User's Guide SWRU376A – June 2014 – Revised June 2014 CC3200 SimpleLink™ Wi-Fi® and IoT Solution With MCU LaunchPad™ Getting Started Guide This guide is intended to assist users in the initial setup and demonstration of the Getting Started with WLAN Station application. The guide explains how to install an Integrated Development Environment (IDE), and then compile, download and debug Getting Started with WLAN Station. 1 Introduction 1.
Getting Started www.ti.com 2 Getting Started 2.1 Download and Install Software Download and install the following software: • CC3200 SDK package. – This guide assumes the use of the default installation folder C:\TI\CC3200SDK\. 2.2 Configure Board The jumpers on the CC3200-LAUNCHXL should be connected as shown in Figure 1. It may be necessary to move a jumper from P58-VCC to SOP2. Figure 1. Jumpers on the CC3200-LAUNCHXL 2.3 Install USB Driver 1.
Getting Started www.ti.com Figure 2. Windows Device Manager 3. Right click on the first instance of “USB <-> JTAG/SWD” and select “Update Driver Software…” 4. Select “Browse my computer for driver software.” Figure 3. Update Driver Software 5. Fill the search path as C:\TI\CC3200SDK\cc3200-sdk\tools\ftdi, and press next. There is no need to restart the PC.
Getting Started www.ti.com Figure 4. Browse for Driver Software 6. Repeat the above three steps for the other instance of "USB <-> JTAG/SWD." 7. Repeat the same steps for the instance of “USB Serial Port” that should have appeared as shown in Figure 5. Figure 5. USB Serial Port 8. The CC3200-LAUNCHXL will now be visible in the Device Manager as shown in Figure 6. Note the COM port number that appears.

Compile, Download, and Debug www.ti.com 3 Compile, Download, and Debug The CC3200 SDK supports CCS 6.0, IAR 7.10.3 and GCC IDE/compiler. The example shown here is Getting Started with WLAN Station, and performs the following functions: 1. Switches to Station mode if the device is in AP mode. 2. Connects to the user's Access Point (default SSID is ‘cc3200demo’). If the connection to the AP is successful, the red LED (D7) will switch on. 3. Pings the user's Access Point.
Compile, Download, and Debug 2. 3. 4. 5. 6. www.ti.com Open the App Center from the Help->Getting Started screen. Search 'CC3200' in the App Center to find 'TI-RTOS for SimpleLink' and 'CC3200 Add-On' Select TI-RTOS Select the CC3200 Add-On Press 'Install Software' Figure 8.
