3 Firmware Installation
3.1 Installing Code Composer Studio
CCS versions 5.x.x and 6.x.x have been used and tested for DRV832XX reference code. An authorized
version can be installed from
www.ti.com/tool/ccstudio .
NOTE: A myTI login account is required to download CCS as well as the SDK package. This section
describes the installation procedure for CCS5.4; however, installing other versions of CCS
v5.x including CCS v6.x is similar.
After following the required steps to download the CCS installer, the ccs_setup_5.4.0.00091.exe file
should be located in the specified download directory.
Figure 8 shows this file.
Figure 8. Downloaded Executable for Code Composer Studio Installation
Follow the installation process listed:
Step 1. Run the installer by double clicking the ccs_setup_win32.exe file.
