Real-Time Workshop User's Guide

Asynchronous Support

Introduction

The Interrupt Templates are blocks that you can use as templates for building your own asynchronous interrupts.

This chapter include the following topics:

• Interrupt Handling. Blocks that let you model synchronous/asynchronous event handling, including interrupt service routines.
• Creating a Customized Asynchronous Library. Guidelines for creating your own asynchronous blocks, using templates provided.

The Interrupt Templates library is part of the Real-Time Workshop library. You can access the Real-Time Workshop library via the Simulink Library Browser as shown in Figure 15-1. Alternatively, you can access the Real-Time Workshop library by typing the command

rtwlib

at the MATLAB command prompt.

Note that, depending on which MathWorks products you have installed, your browser may show a different collection of libraries.

Other sublibraries in the Real-Time Workshop library are:

• DOS Device Drivers: Blocks for use with DOS. See Chapter 13, Targeting DOS for Real-Time Applications for information.
• Custom Code Blocks: Blocks that allow you to insert custom code into the generated source code files and/or functions associated with your model. See Chapter 14, Custom Code Blocks. for information.
• S-Function Target: The S-Function Target sublibrary contains only one block type, the RTW S-Function block. This block is intended for use with generated S-functions. See Chapter 10, The S-Function Target for more information.
• VxWorks Support: A collection of blocks that support VxWorks (Tornado). See Chapter 12, Targeting Tornado for Real-Time Applications for information on VxWorks.
