Hello,
I'm evaluating the nRF5340 for a fairly basic bluetooth le audio transmitter device.
I'm using a standard nRF5430 development kit due to price/availability. I have a breakout for a Cirrus CS5343 A/D converter with i2s.
I want to test basic functionality with some of the nRF5340 Audio example, specifically I want to cut out the hardware codec stage and transmit audio directly from the i2s input.
I'm fairly new to this build system so the multiple default pinctrl configurations plus the Kconfig configurations are confusing me.
In prj.conf, I have added:
Additionally I have changed configurations in menuconfig, mainly configuring i2s as the audio source.
One thing that's tripping me up is understanding pinctrl and how I can cleanly create a "new" board, essentially the standard dk, with some of the audio_dk pin configurations for i2s.
Is what I'm describing doable in the context of the provided audio project? Or have I gone down a wrong path?
