TMS320C24x Evaluation
Module (EVM)

The new TMS320C24x Evaluation Module from Texas Instruments gives designers of motor and motion control applications a complete and cost-effective way take their designs from concept to production. At a suggested price of $1495, the kit is the easiest way to fully evaluate and begin developing code for embedded, real-time motor and motion control systems. The ‘C24x EVM builds on TI’s industry-leading array of development tools that allow designers to take full advantage of the benefits of DSP-based systems.

Utilizing the TMS320F240, the ‘C24x EVM gives designers access to the industry’s most powerful DSP specifically optimized for motor control applications. The highly integrated 20-MIPS DSP represents an important breakthrough over traditional microcontroller and general-purpose DSP processor solutions. The 'C240s combination of math processing capabilities and integrated motor control peripherals allow designers to reduce overall system cost while increasing system performance.

What’s in the EVM?

The ‘C24x EVM comes complete with a C24x evaluation board, emulator, fixed-point assembly language tools, an EVM debugger, power supply, sample applications code and complete documentation.

Evaluation Board

The ‘C24x evaluation board features the TMS320F240 16-bit, fixed-point DSP, an onboard digital-to-analog converter (DAC) with 12-bit resolution and 128K words of SRAM for faster code development and an RS-232 serial port direct PC interface.

TMS320F240

TI designed the ‘C24x in response to industry demand for more sophisticated digital motor control solutions. New designs using inexpensive AC induction, DC brushless or switched reluctance motors can be made more efficient with the high-performance processing delivered by DSPs.

The ‘F240 complements the ‘C24x generation by adding 16K words of flash memory, which eases the development process with easy in-system reprogrammabilty. Other features of the device that set it apart for high-performance motor control applications include an optimized event manager that provides all pulse-width modulation (PWM) and I/O features to drive all motor types, an SPI and SCI for serial communications, 28 bi-directional I/O pins, a watchdog timer and integrated dual 10-bit A/D converters.

DAC

Complete with 12-bit resolution, the 4-channel DAC provides important development advantages for motor control systems, allowing designers to perform real-time analysis and debug of code.

128K Words SRAM

The onboard memory enables increased debugging flexibility by allowing designers to set multiple break points in their software. Increased data acquisition capabilities are also possible with this external memory.

Emulator

Developed by Spectrum Digital Incorporated, the XDS510PP emulator utilizes the JTAG scan path to communicate with the ‘F240 DSP. This full featured, in-circuit emulator easily connects to the parallel port of your PC and provides complete non-intrusive debug capabilities. As product development progresses, the emulator has the flexibility to be used with the designer's own 'C24x-based target system.

‘C24x EVM Debugger

Compatible with the XDS510PP emulator and TI C compilers, the ‘C24x EVM debugger can be used with all devices in the ‘C24x generation to reduce overall development time. Features single stepping that allows developers to execute one line at a time for more system code visibility; breakpoints to stop code on any single line; mnemonic assembly that converts machine code back to assembly code; and variable watch windows that can display program data in multiple formats.

Assembly Language Tools

The assembler and linker tools translate assembly source code into a single Common Object File Format (COFF) for download to the ‘F240. Other EVM assembly language tools include absolute and cross-reference listers and a hex conversion utility.

Applications Code

The EVM includes applications code to test different on-board peripherals. In addition, customers can download a growing list of additional applications code:

dac.exe	Outputs four sine waves on the EVM DAC, each generated through a look up table and interpolation.
dips.exe	Demonstrates fetching data from I/O space from the DIP switches, then returns the data to the I/O space to the LEDs on the board.
leds.exe	Familiarizes the user with manipulating the I/O mapped LEDs on the F240 EVM development board.
mem_test.exe	Checks the memory locations and external data memory of the board using a checker board method.

Expandability

As with all TMS320 DSPs, designers using the ‘C24x EVM benefit from the industry’s largest network of third parties. The kit’s board features four connectors that can be used to link it to a growing number of third-party daughter cards, including products from Spectrum Digital and International Rectifier.
