ADuC8xx Evaluation Kit Getting Started User Guide

INTRODUCTION

This user guide functions as a tutorial to introduce the various tools that are part of the MicroConverter® QuickStart™ development system. Because these tools are ADuC8xx generic, this user guide applies to all ADuC8xx parts.

The ADuC8xx parts and the evaluation boards referenced in this tutorial guide are shown in Table 1. The tools described in this user guide are listed in Table 2.

Function

This assembler takes an assembly language source file created with a text editor and saved with a

.asm extension, and translates it into two files: a listing file output (.lst) and a machine language object file in standard Intel HEX format (.hex).

The WDS is a Windows® software program developed by Analog Devices, Inc., that allows one to serially download standard Intel HEX files created by the ASM51 assembler to the MicroConverter while in circuit.

Keil and IAR provide a complete IDE integrating all tools necessary to edit, assemble, simulate, and debug assembly source code via the serial port. Download the latest 8051 tools from the official Keil-An ARM Company or IAR Systems Software, Inc. company website(s).

WASP is an analysis tool allowing easy measurement of the analog noise performance of the MicroConverter.

This emulation is used for nonintrusive debugging using Keil or IAR development tools. It is also used for serial downloading via the EA pin and the WSD software.

INSTALLATION

INSTALLING FROM THE CD

1.Insert the MicroConverter QuickStart Development System CD-ROM into your CD ROM drive, select the CD-ROM drive, and double-click on the setup.exe file.

2.Follow the screen instructions to install the software on your PC.

UG-041

Note the following regarding installation:

•Although you can install the software onto any hard drive and into any directory, the remainder of this user guide assumes that you have installed the software at the default location of C:\ADuC.

•If you already have a previous ADuC8xx QuickStart Development System tool suite installed on your machine, this version may also be installed by default at C:\ADuC. The ADuC8xx software tools installation automatically updates any previous ADuC8xx tools in this directory.

THE METALINK 8051 CROSS ASSEMBLER

The Metalink 8051 Cross Assembler takes an assembly language source file created with a text editor and saved with a .asm extension, and creates two files: an output list file (.lst) and a machine language object file in standard Intel HEX format (.hex).

The list file output (.lst) displays the results of the assembler operation, including any syntax or other errors present in the original source code.

The Intel HEX file (.hex) is used to program the part using the Windows serial downloader (WSD).

USING THE METALINK ASSEMBLER

1.In the C:\ADuC\ASM51 directory, double-click on the ASM51.exe executable.

2.In the DOS window, enter the path of the assembly file you want to assemble. For example, to assemble the example file C:\ADuC\Download\DemoCode.asm, enter

C:\ADuC\ Download\DemoCode.asm.

08412-002

Figure 2. DOS Window

The assembler displays ASSEMBLY COMPLETE, 0 ERRORS FOUND indicating assembly of the file and creation of the hex and list files (that is, DemoCode.hex and DemoCode.lst) with the assembly input file (that is, DemoCode.asm). If the assembler indicates assembly errors, view the list file (DemoCode.lst) to examine the errors. To view the list file, open it with Microsoft® Notepad or any standard text editor.

If the assembler returns an error message indicating a failure to read the A drive or a fatal error opening a file on the A drive, then it is most likely failing to find the MOD52 or MOD8xx file referenced by the assembly file. Make sure all MOD files (plus any other “include” files referenced in your assembly code) are located in the C:\ADuC\ASM51 directory.

The ASM51.exe program can be copied/moved to another directory to prevent typing in the long path name repeatedly. Make sure that the relevant MOD files are also moved with the ASM51.exe program.

For additional details on the use of the Metalink ASM51 assembler, refer to the ASM51 user manual at C:\ADuC\ASM51\ASM51.pdf. This manual was provided on the evaluation kit CD.

THE ADuC WINDOWS SERIAL DOWNLOADER

The Windows serial downloader (WSD) is a Windows software program that allows a user to serially download standard Intel HEX files created by the ASM51 assembler to the MicroConverter via the serial port. The standard Intel HEX file is downloaded into the on-chip Flash/EE program memory via

a selected PC serial port (COM1 to COM32). The WSD also incorporates the protocols for downloading to Flash/EE data memory, and setting security bits and various run options.

OPENING THE WINDOWS SERIAL DOWNLOADER

1.Power up the evaluation board using the 9 V power supply. Connect the evaluation board header, J4, to your PC COM1 serial port using the RS-232 dongle cable provided. The PC serial COM port may be changed from COM1 via the WSD configuration option.

2.Place the MicroConverter into serial download mode.

•To enter serial download mode on the ADuC814: Connect S3 into the DLOAD/DEBUG position and press Reset.

•To enter serial download mode on any of the other ADuC8xx products:

Hold down the Serial Download button, and press and release the Reset button.

3.From the Start menu, choose ProgramsÆADuCÆWSD. This launches the Windows serial downloader application. The WSD executable, provided on the CD, is located at C:\ADuC\Download\WSD.exe.

The WSD automatically sends the reset command to the MicroConverter. If the MicroConverter is in serial download mode and the communications between the PC and the evaluation board are setup correctly, then the WSD should display ADuC8xx version 2.Y above the top right corner of the status box.

DOWNLOADING USING THE WSD

From the Windows serial download window

1.Click Download.

2.Select the file at C:\ADuC\Download\DemoCode.hex.

3.Double-click on the selected file or click Open to download the file.

Figure 4. Open Window

While the file is downloading, a progress bar appears indicating how much of the file has been downloaded.

Once the file has been successfully downloaded, the progress bar disappears and the status box is updated with the message

DOWNLOADING CODE [C:\ADuC\Download\DEMOCODE.HEX]:.. OK

RUNNING THE DOWNLOADED FILE

Running Using the WSD

From the Windows serial download window, click Run. The status box is updated with the message

Run OK!

The program starts running from Address 0000h; this is indicated by a flashing LED on the evaluation board.

To perform additional downloads, repeat Step 2 in the Opening the Windows Serial Downloader section and click Reset on the WSD.

Manual Run Option

Click Reset on the evaluation board with the Serial Download switch released (for the ADuC814, switch S3 to the Normal position). The program starts running automatically after reset and the LED flashes.

Note that DemoCode.hex causes an LED to blink on the eval board. The rate of blinking is reduced each time the Int0 button is pressed.
