ST92163
DEMO BOARD
1 INTRODUCTION
The objective of this Demo Board is to provide the user with a hardware platform for rapid de-
velopment of an USB application with the ST92163 microcontroller. Starting from this
ST92163 Demo Board, the developer can add his own application by using the wrapping area
or with a daughter board connected via the 64 pin connector.
To help developers get familiar with USB applications, an example is provided and pro-
grammed in the ST92E163. After setting some jumpers, as described in chapter 3, the user
can plug the ST92163 Demo Board to the PC with the USB cable and dialogue with the ST
Demo Board software via different HID transfers.

2.2 FEATURES AND FUNCTIONS DESCRIPTION
2.2.1 RESET BUTTON
A reset button is provided for resetting the ST92163 microcontroller. The inverted reset signal
is available to the user via pin 30 of the I/O expansion connector.
2.2.2 RS232 CONNECTOR
The ST92163 Demo Board has one DB9 male connector and uses a standard RS232 cable
for communication between the ST92163 microcontroller and an external peripheral or a PC.
The following jumper configuration allows the developer to connect RS232 signals directly to
the ST92163 microcontroller . Note that all DB9 connector (P1) signals are available via the I/
O expansion connector (pins 1 to 7 and pin 34) and via the I/O connectors TP1 (pins 26 to 32)
and TP2 (pin 31).
Furthermore the ST92163 Demo Board allows the use of special peripherals (RS232 mouse
for example) by connecting the pin 7 of the DB9 connector to the VCC through a jumper (JP3).
Table 1. RS232 signal jumper configurations
2.2.3 I2C CONNECTOR
The ST92163 Demo Board has one connector (P2) for I2C communication.
The following table shows the correspondence between I2C connector pins and ST92163 mi-
crocontroller pins.
Table 2. I2C connector and ST92163 pin correspondence
2.2.4 TRIMMER
A trimmer (R8) let you exercise the Analog to Digital Converter. You only need to put a jumper
on JP8 to connect the ADC IN pin (P6.2) to the trimmer.
2.2.5 LEDS
Three LEDs can be directly driven from microcontroller Port 6. They can be used to test the
ST92163 I/Os. You only need to put jumpers on JP10, JP11 and JP12 to use the LEDs
jumper on RS232 signal

2.2.7 I/O EXPANSION CONNECTOR
On the I/O expander (J3) it is possible to connect a daughter board to develop specific appli-
cation. On this connector all the microcontroller’s pins are available but the developer will find
too the address latch outputs (pin 45 to 52), the RS232 DB9 connector pins (pin 1 to 7 and pin
34), VCC (pin 31 and 32) and GND (pin 33).

ST92163 DEMO BOARD CHARACTERISTICS
2.2.8 EXTERNAL MEMORIES
To offer you more flexibility , two external memories can be used directly with the ST92163
DEMO BOARD. To use the 32K of RAM or the 64K EPROM or FLASH ROM you just have to
put a jumper on the corresponding chip enable slot (JP2 for RAM and JP1 for EPROM/
FLASH).
The latch buffer (U4) is mandatory because the P0 port is multiplexed when you address ex-
ternal memory.
2.2.9 POWER SUPPLY CONNECTOR
The ST92163 Demo Board can be powered either through a jack allowing the use of an ex-
ternal AC/DC transformer or through the J2 connector allowing the power to be supplied from
an internal PC 5”1/4 power supply connector.
Note that by using jumper W1, you can choose to power your board from the VCC supplied by
on the on-board power supply (self power) or from the VCC supplied by the USB cable (bus
power).

ST92163 DEMO BOARD EXAMPLE
3 ST92163 DEMO BOARD EXAMPLE
3.1 INTRODUCTION
In this package, a user friendly example for the ST92163 Demo board is programmed in the
ST92E163 microcontroller. This example uses the ST92163 Demo Board as an Human Inter-
face Device (HID) that dialogues with the dedicated “ST Demo Board” PC software.
The ST Demo Board Interface, shown figure 3, allows to display the following information :
– Available USB HID Device : All HID devices connected to the PC are shown in this window.
– Device information : This information, obtained during the enumeration phase, refers to the
highlighted device in the “Available USB HID Device” window.
– Button State : This virtual red LED changes its state when the SW2 push-button of the
ST92163 Demo Board is pressed.
– Trimmer Value :This value is the re sult of the Analog to Digital Conversion of the R8
trimmer output.
Furthermore, the ST Demo Board Interface allows to control the LD2 LED by clicking the “LED
Control” virtual button and to change the PWM output value by moving the virtual slider bar.

3.2 INSTALLATION
The first step is to install the “ST Demo Board” software in your PC by using the setup.exe
command on the floppy disk provided with this package.
After that, put jumpers on the following connectors:
– W1: Put the jumper between “VCC” and “BUS POWER” to enable the power supplied
through the USB cable.
JP8: To connect the R8 trimmer to the ADCIN pin.
JP9: To connect the SW2 push-button to the P37 pin.
JP10: To command the LD2 led
. JP6 and JP7: To transmit TD and RD signals to the ST92E163 microcontroller.
To see the result of the “Slider bar” control, the PWM output pin (P53) has to be connected to
the connector of the LD4 LED.
Note: When you plug the ST92163 DEMO BOARD with the programmed ST92E163 for the
first time on your PC, “WINDOWS 98” requires some files. Insert your “WINDOWS 98” CD-
ROM to provide these new drivers and click on the CD-ROM drive as shown below.

3.3 HID TRANSFER
When you plug in the ST92163 Demo Board, you obtain the information that the host retrieved
after the device enumeration. It will be the VendorID, ProductID and Version Number (see
USB 1.1 specification or later). Additionally as string information is supported, you can see the
Manufacturer, Product and Serial Number displayed.
The Control Endpoint (endpoint 0) is used for the LED control and to change the PWM value.
An Interrupt Endpoint (endpoint 1), addressed each 20 ms, is used for the Trimmer Value and
for the Button state.
3.4 USING THE EXAMPLE
3.4.1 START
Launch the “ST Demo Board” software. Plug the ST92163 Demo Board to the PC USB con-
nector with the provided USB cable.
If the ST92163 Demo Board is plugged in for the first time see the note in chapter 3.2.
Afterthat, all the information concerning the device will be displayed in the “ST Demo Board”
window.
3.4.2 Button State
If you push the button SW2 on the ST92163 Demo Board, it will toggle the virtual LED called
Button State in the “ST Demo Board” window.
3.4.3 Trimmer Value
The trimmer (R8) position modification will transmit the new ADC value via the USB bus, and
display it on the progress bar.
3.4.4 LED Control
On “ST Demo Board” software window click the virtual button and it will switch on the green
led LD2 on the board. Clicking again will switch off.
3.4.5 PWM
The slider bar controls the brightness of the led LD4. Each slider bar value will be converted
to a pulse width modulation (PWM) from microcontroller.
