9.4 Tools and Software

TI offers an extensive line of development tools. Some of the tools and software to evaluate the performance of the device, generate code, and develop solutions follow. To view all available tools and software for C2000™ real-time control MCUs, visit the C2000 real-time control MCUs – Design & development page.

Development Tools

LAUNCHXL-F280025C
LAUNCHXL-F280025C is a low-cost development board for TI C2000™ Real-Time Controllers series of F28002x devices. Ideal for initial evaluation and prototyping, it provides a standardized and easy-to-use platform to develop your next application. This extended version LaunchPad™ development kit offers extra pins for evaluation and supports the connection of two BoosterPack™ plug-in modules.

F280025 controlCARD
The F280025 controlCARD is an HSEC180 controlCARD based evaluation and development tool for the C2000™ F28002x series of microcontroller products. 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.

C2000Ware for C2000™ MCUs is a cohesive set of software and documentation created to minimize development time. It includes device-specific drivers, libraries, and peripheral examples.

Digital Power SDK
Digital Power SDK is a cohesive set of software infrastructure, tools, and documentation designed to minimize C2000 MCU-based digital power system development time targeted for various AC-DC, DC-DC and DC-AC power supply applications. The software includes firmware that runs on C2000 digital power evaluation modules (EVMs) and TI designs (TIDs), which are targeted for solar, telecom, server, electric vehicle chargers and industrial power delivery applications. Digital Power SDK provides all the needed resources at every stage of development and evaluation in a digital power applications.

Motor Control SDK
Motor Control SDK is a cohesive set of software infrastructure, tools, and documentation designed to minimize C2000 MCU-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 designs (TIDs), which are targeted for industrial drive and other motor control, Motor Control SDK provides all the needed resources at every stage of development and evaluation for high-performance motor control applications.

Code Composer Studio™ (CCS) Integrated Development Environment (IDE) for C2000 microcontrollers
Code Composer Studio is an integrated development environment (IDE) that supports TI's Microcontroller and Embedded Processors portfolio. Code Composer Studio comprises a suite of tools used to develop and debug embedded applications. It includes an optimizing C/C++ compiler, source code editor, project build environment, debugger, profiler, and many other features. The intuitive IDE provides a single user interface taking the user through each step of the application development flow. Familiar tools and interfaces allow users to get started faster than ever before. Code Composer Studio combines the advantages of the Eclipse software framework with advanced embedded debug capabilities from TI resulting in a compelling feature-rich development environment for embedded developers.

SysConfig System configuration tool
SysConfig is a comprehensive collection of graphical utilities for configuring pins, peripherals, radios, subsystems, and other components. SysConfig helps you manage, expose and resolve conflicts visually so that you have more time to create differentiated applications. The tool's output includes C header and code files that can be used with software development kit (SDK) examples or used to configure custom software. The SysConfig tool automatically selects the pinmux settings that satisfy the entered requirements. The SysConfig tool is delivered integrated in CCS, as a standalone installer, or can be used via the dev.ti.com cloud tools portal. For more information about the SysConfig system configuration tool, visit the System configuation tool page.
