Figure 2:
Mechanical Configuration
The magnet should be aligned by reading the output of the AGC register of the AS5601. For optimal
alignment, the AGC value is in the middle of the AGC range.
Note: If the magnetic field seen by the AS5601 is below 8mT, the output is disconnected and
permanent angle programming is not possible. The AB output will not show any change until the
magnet is present again.
5.1 Electrical Setup
The Adapterboard can be used in 5V or in 3.3V mode in the configurations shown below. Short J1
to operate in 3.3V mode.
5.1.1 I
2
C Mode
Using the I2C Interface, all functions of the AS5601 can be configured and permanently
programmed. Additionally the output and a raw angle (unmodified value) can be read from the
output registers.
