Multiple definition of SPIM0_SPIS0_TWIM0_TWIS0_SPI0_TWI0_IRQHandler

I am using all SPI instances and want to use a TWI instance as well. As soon as I add the nrfx_twi.c file I get 1> ...nrf\modules\nrfx\drivers\src/nrfx_twi.c:725: multiple definition of `SPIM0_SPIS0_TWIM0_TWIS0_SPI0_TWI0_IRQHandler'; Output/readoutmeter_demo_s140 Debug/Obj/nrfx_spim.o:nrf\modules\nrfx\drivers\src/nrfx_spim.c:676: first defined here

How can I do this, I do not require event handler for SPI or TWI, all communiction is supposed to by synchronous.

The framework is v16 and the device is a nRF52840.

Many of the serial interfaces share resources. This table shows the base address of the various pheripherals: https://infocenter.nordicsemi.com/topic/ps_nrf52840/memory.html#topic

The ones with the same base address share the same resource and can't be used simultaneously. So you have used all SPI instances, there are no free resources for TWI.

Thank you, that was a new (and strange) concept to me. Now it's somewhat understandable. This will require some soldering now ..
