Thank you it worked, I still have other errors I'm going to check why.

You also need to enable the TWI0 or TWI1 instance

#ifndef TWI0_ENABLED
#define TWI0_ENABLED 1
#endif

You might want to check the sdk_config.h file in the twi example from nordic.

I have nrf_drv_twi.c in my project but the errors still there.

What do I need to add to the sdk_config.h ?

#ifndef NRF_MODULE_ENABLED

#define NRF_MODULE_ENABLED 1

#endif

is correct ?

Hello,

Did you add nrf_drv_twi.c in your Keil project?

This error means the linker only has the declarations of the functions but he doesn't find the definitions.

Also make sure you have enabled TWI Module in your sdk_config.h, otherwise you won't compile the twi definitions in nrf_drv_twi due to the #if NRF_MODULE_ENABLED(TWI) guard.
