Software Usage
After starting the software the demo board displays several tabs described below.
Note: Before starting the software the board needs to be connected to the PC. For details read section 7.2.
3.3.1
2-Wire Readout
After starting the demo software by double-clicking the “AS5046.exe” icon and selecting the 2-Wire-Readout tab, position
information and analog output voltage of the rotary encoder is displayed along with other register information (see Figure 5).

Absolute angle information:
The absolute angle information is displayed in analog and digital form. It is calculated as:
degree = (360/4096*absolute position).
Absolute position information:
This indicator displays the absolute encoder position as a 12-bit value. Each digit corresponds to
(360 degrees / 4096) = 0.0879 degrees. The range of the serial absolute output is always 0 to 4095.
Analog output voltage:
The voltage meter shows the value outputted by Vout when the feedback and DACref is at default.
Magnetic range indicators:
Three lights indicate the magnetic input field of the encoder (Red, Yellow, Green)
