10.3 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 are listed below. To view all available tools and software for C2000™ real-time control MCUs, visit the C2000 MCU Tools and Software page.

Design Kits and Evaluation Modules

C2000 Delfino MCUs F28377S LaunchPad Development Kit
The C2000™ Delfino™ MCUs LaunchPad™ development kit is an inexpensive evaluation platform that provides designers with a low-cost development kit for high-performance digital control applications. This tool provides a great starting point for development of many high-end digital control applications such as industrial drives and automation; power line communications; solar inverters; and more.

Delfino C28343 controlCARD
The C28343 controlCARD allows users to easily evaluate all the functionality of the 200-MHz C28343 floating-point controller and is compatible with existing controlCARD tool kits. The card provides all the chip support necessary, needing only a 5-V supply to be fully functional. The controlCARD also has two onboard 12-bit ADCs and a 64KB EEPROM for nonvolatile program storage. Based on the standard DIM100 controlCARD form factor, it is pin-compatible with other C2000 controlCARDs.

Software

C2000 DesignDRIVE Software for Industrial Drives and Motor Control
The DesignDRIVE platform combines software solutions with DesignDRIVE Development Kits to make it easy to develop and evaluate solutions for many industrial drive and servo topologies. DesignDRIVE offers support for a wide variety of motor types, sensing technologies, position sensors and communications networks, including specific examples for vector control of motors, incorporating current, speed and position loops, to help developers jumpstart their evaluation and development. Based on the real-time control architecture of TI’s C2000™ microcontrollers (MCUs), DesignDRIVE is ideal for the development of industrial inverter and servo drives used in robotics, computer numerical control machinery (CNC), elevators, materials conveyance and other industrial manufacturing applications.

powerSUITE Digital Power Supply Software Frequency Response Analyzer Tool for C2000™ MCUs
The Software Frequency Response Analyzer (SFRA) is one of several tools included in the powerSUITE Digital Power Supply Design Software Tools for C2000™ Microcontrollers. The SFRA includes a software library that enables developers to quickly measure the frequency response of their digital power converter. The SFRA library contains software functions that inject a frequency into the control loop and measure the response of the system using the C2000 MCUs’ on-chip analog to digital converter (ADC). This process provides the plant frequency response characteristics and the open loop gain frequency response of the closed loop system. The user can then view the plant and open loop gain frequency response on a PC-based GUI. All of the frequency response data is exported into a CSV file, or optionally an Excel® spreadsheet, which can then be used to design the compensation loop using the Compensation Designer.

C2000Ware for C2000 MCUs
C2000Ware for C2000™ microcontrollers is a cohesive set of development software and documentation designed to minimize software development time. From device-specific drivers and libraries to device peripheral examples, C2000Ware provides a solid foundation to begin development and evaluation of your product.

Development Tools

C2000 Gang Programmer
The C2000 Gang Programmer is a C2000 device programmer that can program up to eight identical C2000 devices at the same time. The C2000 Gang Programmer connects to a host PC using a standard RS-232 or USB connection and provides flexible programming options that allow the user to fully customize the process.

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.
