Hi Nordic team,
I am trying to enable I2C driver in SAADC example which is located in examples\peripheral\saadc\pca10040\blank\arm5_no_packs
As you can see I am using Keil V5
This example is working perfectly. The issue is when I am trying to use TWI in this.
nrf_drv_twi.c, nrfx_twi.c and nrfx_twim.c are added to project.
sdk_config.h didn't have the option to enable TWI, so I added following to sdk_config.h

// <e> NRFX_TWIM_ENABLED - nrfx_twim - TWIM peripheral driver
//==========================================================
#ifndef NRFX_TWIM_ENABLED
#define NRFX_TWIM_ENABLED 1
#endif
// <q> NRFX_TWIM0_ENABLED - Enable TWIM0 instance
#ifndef NRFX_TWIM0_ENABLED
#define NRFX_TWIM0_ENABLED 1

// <o> NRFX_TWIM_DEFAULT_CONFIG_FREQUENCY - Frequency
Following is being included in the code

#include "nrf_drv_twi.h"
#include "nrf_twi.h"
#include "nrf_twim.h"
I have read through a lot of topics, everywhere above two solutions are suggested but I am still getting the following errors
