RE: Fails to use NRFX modules

In SDK 15 the pheriperal drivers are using NRFX, however it may seem like the legacy driver are still used since the legacy API is used. E.g. in the main file of the GPIOTE example, the function nrf_drv_gpiote_init() is used, however this is remapped to the new NRX function nrfx_gpiote_init().

In the sdk_config.h file, both of the legacy definitions and the NRFX definitions are apparent. The way I would go about this (the easy way), is to ignore the NRFX definitions and use the old legacy definitions. In the same way the legacy funtions are remapped to the NRFX functions, the legacy definitions are remapped to the NRFX definitions. For example if you set GPIOTE_ENABLED to 1 and NRFX_GPIOTE_ENABLED to 0. You will end up with NRFX_GPIOTE_ENABLED being equal to 1, due to this line in apply_old_config.h:

#if defined(GPIOTE_ENABLED)

#undef NRFX_GPIOTE_ENABLED
#define NRFX_GPIOTE_ENABLED  GPIOTE_ENABLED

Does this make sense, or are you even more confused? Please ask if so.

Best regards,

Simon

Drivers from this project is much better written. You can configure everything at runtime. Unlike the SDK, It doesn't have thousands of conditional compilation defines. It also supports both C & C++ code optimized and more performance than the SDK.
