1.2 Introduction
This section describes the connection and startup of the USB08
(universal serial bus) evaluation board demo application. The main
component of the USB08 is the Motorola MC68HC908JB8 8-bit
microcontroller (MCU).
1.3 Required System Configuration
To connect the USB08, you will n eed a personal co mputer (PC) with one
of the following Microsoft® operating systems:
• Windows® 98
• Windows ME
• Windows 2000 Professional
NOTE: Ensure that the PC has the necessary hardware (universal seri al bus
(USB) host control ler and USB roo t hub) and th at the necessar y system
drivers are installed.
Microsoft and Windows are registered tr ademarks of Micr osoft Corporation in the United States
and/or other countries.

1.4 Connecting the Demo Board to the PC
Since low-speed USB devices should be equipped with a captive
connection, the USB cable is fixed on the USB08 board (downstream
direction). In the upstream direction (PC/host side), the USB
connections are always type A. Therefore, t he cable of the USB08 demo
board has a type A plug.
The connectio n of the d emo board i s made directly to the USB socket of
the PC or, as shown in the Figure 1-1, to a USB hub.
Figure 1-1. Demo Board Connected to the USB Hub
The board supply current can be delivered by the USB connection.
Therefore, the jumper JP2, which is directly beside the USB cable, has
to be in the position Bus Powered. The jumper JP1-A (jumper block,
highest position) must be opened, which corresponds to the default
shipping configuration.

the Windows 2000 oper ating system. The installation using Windows 98
(second edition) looks quite similar.
After the electrical connection of the demo board, the Windows
operating system recognizes the presence of a new hardware
component and shows the message Found N ew Hardware.

1.6 Starting the Windows Demo Application
The windows demo application:
• Shows the measur ed val u es and push butto n infor matio n com ing
from the demo board
• Allows the controlling of the demo board light-emitting diodes
(LED)
The demo application is located in the root directory of the USB08
product CD. The file name of the demo application is IO08USB.EXE.
This program can be started directly from the CD.

As shown in Figure 1-7, the bottom line of the applicat ion window sho ws
the status of the con nection establi shed to the US B08 demo boa rd. The
LED symbols on the left upper side of the application window can be
switched on or off by pressing the keys of the USB08 demo board.

Starting the Windows Demo Application
By setting the check boxes on the upper right side it is possible to switch
on or of f the LEDs o f the demo board. The needle pointer instruments on
the lower side of the appli cation window in dicate the measur ed values o f
the three variable resistors:
• Input 1 represents the photo sensor.
• Input 2 shows the thermistor value.
• Input 3 can be varied using the turnable regulator.
The USB08 evaluation board can be disconnected from the USB port
and reconnected at any time, because the drivers are automatically
activated or deactivated by the Windows operating system. The
activation/deactivation of the drivers can be watched in the operating
system’s device manager window (start button/settings/control panel/
system/device manager) . The catalog entry USBIO c ontrolled devices
and the device entry USB08 Evaluation Board are visible only if the
hardware is present. See Figure 1-8.

The Windows demo application, IO08USB.EXE, must be re-started in
the case of a hardware connection interrupt. This is because an
automatic resynchronization (though it would be possible) was not
implemented here. The demo application is arranged as simply and as
understandable as possible.

2.4 Circuit Description
A schematic of the USB08 de mo boa rd i s provide d in Appendix D. Bill
of Materials and Schematic. The MC68HC908JB8 MCU needs few
external elements. A wide range of peripheral functions including the
USB module and an 8-Kbyte FLASH memory are integrated on-chip.
The MC68HC908JB8 is offered in several packages. For the USB08
reference design, the 28-pin SOIC version was chosen instead of the
20-pin dual in- line packa ge (DIP) becau se the SOIC p ackage has som e
additional I/O pins.
