5.2 Tools and Software

Tools

    F28379D development kit for C2000™ Delfino MCU controlCARD™TMDSCNCD28379D is an HSEC180 controlCARD based evaluation and development tool for the F2837xD, F2837xS, and F2807x series in the TI MCU. controlCARDs are ideal to use for initial evaluation and system prototyping. controlCARDs are complete board-level modules that utilize one of two standard form factors (100-pin DIMM or 180-pin HSEC ) to provide a low-profile single-board controller solution. For first evaluation controlCARDs are typically purchased bundled with a baseboard or bundled in an application kit.

Software

    MotorControl software development kit (SDK) for C2000™MotorControl 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.
