    don’t think ???

    Not starting an argument here, but acceleration is measured in meters per second per second. Hence, you have to be moving to be accelerating. Gravity I don’t think can come into it.
    If I take my board and take the normally front facing LS20126 and face it downwards, I get a zero reading on the Z axis. I suppose I can just factor that out when using the board.
    Ummm…I’ve sworn on my dead brothers grave I’d not tell how Auto-calibration works (isn’t that the MOST stupidest thing ever), but if you feel comfortable with posting an email address you don’t use too often maybe I’ll let slip a few secrets.

    Did you actually get the acceleration feature to work (i.e. the string headed by “$PLSR,245,1” ? I was getting strings back such as this :-
    $PLSR,245,1,52,7,217,3,-12,235,31,0,1*1D
    Even after pestering Locosys (they wanted to know Company details and production runs….) I managed to get the device Auto-calibrated giving a ‘7’ as the second parameter (before it was 0, un-calibrated). But study the X,Y,and Z Acceleration fields. X is 3, Y -is -12, but Z is 235.
    With the unit at rest this is just strange.
    I’ve also noticed that this is more of a tilt unit. Hold the unit at a steady angle and these X and Y values remain at high values.
    Locosys now refuse to talk to me because I’m not a major player……soooo, has anyone else managed to solve this riddle ?
    Also, can anyone tell me how to decode the “$PLSR,245,2” returns ?
    I think this datasheet is quite severely flawed (probably through bad translation), although the Rep. said she was trying to protect their intellectual property rights. If a unit doesn’t do what it’s meant to do, I think a company has the obligation to everyone to help badly written documents.

No public wish lists :(
