/312492?ContentTypeID=1Sat, 29 May 2021 08:02:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37234749-4108-4040-a2d9-95efd3d9c1bamingjkl<p>Thank you very much for your patience. I tried the solution you provided. I2S works normally.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/312065?ContentTypeID=1Thu, 27 May 2021 11:42:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5e635a76-9490-4bc1-bb94-81c2387739f4Carl Richard<p>Hello!<br /><br />Thanks for reaching out. I see that you are using P0.19 and P0.21 for the SCK and LRCK signals. On the DK these pins are reserved for the UART connection with the interface MCU as described in the <a href="https://infocenter.nordicsemi.com/topic/ug_nrf5340_dk/UG/dk/connector_if.html">DK documentation</a>. Could you please try using different pins, like P0.11 and P0.12?&nbsp;<br /><br />If this doesn&#39;t help please report back and I&#39;ll take a closer look.<br /><br />Best regards,<br />Carl Richard</p><div style="clear:both;"></div>
