I have seen in the past, some code for
reading the ADXLxxx Accelerometer. Does
anyone know where I can find some code
on that subject.

Thanks

    www.analog.com/iMEMS/products/ADXL202.html has links to tech notes and
    articles, including Stamp code.

    Try www.analog.com/techsupt/application_notes/ADXL202ped.pdf for one
    specific example, and a shorter app-note at
    www.analog.com/techsupt/application_notes/StampXL202.pdf. Also take a look

    Anyone know where I can get an inexpensive carrier board for the
    ADXL202? Or is everyone soldering wires to them? Supplier? Part
    number? etc.?

    Thanks,

    The best way to experiment with the ADXL202 accelerometer is to purchase the
    evaluation board. The samples currently available are the ADXL202JE which
    is a 5mm x 5mm x 2mm 8-lead hermetic LCC package. No leads! VERY tough to
    solder wires to and VERY tiny. Unless you have an 8-lead LCC chip carrier
    or you custom build a board and reflow the solder (yes, you can buy the
    solder paste and reflow in a toaster oven)... it's best to stick with the
    evaluation board. The part number for the evaluation board is ADXL202EB.

    More information regarding the ADXL202EB can be found here:

    [font=arial,helvetica]yes, only with the BS2p. With some programming work you may be able to do
    this with a serial LCD and a BS2.
