https://devzone.nordicsemi.com/f/nordic-q-a/112214/nrf5340-audio-dk---i2s---send-audio-in-zephyrHello, I am using the nRF5340 Audio DK with Zephyr and want to use I2S to send audio to an I2S device. So far I have had little success with the microcontroller halting in the arch_system_halt() function. So far I have managed to get a similar codeen-USTelligent Community 13Wed, 19 Jun 2024 13:44:28 GMThttps://devzone.nordicsemi.com/thread/489550?ContentTypeID=1Wed, 19 Jun 2024 13:44:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e5d689ae-6827-4c9c-8fab-1fd843491c12Elfving<p>Hello,</p> <p>So when you specify that you want to do this with Zephyr, do you mean NCS, or do you want to just use Zephyr? Have you considered using the NCS Audio App? Are you necessarily doing <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/doc/firmware_architecture.html">LE Audio</a>?</p> [quote user=""]It has generally been quite difficult to search for good guides regarding I2S and the nrf series. Especially examples/guides regarding development with Arduino/platformio that actually work.[/quote] <p>Yeah, I guess everything related to Audio is a bit more on the complex side, which means that it is best supported on NCS&amp;Zephyr. It would be difficult to handle this complexity without and RTOS. <a href="https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/applications/nrf5340_audio/index.html#nrf5340-audio-applications">I do like this documentation we have on our LE Audio Application</a>, though having support for Arduino is not something we&#39;ve prioritized.</p> <p>Regards,</p> <p>Elfving</p><div style="clear:both;"></div>
