5.2 Tools and Software

Tools

    CCSTUDIOCode Composer Studio is an integrated development environment (IDE) for TI's microcontrollers and processors. The IDE comprises a suite of tools used to develop and debug embedded applications. Code Composer Studio is available for download across Microsoft® Windows®, Linux®, and macOS® desktops. The software can also be used in the cloud by visiting the TI developer zone.
    TMS320F2800137 LaunchPad™ development kit for C2000™ real-time MCULAUNCHXL-F2800137 is a development board for TI C2000™ real-time microcontrollers series of F280013x devices. This kit is an excellent choice for initial evaluation and prototyping, and provides a standardized and easy-to-use platform to develop the next application. This extended version LaunchPad™ development kit offers extra pins for development and supports the connection of two BoosterPack™ plug-in modules. As part of the vast TI MCU LaunchPad ecosystem, this tool is also cross-compatible with a broad range of plug-in modules.

Software

    MotorControl Software Development Kit (SDK) for C2000™ MCUMotorControl SDK for C2000™ microcontrollers (MCU) is a cohesive set of software infrastructure, tools, and documentation designed to minimize C2000 real-time controller-based motor control system development time targeted for various three-phase motor control applications. The software includes firmware that runs on C2000 motor control evaluation modules (EVMs) and TI reference designs which are targeted for industrial drives, robotics, appliances, and automotive applications. MotorControl SDK provides all the needed resources at every stage of development and evaluation for high performance motor control applications.
