nRF52840 I2S Zephyr / VS Code Example

Question

Hi, 
 I'm trying to find an example of using the I2S audio interface with the Zephyr RTOS on the nRF52840dk_nRF52840 development board or on an nRF52840 device in general. Is there an example somewhere? 
 If I2S is not supported through the Zephyr RTOS, is there a way to access the legacy I2S drivers for the nRF52840 from within the nRF SDK5 / Zephyr / VS Code development environment while still having access to the rest of the Zephyr OS for other uses? 
 Thanks, 
 Glen

Is there an example somewhere? 
 Check out these samples (use NCS v1.8.0): 
 https://github.com/nrfconnect/sdk-zephyr/tree/v2.7.0-ncs1/samples/drivers/i2s 
 As well as the i2s tests: 
 https://github.com/nrfconnect/sdk-zephyr/tree/v2.7.0-ncs1/tests/drivers/i2s 
 This bare metal sample is also worth taking a look at if you want to understand the i2s from the bottom up: 
 https://github.com/andenore/NordicSnippets/blob/master/examples/i2s_master/main.c

 Support for the Nordic i2s using the Zephyr api was just added: https://github.com/zephyrproject-rtos/zephyr/pull/34251/commits (NCS v1.8.0), so there is no need to use the NRFX drivers.
