AS5030 8-bit Programmable Magnetic Rotary Encoder
Adapterboard Operation Manual
5.3
Jumper configuration: P1 and P2 close.
The command line and data line are separated:
The command line is a MCU output connected to DI, the
data line is an input of the MCU connected to DIO.
With this configuration, synchronous blocks like SPI can
be easily used to receive the 16 bit data value from the
AS5030. This communication method simplifies the
firmware code as well.

Jumper configuration: P1 and P2 close.
The Daisy Chain mode allows connection of more than
one AS5030 to the same MCU.
Independent of the number of connected devices, the
interface to the controller remains the same with only
three signals: CSn, CLK and DO.
In Daisy Chain mode, the data from the second and
subsequent devices is appended to the data of the first
device.
See AS5030 datasheet chapter 4.21.
