UCF Innovation Lab CC3200 Camp

In this camp, you will learn how to program a CC3200 LaunchPad to upload data (temperature, vibration) to a server on the web. The CC3200 is a chip made by Texas Instruments that supports wireless connectivity. A popular term for devices made with these chips is an Internet of Things (IoT) device.

The basic steps to accomplish this lab are listed below:

1. Unpack and set up CC3200 LaunchPad
2. Install Energia IDE (Compiler) for the CC3200 LaunchPad
3. Download example software from UCF Innovation Lab GitHub Repository
4. Program the CC3200 LaunchPad with the example software
5. Modify software to include your home access point SSID and password

Unpack and Set Up CC3200 LaunchPad

Customize Board for Your Access Point

In this section, you will configure the board to connect to your home access point. You will need the SSID and Password of your access point. This information will be inserted into the program.

Network Configuration

If you are using a Wi-Fi BosoterPack or LaunchPad, the following variables need configuration:

char ssid[] = "<ssid>";
char pass[] = "<WPA password>";

Just fill in the SSID and password of the Wi-Fi hotspot, you should be good to go.
