Demoboard Operation Manual
USB:
Connected/No connection. If the demoboard is correctly connected to the PC, the software should
find immediately the demo board.
Onboard / External:
Switch the actual AS5130 sensor from the on-board one (by default), to an external AS5130
connected on the "external AS5130 header" (see Figure 1).

SSI-Readout
After starting the demo software and selecting the "SSI-Readout" tab, the magnet angle, AGC value, PWM out
value are displayed (see Figure 4).
For a correct reading of the magnet angle, the airgap between the AS5130 top side and the magnet should be
chosen that the 0<AGC<63. If the AGC value reaches 63, the ALARM LED will blink to indicate that the
magnet is too far away from the sensor, and the measurement is not accurate or not valid.
Periodic Readout:
By unchecking this option, the angle and AGC values are not read anymore, and the displayed value
keep their last state during the normal readout.
The read period can be adjusted between 50ms and 1s (default 100ms), to have more or less
reactivity.
State:
Displays the state of the C2 pin on the selected AS5130. By default C2 = 0 (three wires mode).
The Lock indicator is the state of the lock bit in the serial stream. This bit should be always enabled.
Multiturn:
Counts the full turns of 360°
Traffic Lights (Diagnostic): (limits can be set)
Green: Gap between Magnet and Chip is OK
Yellow: Bigger Gap, but still OK
