The AS5600 is an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog or PWM output. This contactless system measures the absolute angle of a diametric magnetized on-axis magnet. This AS5600 is designed for contactless potentiometer applications and its robust design eliminates the influence of any homogenous external stray magnetic fields.The industry-standard I²C interface supports simple user programming of non-volatile parameters without requiring a dedicated programmer.By default the output represents a range from 0 to 360 degrees.It is also possible to define a smaller range to the output by programming a zero angle (start position) and a maximum angle (stop position).The AS5600 is also equipped with a smart low power mode feature to automatically reduce the power consumption.An input pin (DIR) selects the polarity of the output with regard to rotation direction. If DIR is connected to ground, the output value increases with clockwise rotation. If DIR is connected to VDD, the output value increases with counterclockwise rotation.
LibDriver AS5600 is the AS5600 full function driver launched by LibDriver.It provides magnetic angle reading and other functions. LibDriver is MISRA compliant.

Reference /interface IIC platform independent template and finish your platform IIC driver.
Add the /src directory, the interface driver for your platform, and your own drivers to your project, if you want to use the default example drivers, add the /example directory to your project.
You can refer to the examples in the /example directory to complete your own driver. If you want to use the default programming examples, here's how to use them.
