Description
Hitting this button during microcontroller (µC) operation will show up the menu. If the menu is already shown this
button will cycle through the menu options. If the demoboard is controlled externally this button has no function.
Menu mode: This button will cycle reverse through the possible values of a menu option.
Normal mode: A button press will activate the onboard uC.

Circuit
Figure 2: Circuit
Starting Up
Mounted Chip
The demo board is designed to work with the
AS1100,
the
AS1106
and the
AS1107.
Per default an
AS1107 is mounted on the demo board. If another IC must be tested, please remove the AA cell “A”
from the board and disconnect the external power supply if connected.
The AS1107 can now be removed and exchanged with the AS1106 or AS1100.
Power Supply
Figure 3: Mounted Chip
The demo board is powered via a single AA cell “A” or through the external power connectors “C”. An AS1320 will
boost the input voltage to the required voltage. The maximum input voltage must not exceed 3.5V DC.
If the demoboard is battery powered please make sure a fully charged rechargeable battery or a new disposable
battery is in use. The
AS1320
will convert even low voltages of nearly run out batteries very efficient, but if a worn-out
battery is used the intensity of the LEDs might be reduced.
For a maximum of intensity the external power connection should be used.
Figure 4: AS1320
External Interface
The demoboard can be controlled via the onboard microcontroller or through an external device. This
can be done with a standard 3-wire interface. Additionally there is a pin for the readback of data as well
as a ground pin, if such is required for the data line. Multiple demoboards can be cascaded if the
DOUT is connected to the DIN of the next board.
Figure 5: External interface
The two soldered
AS1751
are used to switch data either from the external interface or the onboard microcontroller to the mounted
AS1100, AS1106 or AS1107.

Menu
If the demoboard is used with the onboard microcontroller a menu can be called up pressing the MENU button “D”. There are three menu
points available:
Option
Description
This menu option regulates the intensity in 16 steps.
This menu option allows setting the speed in 5 steps.
There are 3 different programs to choose from:
Program 1:
Shows: “ AS1100 AS1106 AS1107 “
Program 2:
Shows BCD characters: “0123456789-EHLP”
Program 3:
A test pattern cycling through all possible variants of characters.

If not present get the datasheet for the AS1100, the AS1106 or the AS1107 from
www.austriamicrosystems.com.
Drive the IC
on the demoboard only with the recommended settings and values as described in the datasheet.
Place an AA cell in the battery holder or connect an external 1.5 to 3.5V power supply. The input voltage will be boosted via the
soldered
AS1320.
Activate the board using switch “B”.
The board will power up and can be used now. For information how to interface with the chip through the external interface
please see the
datasheet of AS1106, AS1107
or the
datasheet of the AS1100.
Have fun using the demoboard. If there are questions do not hesitate to contact us. See contact information below.
