nRF5340 SPI example code

[SRINI]

Hi,

could you provide me an example codes for SPI (serial peripheral communication), SPIM(serial peripheral communication master) and SPIS(serial peripheral communication slave) for nRF5340 SoC.

Thanks & Regards,

Srinivas.

Do you have any example codes with built-in SPI driver in Zephyr ? .

please let me know how can we do SPI configuration and pin settings.

See this post.

[SRINI]

we have two ports for nRF5340 which port 0 and port 1.

In SPI master code , where port is defined in the code.

[SRINI]

NRFX_PRS_ENABLED macro is disabled in nrfx_spim.c file.
I am getting below error, if I enable this macro using nrfx_config_nrf5340_application.h file.

undefined reference to `nrfx_prs_acquire'

May I know why it is disabled in nrf connect SDK and I didn't face this issue when Iam work with nRF5 SDK for nrf52832

Do you mean GPIO port 0 and port 1?

 Which SPI master code are you using now? The nrfx_spim example, or the one using the native Zephyr SPI API?

You can enable PRS in NCS by adding the Kconfig CONFIG_NRFX_PRS=y to your prj.conf file (or an overlay file).
