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 ?
The SPI driver code is independent of the softdevice. You can just take the code and use it without a softdevice and it will work fine. All the Nordic drivers are standalone and work with or without softdevices.
If there are any places which use any sd_* functions at all, eg for configuring interrupts etc, there are a few files in the SDK with 'nosd' in their names which just provide trivial c implementations of those functions for simple source compatibility .. or you can just replace them with direct NVIC calls.
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
