Keil: include problem with TWI file

Keil: include problem with TWI filehttps://devzone.nordicsemi.com/f/nordic-q-a/20998/keil-include-problem-with-twi-fileHello I adapted the ble_app_uart with twi functionality. Therefore I included the "app_twi.h" which includes the "nrf_drv_twi.h" But as visible in the picture, the "nrf_drv_twi.c" doesn't show up in the tree of project files in the "nrf_Drivers" branchen-USTelligent Community 13Fri, 31 Mar 2017 10:45:35 GMTRE: Keil: include problem with TWI filehttps://devzone.nordicsemi.com/thread/82066?ContentTypeID=1Fri, 31 Mar 2017 10:45:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:109536cd-0c69-40d8-ad59-afcc7235f347MartinBL<p>Make sure you add the file: "sdk_folder\components\drivers_nrf\twi_master\nrf_drv_twi.c" to your project. This is where your missing functions are defined. You might also need to enable TWI in the sdk_config.h file.</p><div style="clear:both;"></div>
