Arduino library for reading rotation angles from AK7451 magnetic non-contact sensor.

AK7451-Arduino-library

Arduino library for reading rotation angle from AK7451 sensor. This IC by Asahi Kasei Microdevices Corporation (AKM) uses a built-in Hall effect element to perform non-contact rotation angle measurements in combination with a diametrically magnetized two pole magnet. Communication is via SPI.

The sensor was tested using the Mikroe-2755 Angle 3 click breakout board with an Arduino Mirco and Arduino Uno as the sensor uses 5V. A diametrically magnetised ring magnet Ø 10/5 mm from supermagnete was used.

The pinout for the connections is as follows:

Arduino micro	AK7451/Angle 3 click
5V	5V
GND	GND
SCK	SCK
MI	SDO
MO	SDI
SS	CS

Currently only basic usage is implemented. This includes reading the absolute angle data, error and mode bits in Normal Mode (see the AK7451 datasheet for more details). User Mode is a work in progress.

Library installation in Arduino IDE is per the usual manner.
