www.ti.com Appendix A Summary of Using Code Composer Studio v3.3 This appendix describes the basic steps on how to use Code Composer Studio v3.3, or CCS, to compile firmware for UCD3138. The design flow describes detailed steps for firmware code creation and firmware debugging. A.1 Set Up Code Composer Studio v3.3 for UCD3138 The recommended version of Code Composer Studio is version 3.3 (v3.3). After completing the CCS v3.
Build and Compile a Project Using Code Composer Studio www.ti.com A.2 Build and Compile a Project Using Code Composer Studio After a project is created with all source codes developed, one can compile the project using CCS. A.2.1 Creating a Project The example below describes the typical compile process for UCD3138 firmware. The project file name is Cyclone.pjt and it is located in the folder named Training 02. The final result of the compile process is a file with the file extension of .x0.
