Graphic LCD display
The LCD display shows the real-time absolute angle position of the magnet as a digital word (0…360), as well as the
current sine and cosine value of the output voltage.
Turning the knob clockwise will increase the angle value until 359, then 0.

EXT LED
The EXT LED indicates whether the internal (on board) AS5115 or an external device is used and which values are

Installing the GUI on the PC
The preliminary software is developed for a Microsoft Windows XP operating system with Service Pack 2. In addition
the dotnet (.NET) framework version 2.0 or more must be installed on the PC. This package can be downloaded free of
charge from the Microsoft webpage:

Following Procedure is recommended before starting the GUI:
1.
check on your PC if Service Pack 2 is installed
2.
install the mentioned .NET package to your computer
3.
execute setup.exe
4.
Finally start the GUI using the shortcut in the start menu or desktop.

The Home tab
Figure 3 shows the main window of the GUI. On the top left corner, board information as firmware (FW) version and
demoboard name declaration can be found.
By default the GUI is in the auto detection mode. Any connected austriamicrosystems demoboard and programming tool will
be automatically detected and displayed in the right top corner. The GUI is divided into three main sections HOME, TWI and
OTP.
By selecting the TWI (AS5115 bidirectional serial protocol) tab, the information of the angular position appears. See figure 4.
