Confusing how to integrate SPI master and slave drivers/HAL in my C code

RE: Confusing how to integrate SPI master and slave drivers/HAL in my C code

Ok so I fixed the issue. Issue occurs if I associate same device id with both master and slave instances:

#define SPI_DEV_ID_0 0


nrfx_spim_t const hSpiMasterDev0 = NRFX_SPIM_INSTANCE(SPI_DEV_ID_0);
nrfx_spis_t const hSpiSlaveDev0 = NRFX_SPIS_INSTANCE(SPI_DEV_ID_0);

sdk_config.h:

// <e> NRFX_SPIM_ENABLED - nrfx_spim - SPIM peripheral driver
//==========================================================
#ifndef NRFX_SPIM_ENABLED
#define NRFX_SPIM_ENABLED 1
#endif
// <q> NRFX_SPIM0_ENABLED  - Enable SPIM0 instance
 

#ifndef NRFX_SPIM0_ENABLED
#define NRFX_SPIM0_ENABLED 1
#endif

// <q> NRFX_SPIM1_ENABLED  - Enable SPIM1 instance
 

#ifndef NRFX_SPIM1_ENABLED
#define NRFX_SPIM1_ENABLED 0
#endif


// <e> NRFX_SPIS_ENABLED - nrfx_spis - SPIS peripheral driver
//==========================================================
#ifndef NRFX_SPIS_ENABLED
#define NRFX_SPIS_ENABLED 1
#endif
// <q> NRFX_SPIS0_ENABLED - Enable SPIS0 instance

#ifndef NRFX_SPIS0_ENABLED
#define NRFX_SPIS0_ENABLED 1
#endif

// <q> NRFX_SPIS1_ENABLED - Enable SPIS1 instance

#ifndef NRFX_SPIS1_ENABLED
#define NRFX_SPIS1_ENABLED 0
#endif

However, if I change the device id for master and slave instances then problem goes away and it compiles & links successfully:

#define SPI_DEV_ID_0 0
#define SPI_DEV_ID_1 1

nrfx_spim_t const hSpiMasterDev0 = NRFX_SPIM_INSTANCE(SPI_DEV_ID_0);
nrfx_spis_t const hSpiSlaveDev0 = NRFX_SPIS_INSTANCE(SPI_DEV_ID_1);

sdk_config.h:

// <e> NRFX_SPIM_ENABLED - nrfx_spim - SPIM peripheral driver
//==========================================================
#ifndef NRFX_SPIM_ENABLED
#define NRFX_SPIM_ENABLED 1
#endif

#define NRFX_SPIM0_ENABLED 1
#endif

#endif

#define NRFX_SPIS0_ENABLED 0
#endif

// <q> NRFX_SPIS1_ENABLED - Enable SPIS1 instance

#ifndef NRFX_SPIS1_ENABLED
#define NRFX_SPIS1_ENABLED 1
#endif

Thanks Nguyen Hoan Hoang I will have a look.

So what I did so far I am linking my project with only nrfx drivers and their headers, namely:

modules\nrfx\drivers\src\nrfx_spis.c
modules\nrfx\drivers\src\nrfx_spim.c

I changed my code to use only functions in the headers for above driver.

From my sdk_config.h, I also removed many SPI legacy macros which are irrelevant.

sdk_config.h:

// <e> NRFX_SPIM_ENABLED - nrfx_spim - SPIM peripheral driver
//==========================================================
#ifndef NRFX_SPIM_ENABLED
#define NRFX_SPIM_ENABLED 1
#endif
// <q> NRFX_SPIM0_ENABLED  - Enable SPIM0 instance
 

#ifndef NRFX_SPIM0_ENABLED
#define NRFX_SPIM0_ENABLED 1
#endif

// <e> NRFX_SPIS_ENABLED - nrfx_spis - SPIS peripheral driver
//==========================================================
#ifndef NRFX_SPIS_ENABLED
#define NRFX_SPIS_ENABLED 1
#endif
// <q> NRFX_SPIS0_ENABLED  - Enable SPIS0 instance
 

#ifndef NRFX_SPIS0_ENABLED
#define NRFX_SPIS0_ENABLED 1
#endif


/* COMMENTED OUT SPI macros for unused spi driver or legacy drivers

// <e> NRFX_SPI_ENABLED - nrfx_spi - SPI peripheral driver
//==========================================================
#ifndef NRFX_SPI_ENABLED
#define NRFX_SPI_ENABLED 0
#endif
// <q> NRFX_SPI0_ENABLED  - Enable SPI0 instance

#define NRFX_SPI0_ENABLED 0
#endif

#ifndef SPIS0_ENABLED
#define SPIS0_ENABLED 1
#endif

#define SPI0_ENABLED 1
#endif

However, astonishingly I am still getting the same error.

Error[Li006]: duplicate definitions for "SPIM0_SPIS0_TWIM0_TWIS0_SPI0_TWI0_IRQHandler"; in "D:\nRF\sdk\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\custom_project\pca10040\s132\iar\_build\nrfx_spim.o", and 
"D:\nRF\sdk\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\custom_projectbmn\pca10040\s132\iar\_build\nrfx_spis.o"

I saw another related post: "SPIM3 initialization issue" , however SPI rleated macros still remain confusing.

Not able to proceed forward.

Those drivers are very messy. Try this one instead. It's been used and tested with lots of devices, sensors, flash,...

I am getting following error on compilation and linking:
