For more details on where to download the latest IDE, see Section 4.3. The CC3200 programmer's guide (SWRU369) has detailed information on software environment setup, with examples. Refer to this document for further details on the software sample examples. 3.1.1 CCS CCS 6.0 or higher is required. When CCS has been launched, and a workspace directory chosen, use Project → Import Existing CCS Eclipse Project. Direct it to the desired demo’s project directory containing main.c. 3.1.2 IAR IAR 6.70 or higher is required. To open the demo in IAR, choose File → Open → Workspace…, and direct it to the *.eww workspace file inside the \IAR subdirectory of the desired demo. All workspace information is contained within this file. The subdirectory also has an *.ewp project file; this file can be opened into an existing workspace, using Project → Add-Existing-Project…. 4 Additional Resources 4.1 LaunchPad Kit Wiki Most updated information is available on the CC3200 Wiki page. 4.2 Information on the CC3200 For more information on CC3200, visit the product page (http://www.ti.com/product/cc3200), which includes the data sheet (SWAS032) and key documents such as the technical reference manual (SWRU367) and Wiki (http://www.ti.com/simplelinkwifi-wiki). These resources contain information on getting started, hardware details, software details including porting information, testing and certification, support, and the CC3200 community. 4.3 Download a Development Environment Although the files can be viewed with any text editor, more can be done with the projects if they are opened with a development environment such as Code Composer Studio (CCS), IAR, or Energia. CCS and IAR are each available in a full version, or a free, code-size-limited version. The full out-of-box demo cannot be built with the free version of CCS or IAR (IAR Kickstart), due to the code-size limit. To bypass this limitation, a code-size-limited CCS version is provided that has most functionality integrated into a library. The code built into the library is able to be viewed by the user, but it cannot be edited. For full functionality, download the full version of either CCS or IAR. 4.4 The CC3200 Code Examples The user's guide for each example can be found within the Software Development Kit (SDK) or on the SimpleLink Wiki. 4.5 CC3200 Application Notes There are many application notes with practical design examples and topics located at the SimpleLink(TM) Wi-Fi(R) Wiki page and the main landing page.
