#35: #error directive: "Wrong configuration." Enabling TWI

[Levi]

Hello,

I received the above error using NRF5 SDK 12.2. I have modified "nrf_drv_config.h" so that it reads #define TWI0_ENABLED 1. Also, I put #include "nrf_drv_config.h" at the top of all my files which use "nrf_drv_twi" where the error occurs.

I am not sure what to do now as the error still occurs.

Thank you,

Levi

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

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.
