Hello,
I'm going to use nrf52-ble-image-transfer-demo-master for my application. But demo used other way with cpp code for configuring nrf52832 interfaces(spi, twi, gpio...) I hope to use ordinary library and function, but for example if I configure spi like below
sdk_config.h
// <e> SPI_ENABLED - nrf_drv_spi - SPI/SPIM peripheral driver
//==========================================================
#ifndef SPI_ENABLED
#define SPI_ENABLED 1
#endif
#if SPI_ENABLED

// <0=> 0 (highest)

// <4=> 4
// <5=> 5

// <7=> 7
#ifndef SPI_DEFAULT_CONFIG_IRQ_PRIORITY
#define SPI_DEFAULT_CONFIG_IRQ_PRIORITY 7
#endif
// <e> SPI0_ENABLED - Enable SPI0 instance

APP_ERROR_CHECK(nrf_drv_spi_init(&spi, &spi_config, spi_event_handler, NULL));
}
I get errors like

How can I use nrf52 interface through ordinary method? I'm using nrf52832 DK.
