Automatic/periodic set of sensor magnetization and offset measurement …
↓↓↓ Complete description, time index and links below ↓↓↓

In the last video we generated magnetic fields, covered the interrupt handling and inhibited measurements on axes (link below). So far we’ve covered all but 5 bits of the status and control registers. Let’s talk about those 5 remaining bits now.

These bits control the automatic and periodic set of the sensors’ magnetization. The datasheet is a bit sparse on the details, so we’ll have to experiment a little. Since I had a little time left, we’ll also measure the AMR Wheatstone bridge offset.

00:00 Intro – implementing remaining configuration settings
00:39 Automatic/periodic set – of the sensors’ magnetization
16:35 Wheatstone bridge offset – measured using set and reset
26:44 Wrap-up – next up is temperature compensation, bye
