Where should the SPI master enable definition be set? (nRF51 SDK v9)https://devzone.nordicsemi.com/f/nordic-q-a/9890/where-should-the-spi-master-enable-definition-be-set-nrf51-sdk-v9The 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 doesen-USTelligent Community 13Mon, 09 Nov 2015 17:09:50 GMTRE: Where should the SPI master enable definition be set?

All drivers that have nrf_drv_* prefix have been included in the nrf_drv_config.h setup. I suspect the SPI will eventually be put into the same platform. Meanwhile, it is still spi_master, but until it becomes nrf_drv_spi_master, I guess it will be enabled with a preprocessor symbol.</p><div style="clear:both;"></div>RE: Where should the SPI master enable definition be set?

In fact, I now that I can set preprocessor symbols (I&#39;m using GCC with makefile, though). I was just wondering why the SPI driver is treated differently (or if there is a differnet place where all drivers should be configured). For a straightforward software design, it would be nice to have all hardware configuration in the same place. Sorry for not making this clear in my initial question.</p><div style="clear:both;"></div>RE: Where should the SPI master enable definition be set?

Concerning the SPI master driver, I also hope that we will get a method for switching the SS signal during operation, something like described in this thread: <a href="https://devzone.nordicsemi.com/question/29156/spi-with-multiple-chip-selects/.">devzone.nordicsemi.com/.../.</a></p><div style="clear:both;"></div>RE: Where should the SPI master enable definition be set?
