multiple definition of `SPI1_TWI1_IRQHandler'

[ashare]

Hi :

In my application, i need to use 2 spi master (SPI0,SPI1) and spi slave the same time, but when i compiled drivers_nrf/hal/nrf_spi.h and drivers_nrf/hal/nrf_spis.h, it showed "multiple definition of `SPI1_TWI1_IRQHandler'" error.

then I found in sdk_config.h, SPIS1_ENABLED default set 1, I changed it to 0 and SPIS2_ENABLED to 1, it showed "'NRF_SPIS2' undeclared" , how can i set sdk_config.h?

we use 51822 pca10028 board with sdk12.2 and gcc 4.9.3

Hi,

The SPIS instance you have enabled in sdk_config.h need to correspond to the one you use in main.c

If you have set SPIS1_ENABLED to 1, you should use this instance in main.c:

#define SPIS_INSTANCE 1 /**< SPIS instance index. */
static const nrf_drv_spis_t spis = NRF_DRV_SPIS_INSTANCE(SPIS_INSTANCE);/**< SPIS instance. */

I did what you said, but it didn't work. It logged : ... In function 'SPIS2_IRQ_HANDLER':nrf_drv_spis.c:85:26: error: 'NRF_SPIS2' undeclared

On the nRF51 there is only 1 SPI slave, SPIS1, so you need to use SPIS 1 instead of 2.

On the nRF51 you have:

SPI0 Master

SPI1 Master

SPIS1 Slave

At first, I set it up like this: SPI0 MASTER,SPI1 MASTER and SPIS1 SLAVE, but there was an error: hal/nrf_spis.h:374: multiple definition of `SPI1_TWI1_IRQHandler'

and now I set SPI0 MASTER, SPI2 MASTER and SPIS1 SLAVE, there was an error : nrf_drv_spi.c:650:25: error: 'NRF_SPI2' undeclared. it seems that 51822 only has 2 spi master and 1 spi salve, and spi1 master can not use with spis1 salve the same time, doesn't it?
