Thanks again, Jørgen. I replaced my nrf_drv_twi files and I got rid of this error.

You can find the default sdk_config.h settings for TWI in the TWI sensor example. You should only edit the sdk_config.h file, and not put the defines in main.c or nrf_drv_twi.c/h.

Thanks, and sorry I am still new with this. I added both #define TWI_ENABLED 1 and #define TWI0_ENABLED 1 to my main.c file. Also, I modified "sdk_config.h" to define both values as well. However, I am still receiving the error. Not sure what is going wrong.

EDIT: I should probably note that I also have enabled TWI0_USE_EASY_DMA. Looking at "nrf_drv_twi.h",

#if ((TWI0_ENABLED == 1 && TWI0_USE_EASY_DMA == 1) ||
(TWI1_ENABLED == 1 && TWI1_USE_EASY_DMA == 1)) #define TWIM_IN_USE #endif

Having both enabled should define TWIM_IN_USE and fix this error, but I'm not sure what's going wrong.

Hi,

As I answered in your last case, nrf_drv_config.h is no longer used in SDK 12.x.0. You should enable TWI by setting TWI_ENABLED and TWI0_ENABLED in, sdk_config.h as described here.

Best regards,

Jørgen
