The easiest way to install this library is to use the build in Arduino Library Manager. Just search for AS5047P an install the latest version available. You can also upgrade the library to the newest release via the Arduino Library Manager. For detailed information please read the section Using the Library Manager of this tutorial. (Pleas keep in mind you need at least version 1.6.2 of the Arduino IDE in order to use the Arduino Library Manager)
You can download the latest version of this library here as a zip file and follow the section Importing a .zip Library or Manual installation of this tutorial about How to Install a Library.
You can find this library here in the PlattformIO Library Manager. To add this library to your plattformIO project you can either use the library manager ui and search for this library or you can use the following platform io cli command: pio lib install "jonas-merkle/AS5047P"
