VisSim/Embedded Controls Developer

The Smarter, Faster Way for Embedded Control Design

The VisSim/Embedded Controls Developer software is a development environment for the rapid prototyping and development of embedded control systems. It supports the TI MSP430, F24x, LF240x, F2812, C5510, C6713 and associated development boards from Spectrum Digital and SoftBaugh.

VisSim/ECD embedded target support includes automatic C-code generation, compile and link. The VisSim "DSP interface" block will download and maintain real-time communication with the embedded target from the VisSim diagram as the embedded application runs on the target. This allows real-time gain changes on the target from within VisSim as well as plotting of target responses. Best of all, these tasks can be done without writing a line of code! VisSim DSP target support also lets you create a completely stand-alone target for final FLASH burn.

VisSim is unique in its ability to generate small memory footprint target files. For example. a closed loop PID control with encoder input and PWM output and one Digital output line take 2.5K ROM and 500 bytes RAM and can sample at up to 300 KHz on the F2812.

What's included in VisSim/Embedded Controls Developer

• VisSim/Fixed Point™ block set performs simulation and efficient code generation of scaled fixed point operations. Overflow and precision loss effects are easily seen and corrected at simulation time. Auto-scaling speeds fixed point development. In-line code generation creates fast target code.
• Peripheral Blocks to generate code for on-chip devices, including:
  • analogue and digital I/O, quadrature encoder inputs, event capture (up to 1 MHz resolution)
  • CAN 2.0 bus with six mailboxes, serial port, 4 simple PWM outputs, SPI, Watchdog
  • 2 six-channel space vector PWM outputs with deadband, Device I/O ports, interrupts
• TI C2000 Digital Motor Control (DMC) Block Set supports simulation and code generation of efficient, hand-coded assembler for motion control systems based on AC Induction, Brushless DC, Permanent Magnet Synchronous motors
• Automatic C-code generation of production quality fixed-point code, compile, link and JTAG download to the TI MSP430 / F24x / LF240x / F281x / C5510 / C6713
• View Responses and interactively change gains in the VisSim GUI while your algorithm executes on the target
• VisSim-Code Composer Studio (CCS) plug-in for automatic CCS project creation
• TI C2000 CAN Bus Support
• Serial port based LCD display support
• Flash Burn support tracks processor speed and PLL multiple to safely burn your standalone controller to Flash

VisSim Supported Target Boards:

In the words of Todd Solak, Worldwide Marketing Manager of the Digital Controls System Group at leading DSP manufacturer Texas Instruments, "The combination of the VisSim/Embedded Controls Developer software and TI's C2000 DSPs provides designers with an excellent embedded DSP control platform."

Guohui Yuan, Senior Controls Engineer at WaveCrest Corporation says of VisSim/ECD: "Thanks to VisSim/ECD, we shortened software development time for our BLDC mining pump motor by at least several months. We did coding and testing for the LF2406 Semikron inverter boards, performance tests for the motor, and PID tuning for system optimization, all in VisSim. Choosing VisSim is one of the smartest investments WaveCrest has ever made."
