RE: SPI with Audio Example

Hi,

I had to change name from .config to config.txt. I wonder if there is a simple tutorial how to add spi, i2c and so on to the nrf connect sdk application? It really shouldn't be that complex. With nrf5 sdk it would take me 2 minutes.

Thanks,
Michal

Hi,

Could I see the file at <build>/zephyr/.config ?

To add a devicetree overlay, add a file with the same name as your board and file ending .overlay to your project folder.
example: nrf5340_audio_dk_nrf5340_cpuapp.overlay

Hi,

I am getting compile errors, that's why I am wondering how to properly include SPI. Here is a full error log:

I can't set up Nrf Connect SDK support in Visual Studio for some reasons, how do I manually add devicetree overlay ?

Best regards,

Hello Michal,

Thank you for your patience with this.

[quote user=""]I have been looking for some examples of SPI slave in general, but I am a bit confuzed which API should be used: nrfx_spi (nordic specifc) or zephyr generic API? I see i2s is using nordic specific API. So far I have added [/quote]

You can use the generic Zephyr API, which will route to the NRFX API behind the scenes, since the SPI peripheral is nrfx compatible (as described in its devicetree)

[quote user=""]to my KConfig.defaults, but I am still getting some errors, when I try to set up SPIS communication.[/quote]

Could you elaborate on which errors you are getting? Is this compile time errors, or runtime?

[quote user=""]What are proper steps to include SPI in nrf5340_audio application ?[/quote]

The general approach is to add it to your device tree overlay file, and then enable and configure the necessary kconfig options (such as in your prj.conf file).
You can use the 'Devicetree' action in Visual Studio code to more easily make the necessary changes to your existing application's device tree.

Best regards,
Karl
