Have you tried installing drivers in Keil using the Package installer? CMSIS Packs are no longer supported by our SDK.

Wow, that's super strange. The nrf_drv_config.h gets included from this folder "C:\Keil_v5 Microcontroller Development Kit\ARM\PACK\NordicSemiconductor\nRF_Drivers\4.0.0-2.alpha\twi_master" though this one is NOT in the list of include paths! But \components\drivers_nrf\twi_master is correctly in that list. How is that possible?

The nrf_drv_twi.h of SDK 12.2 looks like this:

#ifndef NRF_DRV_TWI_H__
#define NRF_DRV_TWI_H__

#include "nordic_common.h"
#include "sdk_config.h"

Make sure that you have the path to the correct header file in your project:

[SDK_12_2_0_ROOT]\components\drivers_nrf\twi_master

Yes I stumbled across this answer before but these lines are included in nrf_drv_twi.h (which i use):

#ifndef NRF_DRV_TWI_H__
#define NRF_DRV_TWI_H__

#include "nordic_common.h"
#include "nrf_drv_config.h"

I got the example right out of SDK 12.2

Hi,

See this answer (which you linked to yourself yesterday). nrf_drv_config.h is no longer used in SDK 12.x, you should only include sdk_config.h. Where did you get the example BLE_APP_UART from?

Best regards,

Jørgen
