Procedure

1. Create a new folder on desktop location.

2. Open ccstudio on desktop.

3. Browse the workspace location

    Click on browseàdesktopàselect created folderàok button.

4. ccs wizard is opened

     Click on projectànew ccs projectàtarget [select Tiva c series].

5. Select microcontroller “Tiva TM4C123GH6PM”, click on connection and select “Stellaris in-circuit debug interface”.                                    

6. Name the project in project name bar and click on finish button.

7. Click on restore button on left side and then enter the programà save button.

8. Now unfold the project and right click on project and select properties.

9. Select include optionsàaddàbrowseàmy computeràlocal disc càtià Tivaware_c_series_2.1.2.111àok. Now directory path is added to project then click on ok button.

10. Select projectà Right click on project à add files à select local disc cà  select tià Tivaware_c_series_2.1.2.111 àselect driverlib à ccs à debug à driverlib.lib à open button.

11. Select copy files and click ok button. Now driver library file is added to the project.                                                                                                                                    

12. To build the project click on Build button.

13. After building the project is finished. Connect TM4C launch pad to pc using USB cable.
