rwedler / as5x47

A library for Arduino boards that reads angles from AS5047 and AS5147 sensors. Also handles encoder configuration.

AS5X47 Library for Arduino

AS5X47 is a library for connecting AS5047 and AS5147 magnetic encoders to Arduino boards. It allows to easily read the angle measured from the sensor and also advanced features to reconfigure the encoder.

Hardware support

This library has been tested with the following encoders:

• AS5047P
• AS5047D
• AS5147P

Supported Features

• SPI Communication with encoders
• Abstraction of SPI Communication
• Read and Write operations for all registers
• Abstraction of angle measure
• Debug string to read the state of all registers at once
• One Time Programation (OTP) Abstraction

Please let me know if you tested it with other encoders.

Installation

Using the Arduino Library Manager (recommended): Use the Arduino Library Manager and search for AS5X47 library. Select the most recent version and click 'Install'. That's it, the library is installed!

Installing manually: For more information or manually install the library, please refer to the Arduino official page : https://www.arduino.cc/en/guide/libraries

Usage

Examples

Two examples are provided within the library :

• ReadAngle.ino shows how to connect the sensor and how to read the measured angle.
• ConfigureSensor.ino shows how to use advanced features of this library in order to manipulate the encoder registers according to the manufacturer datasheet.

Wiring

The encoder board must be connected to the SPI Pins of the Arduino Board. In the case of an Arduino Uno, connect as following:

For other boards, please refer to official Arduino page.
