I'm looking at the AS5311 magnetic field position sensor.
The IC presents a couple ways of getting the absolute position of the magnet in relation to the sensor. You can either read out a 12-bit value from the serial port, or use the 244Hz PWM output.
The datasheet says that you should average/filter the values to obtain an accurate result. Does using the PWM output make this easier or something?
In what situations would I want to use the PWM output instead of the simple digital interface?
