The nRF51 SDK (version 9) documentation tells to activate SPI using the SPI_MASTER_0_ENABLE and SPI_MASTER_1_ENABLE macros. Where should these definitions be made? Other components seem to use nrf_drv_config.h for their configuration but spi_master does not include this file. Why is SPI treated differently?
Update: In the meantime, SDK version 10 was released. There, the issue has been resolved and the new SPI driver offers a very easy way of configuration and usage. Further, both synchronous (blocking) and asynchronous (callback event) SPI operations are supported an SS handling of the driver can be disabled.
