Need a support to do spi interfacing in segger embedded studio using nRF51822 module

[PavanSgowda]

Dear Sir/Madam,

I'am new to segger embedded studio.I would like to do SPI interfacing of an IC using nRF51822 with segger embedded studio.

Please guide me how to add the necessary driver files into my project.

Hi,

If you do not already have the SES project for nRF51 up and running, there is a tutorial on how to convert a Keil project available here.

Regarding usage of SES with our SDK, please have a look the this video tutorial playlist on YouTube.

Best regards,
Jørgen

Hi Holmefjord,

Thank you for your support.

But What I need exactly is

Steps that has to be followed to create a new project in Segger Embedded studio to do spi interfacing using nrf51822 mcu.

What are the drivers I'am supposed to add into  the project and Where should I get them.

Please help me out since I'am running out of time in completing this simple task.

Regards,

Hi,

There is a SPI Master Example in the SDK that you can reference. The SPI master driver is found in "nRF5_SDK_12.3.0_d7731ad\components\drivers_nrf\spi_master", use the nrf_drv_spi.c/h version.

Best regards,
Jørgen

Hi,

I found the spi related drivers in the path suggested by you,and created a new folder(inside the project in SES) and added the required files(spi master files) in that folder,But getting some errors.

What is the procedure we need to follow to add those required files into my project.

You can add the driver to the project without copying it. The following should be sufficient to use the driver:

• Add the source file (nrf_drv_spi.c) to your project.
• Add the path to the header file (nrf_drv_spi.h) to your project settings.
• Add the configuration for the SPI master driver to your sdk_config.h file, or enable it if the config is already present.

It would be easier to help you if you could post the actual error codes that you get.
