thanks, I was looking for the nrf_drv_config.h file.

This was meant more as a general clarification for the user. You are correct that the BLE examples now contain paths to all modules, but this is not the case for all non-BLE examples (peripheral/nfc/proprietary_rf, etc.) in the current SDK (12.2.0).

Re: Item 3 I've found that the example Keil projects and also the gcc makefile normally contain include paths to virtually everything, even if its not needed in the specific example

In this case the ble_app_template (in SDK 12.1 and 12.2 ) already contains the paths to the SPIM and also TWI driver folders in the include paths

But the user has to add includes for those headers in any file which uses SPIM (or TWI), i.e this could be in main.c or any other source file which use SPIM or TWI

Hi,

There are four things you have to add/verify when adding modules to a Keil project:

Add the source files (.c) for the module to groups in Keil.
Include the header file (.h) in the source file where the module is used.
Add the path to the header file to the include paths in C/C++ project options.
Enable the module in SDK configuration header file. If you cannot find the settings for the desired module in the sdk_config.h file for your project, check in ble_app_template project sdk_config.h file, as this include all modules in the SDK.

Step 1-3 is described in more details in section Add required files and includes of the Application Timer Tutorial. All steps are shown in below image:

Best regards,

Jørgen

Your most likely cause of errors is that you have not enabled SPI and TWI in sdk_config.h

Unless you enable those modules in that file, the functions won't get compiled and you will get loads of errors.

I assume you are using an IDE like Keil, or IAR in which case it will handle adding the spi and twi c files to the build list if you added them to the project

If you are using gcc / makefile, you'd need to manually add those files to the makefile
