Development Tools and Software

For the most up-to-date list of development tools and software, see the CC3220 Tools & Software product page. Users can also click the "Alert Me" button on the top right corner of the CC3220 Tools & Software page to stay informed about updates related to the CC3220MOD device.

Development Tools

    Pin Mux ToolThe supported devices are: CC3200 and CC3220x.

    The Pin Mux Tool is a software tool that provides a graphical user interface (GUI) for configuring pin multiplexing settings, resolving conflicts and specifying I/O cell characteristics for MPUs from TI. Results are output as C header/code files that can be imported into software development kits (SDKs) or used to configure customers' custom software. Version 3 of the Pin Mux Tool adds the capability of automatically selecting a mux configuration that satisfies the entered requirements.

    SimpleLink Wi-Fi® Starter ProThe supported devices are: CC3100, CC3200, CC3120R, and CC3220x.

    The SimpleLink™ Wi-Fi® Starter Pro mobile App is a new mobile application for SimpleLink provisioning. The app goes along with the embedded provisioning library and example that runs on the device side (see SimpleLink™ Wi-Fi® CC3120 SDK plugin and TI SimpleLink™ Wi-Fi® CC3220 Software Development Kit (SDK)). The new provisioning release is a TI recommendation for Wi-Fi provisioning using SimpleLink Wi-Fi products. The provisioning release implements advanced AP mode and SmartConfig™ technology provisioning with feedback and fallback options to ensure successful process has been accomplished. Customers can use both embedded library and the mobile library for integration to their end products.

    SimpleLink Wi-Fi® Radio Testing ToolThe supported devices are: CC3100, CC3200, and CC3220x.

    The SimpleLink™ Wi-Fi® Radio Testing Tool is a Windows-based software tool for RF evaluation and testing of SimpleLink Wi-Fi CC3120 and CC3220 designs during development and certification. The tool enables low-level radio testing capabilities by manually setting the radio into transmit or receive modes. Using the tool requires familiarity and knowledge of radio circuit theory and radio test methods.

    Created for the Internet of Things (IoT), the SimpleLink Wi-Fi CC31xx and CC32xx family of devices include on-chip Wi-Fi, Internet, and robust security protocols with no prior Wi-Fi experience needed for faster development. For more information on these devices, visit SimpleLink Wi-Fi® family, Internet-on-a chip™ solutions.

    CC3220 Software Development Kit (SDK) The CC3220x device is supported.

    The CC3220 SDK contains drivers, many sample applications for Wi-Fi features and Internet, as well as documentation needed to use the CC3220 Internet-on-a-chip solution. This SDK can be used with TI’s MSP432P401R LaunchPad™ development kit, or with the SimpleLink Studio, a PC tool that allows MCU development with CC3220. You can also use the SDK as example code for any platform. All sample applications in the SDK are supported on TI’s MSP432P401R ultra-low-power MCUs with Code Composer Studio™ IDE and TI-RTOS. In addition, many of the applications support IAR.
