Library of Infineon's highly sensitive [TLE5012B] 360° magnetic angle sensor(https://www.infineon.com/cms/en/product/sensor/magnetic-position-sensor/angle-sensor/tle5012b-e1000/) for Arduino.
The TLE5012B is a 360° angle sensor that detects the orientation of a magnetic field. This is achieved by measuring sine and cosine angle components with monolithic integrated Giant Magneto Resistance (iGMR) elements. These raw signals (sine and cosine) are digitally processed internally to calculate the angle orientation of the magnetic field (magnet). The TLE5012B is a pre-calibrated sensor. The calibration parameters are stored in laser fuses. At start-up the values of the fuses are written into flip-flops, where these values can be changed by the application-specific parameters. Further precision of the angle measurement over a wide temperature range and a long lifetime can be improved by enabling an optional internal autocalibration algorithm. Data communications are accomplished with a bi-directional Synchronous Serial Communication (SSC) that is SPI-compatible. The sensor configuration is stored in registers, which are accessible by the SSC interface. Additionally four other interfaces are available with the TLE5012B: Pulse-Width-Modulation (PWM) Protocol, Short-PWM-Code (SPC) Protocol, Hall Switch Mode (HSM) and Incremental Interface (IIF). These interfaces can be used in parallel with SSC or alone. Pre-configured sensor derivates with different interface settings are available.

Please find the datasheet of the TLE5012B here. It depends on the evaluation board which you are using or the respective configuration of the sensor on your PCB which communication protocol as well as addresses you need to use for communicating with the sensor. This library only works with the SPI compatible Synchronous Serial Communication (SSC) interface of the TLE5012B.
