MAX-IDE Simulator User's Guide for the MAXQ

Microcontrollers

Sep 22, 2006

Abstract: This application note provides useful references and describes how to use the MAX-IDE toolset

to build applications for MAXQ® microcontrollers. It specifically explains how to use the MAX-IDE

simulator.

Introduction

The MAX-IDE is an easy-to-use Windows®-based development environment and tool set that gives

designers software simulators, emulators and debugging capabilities. Using MAX-IDE, developers can

create embedded applications for the MAXQ microcontroller.

Overview

The MAX-IDE toolset provides the following features:

1. MAXQ assembler. For the MAXQ microcontroller instruction set, see Section 18.0 of the MAXQ

Family User's Guide (PDF) available for download.

2. Project manager

3. Text editor

4. Viewer for processor memory (utility ROM/code/data) and registers

5. Debugger with the ability to single-step and set breakpoints

6. Simulators for different MAXQ devices

7. Statistical reporting for machine cycles, execution time, and other parameters

The following files are installed as part of the installation:

1. GenericIDE.exe: This is a MAX-IDE executable that provides the Windows-based integrated

development environment including the text editor, project manager, and debugger.

2. MAX-IDE.hlp: This file contains the MAX-IDE help information. Users can access the contents of

this file through the MAX-IDE's help menu.

3. MaxQGS.dll: This is the DLL file for a MAXQ device simulator.

4. Macro.exe: This is the executable file for the macro preprocessor. The macro preprocessor takes

the assembly source file as an input and converts equates to numeric values and macros to inline

code.

5. MaxQAsm.exe: This is the MAXQ assembler. The assembler supports the complete instruction set

of MAXQ. It takes the assembly source file (.asm) as an input and produces an Intel hex file (.hex)

and a list file (.lst).

Figure 2. Use the project manager and editor windows to create a new file. Step 3: Before adding this new file to the project, you need to save this file. Choose File→Save Untitled1 which opens the Save As dialog box. Create a new folder, MAXIDE, and save the file to the MAXIDE folder as hex_to_asc.asm. Step 4: To add the source file that we just created to the project, choose Project→Add Files. This will open up the Open dialog box.

Figure 3. The MAXQ Simulator is accessed from the Device menu. The MAXQ Simulator supports MAXQ10, MAXQ20, and MAXQ30 devices. To select the device, click on Device→Options, as illustrated in Figure 4.

Figure 4. The Options window asks you to choose a MAXQ device. The drop-down menu in Figure 4 shows the available devices, which consist of specific MAXQ devices (e.g., MAXQ2000) and generic devices (e.g., MAXQ10—Generic for a MAXQ10 architecture). Note that when you choose a specific device like the MAXQ2000, the Processor is selected automatically. If, for example, the MAXQ2000 is selected, the MAXQ20 would be selected automatically as its processor.

Figure 5. The Debug Windows with the breakpoint are indicated by the green arrow and line. Step 11: Open up the registers window by clicking on Window→Show→Registers from the Window menu. Select SYSTEM from the Registers drop-down box to display the MAXQ core registers' contents. Observe that relevant registers are updated as you step through the execution. Try the commands step into, step over, step out, and run to cursor to become familiar with the MAX-IDE.

Figure 6. The Statistics window lets you monitor machine cycles and execution time. Conclusion MAX-IDE, the MAXQ device simulator, can be used to develop and debug the MAXQ-based applications for the MAXQ10, MAXQ20, and MAXQ30 devices. The application developed with MAX-IDE is ready to run on the hardware. Appendix: Table of MAX-IDE Useful Commands Command Description File Menu New File... Open a new text/source file. Open File...
