    Are you thinking of getting the voice to read you the tire pressure if it gets below a nominal value?

    "Right rear tire pressure is low. Car needs air badly!"
    What do you expect? Its a corvette

    I wouldn't do the tire pressure stuff, because you need special wheels, atleast on the SC430.

    Major bump...

    I have a smartire system and I need to do just this. It consists of the four transmitters on the wheels and a radio receiver that mounts inside. The nice thing is that the received has a remote display option that uses 10 pins. I believe this is some kind of serial RS-232 interface, however I can't confirm that just yet. It also has another 10 pin connection on the receiver that connects to something other than the remote display.

    If it is serial, software may be developed to read the thing with Labview. Anyone else interested in this?

    I wonder if it actually uses all 10 pins. I would think it's serial myself, but might be byte oriented.

    It may, as the 10th pin could be +12V for the remote display?

    I'm not sure. I might get at the thing with a scope and a couple buddies soon. We have it installed on a car for a university research project that I'm putting a CarPC in and we'd like to monitor all of our information in teh vehicle with our PC, including this.

    Edit: I now believe it is serial. I looked up the specs on one of the IC's inside the remote display and it is a serial transmitter utilizing RS-232 and RS-485 I believe. I have never heard of the 485 before, but I'll see what I can do about it.
