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 Micro-
Converter 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 for setting security bits and various run options.

2.
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 can be changed from COM1 via
the WSD configuration option.
Place the MicroConverter into serial download mode.

RESET switch.
3. From the Start menu, choose Programs > ADuC > WSD .
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 set up correctly, the WSD should display
ADuC8xx version 2.Y above the top right corner of
the Status box.
After 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 Downloader window, click Run .
The Status box is updated with the message
Run OK!
The program starts running from Address 0x0000; 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 Windows Serial Downloader window.
Manual Run Option
Press the RESET switch 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 the reset is complete and the LED flashes.
Note that running DEMOCODE.HEX causes an LED to blink
on the evaluation board. The rate of blinking is reduced each
time the INT0 switch is pressed.
