Description
The VisSim/Embedded Controls Developer
software is an environment for model based
development of embedded controllers for Texas
Instruments DSPs and microprocessors.
It simulates and generates scaled, fixed-point
ANSI C code for VisSim diagrams, including onchip
peripherals like SCI, SPI, CAN, ePWM, eQEP,
eCAP, ADC, DAC, SD16, segment LCD. It supports
the Texas Instruments MSP430, F243, LF240x,
F281x, F280x, C5510, C6713, as well as
development boards from Spectrum Digital,
SoftBaugh and Innovative Integrations. It lets you
compile, link and download the diagram to the
target DSP all from within the VisSim environment.
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 standalone
target for final flash burn.
The software simulates the effects
of scaled, fixed-point truncation and
precision loss. It logs minimum and
maximum values observed during
simulation, and performs automatic programming of on-chip peripherals
for TI F243 and F2407 EVMs and
LF2407 eZdsp evaluation boards. It
uses a JTAG hotlink for downloading,
and real-time communication for
plotting responses and interactively
changing parameters during DSP
execution.
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: Professional VisSim, VisSim/fixed-point blocks and
design tools, TI C2000 Digital Motor Control block
set, TI C2000 CAN bus support, peripheral blocks that generate
code for on-chip devices, automatic C-code generation, VisSim/Code Composer Studio
plug-in for automatic project
creation, serial port based LCD display
support and fixed-point digital filter design.
