AS1119 – Application Note
Software Manual
www.austriamicrosystems.com Revision 1.00 2 - 6
1. General Description
This document describes how to use the AS1119 Evaluation Suite Soft
ware in combination with the Demoboard.
The AS1119 Demoboard is available with 3 different LED-Matrix boards.
- 12x12 Matrix, white LED’s (default set-up)
- 8x18 Matrix, white LED’s
- 5x6 Matrix, RGB LED’s
2. Quickstart
Before starting the software make sure that the USB Po
wer supply and the USB box are connected to the
demoboard. After start-up the software is configured (per default) to work with the 12x12 Matrix.
On the first tab ‘Demonstration 12x12 Matrix’ there are one-click-demos. Just click the demonstration you want to
display and it will be shown on the 12x12 Matrix right away. To stop the demonstration, click the Stop Playback
button.
For one-click-demos on the 9x16 Matrix, go to the second tab. T
here some demonstrations for the 9x16 matrix
can be found.
To draw your one movie or frame to display go to the third tab ‘Drawing Tool’.

3. Editing and Creating new Demonstrations
In the tab ‘Drawing Tool’ individual frames and movi
es can be drawn and displayed on the AS1119.
3.1 Change LED Matrix
Every LED matrix needs an own *.xml - file. With the button ‘Load XML File’ the different config
uration files for the
LED matrixes can be loaded.
3.1.1 Structure of an *.xml - file
• chip i2cAddress: defines the address of the AS1119. 4 devices can be addressed (0x70, 0x72, 0x74 and
0x76);
• row
Pos and colPos: define the position of the matrix in the GUI;
• nrOfRow
s and nrOfColumns: define the size of the matrix;
• nrOfBlocksUsed: define if 2 or
3 matrix setting is used;
• LED row
and col: define the positions of the single LEDs in the matrix in the GUI;
• isRGB=
”1”: defines the LED as an RGB LED;
• hw
PosRed, hwPosGreen and hwPosBlue: is the hardware number of the LED according to the block
structure in the datasheet.
Example:
<ledConfig>
<chip i2cAddress="0x74" rowPos="0" colPos="0">
<matrix nrOfRows="9" nrOfColum
ns="8" nrOfBlocksUsed="2">
<led row="0" col="0" isRGB="1" hwPosRed="15" hwPosGreen="144" hwPosBlue="7"/>
<led row="1" col="0" isRGB="1" hwPosRed="14" hwPosGreen="144" hwPosBlue="6"/>
<led row="2" col="0" isRGB="1" hwPosRed="13" hwPosGreen="144" hwPosBlue="5"/>
<led row="3" col="0" isRGB="1" hwPosRed="12" hwPosGreen="144" hwPosBlue="4"/>
<led row="4" col="0" isRGB="1" hwPosRed="11" hwPosGreen="144" hwPosBlue="3"/>
<led row="5" col="0" isRGB="1" hwPosRed="10" hwPosGreen="144" hwPosBlue="2"/>
<led row="6" col="0" isRGB="1" hwPosRed="9" hwPosGreen="144" hwPosBlue="1"/>
<led row="7" col="0" isRGB="1" hwPosRed="8" hwPosGreen="144" hwPosBlue="0"/>
<led row="8" col="0" isRGB="1" hwPosRed="24" hwPosGreen="144" hwPosBlue="16"/>
<led row="0" col="1" isRGB="1" hwPosRed="31" hwPosGreen="144" hwPosBlue="23"/>
<led row="1" col="1" isRGB="1" hwPosRed="30" hwPosGreen="144" hwPosBlue="22"/>
<led row="2" col="1" isRGB="1" hwPosRed="29" hwPosGreen="144" hwPosBlue="21"/>
<led row="3" col="1" isRGB="1" hwPosRed="28" hwPosGreen="144" hwPosBlue="20"/>

3.2 Drawing of frames
After chosen the right configuration table, a matrix field is s
hown. With a left mouse click the according LED can
be put on and off again.
LED Matrix
With the buttons ‘Load’ and ‘Save’ single frames can be saved.
The Block Brightness sliders are setting the analog current for each block. For the 2 block setting slider A and B
are effective and for the 3 block setting all three sliders A, B and C are effective.
With the button ‘All LEDs On’ all available LEDs will be put on. This function can be use as LED test.
Paint Control
With load and save frames drawn framesets could be stored in *.txt files.
With export frames button the frameset
is stored as *.inc file which can be imported into a C-program.
With Load Frames also an *.gif can be imported into the GUI.
Playback
Here the “Playback Speed” of the displayed movie on the A
S1119 can be set. With slider to “1” the time between
the single frames is set to 32.5ms and with “15” the time is set to 487.5ms.
The “Number of Loops” define how often one movie will be repeated. This can be set from on time to endless.
Frame Control
- Cursor buttons: single frames can be selected
- Insert Frame: a single frame can be inserted into a movie
- Delete Frame: the displayed frame can be deleted
- Delete All Frames: all frames will be deleted
- Download Frame: the off line drawn frame or movie will be downloaded to the AS1119

Paint Properties
Single Color setting:
The Brightness of every single LED can be set in 256 ste
ps. The single LED also can be set to blink.
RGB setting:
With the color picker (blue box in the picture below) the col
or of the RGB-LED can be chosen. The three
channels of the RGB-LED can be set to blink seperatly.
Misc. Settings
- Enab
le Charge Pump (default: off): The charge pump can be turned on and off by hand
- Enab
le Direct Mode (default: off): The AS1119 will display the frame as soon as one LED is turned in
the GUI.
- Sync On (default: on): If two ore more AS1119 devices are used the needed to be synced. This will be
done automatically if the SW detects two devices in the *.xml file. The first device will be the master and
the other devices will be the slaves.
If the sync in deactivated, it can be shown that the devices are not running with the same clock.
- Load XML File: For every matrix an own *.xml file is needed.
- Init AS1119: With this button t
he AS1119 will be initialized and set to default status. When the USBbox
is connected via CON2 to the Hardware and if the RSTN pin of the AS1119 is connected to the pin 9 of
CON2 a hardware reset is applied before the init is done
- Reset AS1119:
Is only working when the RSTN pin of the AS1119 is connected to the USBbox.
