(2.0) The Metalink Assembler
REV 1.3 -- 5 -- www.analog.com/microconverter
2.0 THE METALINK 8051 CROSS ASSEMBLER:
The Metalink 8051 Cross Assembler takes an assembly language source file created with a text
editor, 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)
as described in section 3.0.
2.1 Using the Metalink Assembler
1. In the C:\ADuC\ASM51 directory, double-click on the ASM51.exe executable.
2. In the DOS window that comes up, type the path of the assembly file you wish to assemble.
For example, to assemble the example file C:\ADuC\Download\DemoCode.asm, simply type
“C:\ADuC\Download\DemoCode.asm” as shown below.
The assembler will display the text “ASSEMBLY COMPLETE, 0 ERRORS FOUND”
indicating that it has successfully assembled the file and has created the hex and list files (i.e.
DemoCode.hex & DemoCode.lst) along side the assembly input file (i.e. DemoCode.asm). If
the assembler indicates assembly errors, you should view the list file (i.e. DemoCode.lst) to
examine the errors. To view the list file, open it with notepad or any standard text editor.
Note: If the assembler returns an error message indicating a failure to read drive A, 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 (where you clicked the ASM51.exe executable).
The ASM51.exe program can be copied/moved to another directory to prevent typing in
the long path name each time. 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, please refer to the ASM51 user
manual at C:\ADuC\ASM51\ASM51.pdf.

(3.0) The Windows Serial Downloader
REV 1.3 -- 6 -- www.analog.com/microconverter
3.0 THE ADUCWINDOWS SERIAL DOWNLOADER (WSD):
The Windows Serial Downloader (WSD) is a windows software program that allows a user to
serially download standard Intel Hex files as 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, setting of security bits and
various RUN options.
3.1 Opening the Windows Serial Downloader
1. Power up the evaluation board using the 9V power supply. Connect the evaluation board
header J4 to your PC’s 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…see
section 3.4 below.
2. The user should put the MicroConverter into serial download mode.
To enter serial download mode on the ADuC814 the user should:
Connect S3 into the DLOAD/DEBUG position and press the RESET button.
To enter serial download mode on any of the other ADuC8xx products the user should:
While holding down the “SERIAL DOWNLOAD” button press and release the
RESET button.
3. From the START menu choose Programs ADuC WSD. This launches the Windows
Serial Downloader application. The WSD executable 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 comms between the PC and the
evaluation board are setup correctly then the WSD should display the following text above
the top right corner of the Status Box.
'ADuC8XX version 2.Y
i.e. the screen shot for an ADuC841 below shows the result….

3.2 Downloading using the WSD
4. Click the Download Button. Select the file at C:\ADuC\Download\DemoCode.hex. Double
click on the selected file or click on ‘Open’ to download the file.
While the file is downloading a progress bar will appear indicating how much of the file has
been downloaded.
Once the file has been successfully downloaded the progress bar will disappear and the
Status Box will be updated with the message
DOWNLOADING CODE [C:\ADuC\Download\DEMOCODE.HEX]:..........OK
3.3 Running the Downloaded File
Running using the WSD
5. Click on the Run Button. The Status Box is updated with the message.
Run OK!
The program starts running from address 0000h, as can be seen by a flashing LED on the
Evaluation Board.
To perform additional downloads; repeat step 2 and press the RESET button on the WSD.
Manual Run Option.
6. Press 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 as can be seen by the flashing LED.
Note: DemoCode.hex blinks a LED on the eval board. The rate of blinking is reduced each time
the INT0 button is pressed
3.4 Additional Download/RUN Options
The MicroConverter incorporates a serial download protocol that also allows various
Download/RUN options (see uC004 at C:\ADuC\Documentation\TechNotes). These options can be
easily selected in the Configuration window as shown below (the Configuration button can be found
on the front panel of the WSD as shown in 3.1.3 previously). As you can see various Erase,
Download and RUN options exist here.

Certain options may be grayed out depending on the particular MicroConverter you may have.
Run Automatically after Download
7. Click on the Configuration button. Tick the box for 'Run automatically after download' as
shown in the configuration window above. Click on OK. Enter serial download mode as in
step 3.1.2. Download as in step 3.2.4. The program starts running automatically after
download as can be seen by the flashing LED.
NOTE: Use of the PC COM Port:
Only one application may use the PC serial port at any one time.
The WSD only uses the PC COM serial port when
•Resetting the device
•Downloading to the device
•Sending the Run command to the device
Therefore, the WSD does not have to be closed before launching the
Debugger/WASP/Hyperterminal or any other application that uses the PC COM serial port.
However if another application, that uses the PC serial port, is open then the WSD will not be
able to communicate with the MicroConverter until the PC serial port is released by
disconnecting/closing the other application.

3.5 Downloading via the USB-EA emulator
Chapter 4 will discuss using the USB-EA emulator for debug purposes. However, it is also possible
to use the USB-EA emulator to serially program the ADuC8xx parts via the EA pin – I.e., it doesn’t
require the a connection to the UART pins.
After you have installed the USB-EA emulator, your PC will assign the emulator a COM port.
When using the USB-EA emulator to download to the ADuC8xx, simply select this COM port in the
WSD application and proceed as per the earlier instructions.
For more details on the USB-EA emulator, see chapter 4.

REV 1.3 -- 10 -- www.analog.com/microconverter
(4.0) USB-EA EMULATOR FOR ADUC8XX DEBUGGING
The USB-EA emulator allows non-intrusive debugging of the ADuC8xx series of devices.
The USB-EA Pod is shipped as part of the Quick Start Plus kits or, it may be purchased separately.
The following parts are supported by the USB-EA emulator:
ADUC831
ADUC832
ADUC841
ADUC842/ADUC843
ADUC834
ADUC836
ADUC845
ADUC847
ADUC848
Note, the ADuC812/814/816/824 are not supported.
The debugger interfaces to the ADuC8xx via a single pin – the EA pin of the ADuC8xx part. To
enter debug mode, the part must first be placed into download mode by toggling the Reset pin while
holding the Serial download pin low. When using the evaluation boards, this involves keeping the
Serial download button pressed while toggling the reset button.
4.1 Connecting the USB-EA emulator to the target board
The pod connects to a PC via a standard mini-USB cable. It connects to a target board via a 2-pin
header. See the pictures below.
