SS490 ratiometric hall effect sensors calibration

A quick demonstration of the calibration procedure of a SS490 ratiometric hall effect position sensor. It shows how to limit the range of the readings of the sensor on the AMC1.6 board (same applies to AMC644USB)

The SS490 ratiometric hall effect sensors are a nice contactless solution for position feedback that needs only two magnets to read accurately angles of 0 to 180 degrees. This can replace potentiometers that are normally not designed for too much motion because of the friction and have generally limited life cycle.
