8 Targeting Tornado for Real-Time Applications
8-2
Introduction
This chapter describes how to create real-time programs for execution under
VxWorks, which is part of the Tornado environment.
The VxWorks real-time operating system is available from Wind River
Systems, Inc. It provides many UNIX-like features and comes bundled with a
complete set of development tools.
Note Tornado is an integrated environment consisting of VxWorks (a
high-performance real-time operating system), application building tools
(compiler, linker,
make, and archiver utilities), and interactive development
tools (editor, debugger, configuration tool, command shell, and browser).
This chapter discusses the run-time architecture of
VxWorks-based real-time programs generated by the Real-Time Workshop and
provides specific information on program implementation. Topics covered
include:
• Configuring device driver blocks and makefile templates
• Building the program
• Downloading the object file to the VxWorks target
• Executing the program on the VxWorks target
• Using Simulink external mode to change model parameters and download
them to the executing program on the VxWorks target
• Using the StethoScope data acquisition and graphical monitoring tool, which
is available as an option with VxWorks. It allows you to access the output of
any block in the model (in the real-time program) and display the data on the
host.
Confirming Your Tornado Setup Is Operational
Before beginning, you must install and configure Tornado on your host and
target hardware, as discussed in the Tornado documentation. You should then
run one of the VxWorks demonstration programs to ensure you can boot your
VxWorks target and download object files to it. See the Tornado User’s Guide
