I am trying to develop a simple SPI master for a custom nRF52832 uC, but I can't find anny sort of sample codes that don't use Soft devices for this task. I need the code to be simple, so no need for SD based codes. Is it possible or is the nordic SPI driver only usable through SD ?
In SDK 11 there are two examples, SPIS and SPI, located in "SDK_11_folder\examples\peripheral". These examples show how to use SPI slave and master using the SPI(S) drivers without using the SD. It is as RK says though, it doesn't really matter if you use the SD or not other than that things might be a little clearer without thousands of lines of BLE stuff in the way.
I am unable to create a project from scratch with the spi drivers and the necessary files. I tried to create a new project and added the nrf_drv_spi driver and all the associated driver and config files to the project run-time environment, but I still got those errors for just compiling
