JM Accelerometer v1.0 XYZ silkscreen and specification at odds #743

Closed tballmsft closed 3 years ago

tballmsft commented 3 years ago

See spec and image below. They disagree when the module is on the bottom edge (as given by the X-axis), the spec says that Y = 1, but acceleration is in Y is in the negative direction. All other cases are correct. Shouldn't the specification have -1 for all cases?

Gentlemen, please decide what the behavior will be for the current accelerometer/silkscreen.

tballmsft commented 3 years ago

@jamesadevine, @pelikhan ping - we need a decision here.

jamesadevine commented 3 years ago

I think it should be oriented with respect to gravity. It's a bit more intuitive to understand.

OK. please make the change and I'll test and update the doc.
