The controller can be connected to the demoboard via the I/O Connector “D”. If no controller is available the austriamicrosystems USB box in combination with the AS1115 White Goods Demoboard software can be used as well. This USB box is needed to set-up the connection between the demoboard and the USB interface of a PC. The USB box can be ordered via http://www.austriamicrosystems.com. The AS1115 Demoboard is controlled via the software and the board is only working in connection with software. The condition of the LED’s (ON or OFF) or the different buttons can be triggered via the software or directly on the board. Picture 1: Software Panel Note: As a first step make sure that the hardware connection between the PC and the Demoboard via the austriamicrosystems USB box is set. The second step is to connect the software to the board. For this go to the USB menu and click on “connect” (see Picture 2: Software Panel detail). If the USB sign on the right lower side (see Picture 1: Software Panel) is turned to green the software is correct linked to the demoboard.

If not present get the datasheet for the AS1115 from www.austriamicrosystems.com. Use the IC on the demoboard only with the recommended settings and values as described in the datasheet. 2. First connect the Power Supply (+2.7V to +5.5V) to the demoboard (VDD “A” and GND “B”) and than power up the controller (I/O Interface “D”). To power down the system disconnect first the controller and than the Power Supply of the demoboard. 3. For the data format of the I²C interface please see the datasheet of the AS1115. Have fun using the demoboard. If there are questions do not hesitate to contact us. See contact information at the end of the application note. www.austriamicrosystems.com Revision 1.04 5-7 AS1115 - Demo Board Manual White Goods Layout of the demoboard Board schematics and layout Figure 3: Schematics Figure 4: Top view www.austriamicrosystems.com Revision 1.04 6-7 AS1115 - Demo Board Manual White Goods Copyright Copyright © 1997-2009, austriamicrosystems AG, Schloss Premstaetten, 8141 Unterpremstaetten, AustriaEurope.
