www.ti.com Appendix A Summary of Using Code Composer Studio v3.3 In this appendix, we describe basic steps how to use Code Composer Studio v3.3, or CCS, to compile firmware for UCD3138. A design flow is described while detailed steps for firmware code creation, and firmware debugging along with hardware are obviously beyond the scope of this user’s guide and this appendix. A.1 Set up Code Composer Studio v3.3 for UCD3138 The recommended version of Code Composer Studio is v3.3.
Build and Compile a Project using Code Composer Studio A.2 www.ti.com 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. On the matter how to create a project, please refer to reference 2, Code Composer Studio Development Tools v3.3 – Getting Started Guide. The example below is to describe typical compile process for UCD3138 firmware. The project file name is Cyclone.pjt in a folder named Training 02.
