Hi guys! I want to add SPI to my BLE project to read some data from my gyro. Adding other headers was no problem, but when I want to add some code from the SPI-Example I got some errors I can't fix.
I've added the headers to a SPI-Header
#include "nrf_drv_spi.h"
#include "nrf_gpio.h"
#include "boards.h"
as well as to the project include path
..\..\..\SDK\components\drivers_nrf\spi_master
and added the nrf_drv_spi.c.
But unfortunately the Keil IDE says "undeclared identifier"
But the nrf_drv_config.h is added to my project as well, where the definition of SPI0_USE_EASY_DMA is declared. Adding the header directly to the spi.h doesn't work either. Compiler also says "Browse information for nrf_drv_spi.c is not available", no matter how much I clean and rebuild.
Build-Log looks like this
compiling spi.c...

Did I miss something? How do I add SPI to my project properly? BTW, is there an example for using SPI without NRF-Libs?
