Maybe someone have used it and is it working simple as 4 outputs with logical 1 or 0 value?

Hi,

I don't have one, but it looks absolutely trivial to use. The outputs of the compass are "open-collector", so you'll need to use a pull-up resistor on each output (10K would be fine), or enable the internal pull-ups if your hardware supports that option. then, simply use the INPUT statement, and some simple logic to determine the 8 possible heading directions (N, NE, E, etc.).

Cheers,

Nigel
