porting I2S to nrf52 DK

I'm trying to port I2S to nrf52 DK board, but even though I include nrf_drv_i2s.h where nrf_drv_i2s_init, nrf_drv_i2s_start and nrf_drv_i2s_stop are I always get undefined reference error when linking is in the process:

/Users/bostjan/peskovnik/mauu/i2s_nordic_example/./main.cpp:190: undefined reference to `nrf_drv_i2s_init' /Users/bostjan/peskovnik/mauu/i2s_nordic_example/./main.cpp:199: undefined reference to `nrf_drv_i2s_start' /Users/bostjan/peskovnik/mauu/i2s_nordic_example/./main.cpp:205: undefined reference to `nrf_drv_i2s_stop'

Any ideas what I need to do?

Hi Boštjan,

We think the issue is that you likely haven't configured the Nordic SDK to include the I2S. Please try setting the "I2S_ENABLED" macro to "1" in the sdk_config.h file located here:

We think that will get the build working.

You're right. Tested it and it works out of the box.

Thanks.
