SPI Configuration with CMSIS tool

[LukeL]

Hello,

I am developing a project based on combining two example projects;

\nRF5_SDK_15.2.0_9412b96\examples\peripheral\spi 

and 

\nRF5_SDK_15.2.0_9412b96\examples\ble_peripheral\ble_app_uart

My question is regarding the configuration of sdk_config.h with the CMSIS tool. When I try to configure the ble_app_uart project to include the SPI driver (and subsequent pin configs), I cannot find the options, and the CMSIS tool seem to present me with different options.

I know I can manually correct this in sdk_config.h, but I'm not a fan of tinkering with auto-gen files.

Any help is greatly appreciated.

thanks

Hi.

The reason you can't find the options is because CMSIS Configurator "reads" the text of the sdk_config.h for the project you have open, and presents a GUI version based on the text.

For example, in the nRF5_SDK_15.2.0_9412b96\examples\peripheral\spi example's sdk_config.h file:

// <h> Application 

//==========================================================
// <h> SPI_CONFIGURATION - Spi configuration

//==========================================================
// <o> SPI_SCK_PIN  - Pin number

// <o> SPI_MISO_PIN  - Pin number
 
// <o> SPI_MOSI_PIN  - Pin number

// <o> SPI_SS_PIN  - Pin number

// <o> SPI_IRQ_PRIORITY  - Interrupt priority
 
// </h> 
//==========================================================

// </h> 
//==========================================================

// <h> nRF_Drivers 

//==========================================================
// <e> GPIOTE_ENABLED - nrf_drv_gpiote - GPIOTE peripheral driver - legacy layer
//==========================================================

You can see that <h> in represents a folder, and <o> represents an option in the sdk_config.h file

So in order to find more options you have to either:

1) Add the options you want to sdk_config.h

2) Start with a sdk_config.h file which has all the options found in one of the subfolders of nRF5_SDK_15.2.0_9412b96\config.

Best regards,

Andreas
