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.

Hi,

You can find SPI master and slave examples in this post. I have tested the master example on nRF5340, and it needed a small change to build, see this post. I assume a similar change would be needed for the slave example.

Best regards,
Jørgen

You get that error because you did not add the changes mentioned in the second thread I linked.

Hi,

SRINI said:

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

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

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?

SRINI said:

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

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

Best regards,

Hi,

Thanks for the response. 

My problem is resolved. I am confused in pin connection. After change the pin connections it's working fine.

Hi! I'm trying to build the example (SPI Master) but I was not able to compile without errors.

My environment is SDK 2.2.0, the board choosed is the Nordic 5340dk (I have an Ublox NORA EVK 106-B that is pretty similar & I have also the device tree). The output is:

The same output if I try with the Ublox Board.

I didn't understand the modifications that I need to do in the project to make it buildable.

The target is to build a working example for the Ublox EVK & SPI4 in order to test the SPIM API.

Could anyone support me?

Many Thanks & Best Regards

Other info:

I noticed that several inclusion files like as zephyr.h or nrf.h, for example, introduced fatal errrors.

I can include <nrfx.h>, <nrfx_spim.h> and <nrfx_gpiote.h> instead of.

Seems that the 2.2.0 SDK does not permit that.

------------------------------------------------------------------------

Update 2023/07/13 - 12:06 AM:

- I try to port one piece at time into my project in wich I have a DT che define the SPI4.

- The inclusions are: #include <nrfx.h>, #include <nrfx_spim.h>, #include <nrfx_gpiote.h>

- I tested a declaration of a spi's type
  static nrfx_spim_config_t spim_config = NRFX_SPIM_DEFAULT_CONFIG(APP_SPIM_SCK_PIN, APP_SPIM_MOSI_PIN, APP_SPIM_MISO_PIN, APP_SPIM_CS_PIN); . And it coimpile with success.

- If I insert the ISR:  

static void manual_isr_setup(){

#ifdef NRF9160_XXAA

    IRQ_DIRECT_CONNECT(UARTE3_SPIM3_SPIS3_TWIM3_TWIS3_IRQn, 0,

               nrfx_spim_3_irq_handler, 0);

    irq_enable(UARTE3_SPIM3_SPIS3_TWIM3_TWIS3_IRQn);

#else  

    IRQ_DIRECT_CONNECT(SPIM3_SPIS3_TWIM3_TWIS3_SPI3_TWI3_IRQn, 0,

               nrfx_spim_3_irq_handler, 0);

    irq_enable(SPIM3_SPIS3_TWIM3_TWIS3_SPI3_TWI3_IRQn);

#endif

}

The building failed because the SPIM3_SPIS3_TWIM3_TWIS3_SPI3_TWI3_IRQn is not declarated.

Thanks Again
