10.2 Tools and Software

The CC2755x20 device is supported by a variety of hardware development and software resources.

    Development Kit CC2755P20 LaunchPad™ Development Kit

    The CC2755P20 LaunchPad™ Development Kit enables development of high-performance wireless applications that benefit from low-power operation. The kit features the CC2755P20 SimpleLink Wireless MCU, which allows you to quickly evaluate and prototype 2.4GHz Bluetooth Low Energy wireless applications for up to +20dBm transmit output power. The kit works with the LaunchPad ecosystem, easily enabling additional functionality like sensors, display, and more.
    Software SimpleLink™ low power software development kit (SDK)

    The SimpleLink low power software development kit (SDK) provides a complete package for the development of wireless applications on the CC27xx family of devices. The SDK includes a comprehensive software package for the CC2755x20 device, including the following protocol stacks:

    The SimpleLink low power SDK is part of TI’s SimpleLink MCU platform, offering a single development environment that delivers flexible hardware, software and tool options for customers developing wired and wireless applications. For more information about the SimpleLink MCU Platform, visit https://www.ti.com/simplelink.
    Development ToolsCode Composer Studio™ Integrated Development Environment (IDE)

    Code Composer Studio (CCStudio™) is an integrated development environment (IDE) that supports TI's Microcontroller and Embedded Processors portfolio. It comprises a suite of tools used to develop and debug embedded applications. CCStudio IDE is available as desktop or cloud-based applications.

    CCStudio IDE integrates industry-standard AI agents and models to accelerate code development, system configuration, and debug. It has support for all SimpleLink Wireless MCUs and includes support for EnergyTrace™ software (application energy usage profiling). A real-time object viewer plugin is available for Free-RTOS.

    CCStudio IDE is provided free of charge when used in conjunction with the XDS debuggers included on a LaunchPad Development Kit.
    IAR Embedded Workbench® for Arm®

    IAR Embedded Workbench® is a set of development tools for building and debugging embedded system applications using assembler, C and C++. It provides a completely integrated development environment that includes a project manager, editor, and build tools. IAR has support for all SimpleLink Wireless MCUs. It offers broad debugger support, including XDS110, IAR I-jet™ and Segger J-Link™. IAR is also supported out-of-the-box on most software examples provided as part of the SimpleLink SDK.

    A 30-day evaluation or a 32KB size-limited version is available through iar.com.

    SmartRF™ Studio

    SmartRF™ Studio is a Windows® application that can be used to evaluate and configure SimpleLink Wireless MCUs from Texas Instruments. The application will help designers of RF systems to easily evaluate the radio at an early stage in the design process. It is especially useful for generation of configuration register values and for practical testing and debugging of the RF system. SmartRF Studio can be used either as a standalone application, through a command line interface to enable more automation or together with applicable evaluation boards or debug probes for the RF device. Features of the SmartRF Studio include:

    • Link tests send and receive packets between nodes
    • Antenna and radiation tests set the radio in continuous wave TX and RX states
    • Export radio configuration code for use with the TI SimpleLink SDK RF driver
    • Custom GPIO configuration for signaling and control of external switches

    CCS UniFlash

    CCS UniFlash is a standalone tool used to program on-chip flash memory on TI MCUs. UniFlash has a GUI, command line, and scripting interface. CCS UniFlash is available free of charge.
