9 Targeting DOS for Real-Time Applications
9-2
Introduction
This chapter provides information that pertains specifically to using the
Real-Time Workshop in a DOS environment.
This chapter includes a discussion of:
• DOS-based Real-Time Workshop applications
• Supported compilers and development tools
• Device driver blocks — adding them to your model and configuring them for
use with your hardware
• Building the program
The DOS target creates an executable using Watcom for DOS (i.e., a computer
running the DOS operating system and not a Microsoft Windows DOS
command prompt). This executable installs interrupt service routines and
effectively takes over the computer, which allows the generated code to run in
real-time. If you want to run the generated code in real-time under Microsoft
Windows, you should use the Real-Time Windows Target, which is a separate
product from the Real-Time Workshop. See the Real-Time Windows Target
User’s Guide for more information about this product.
