I have a eddie robot platform and the encoder is Parallax Position Controller (#29319), but now my encoder is no work.
I use "Propeller Tool 1.3.2"(Eddie.spin) to send the command "Go 36 36" and "DIST","SPD",but result is all zero.

I try this method, but I don't know how to connect my encoder?

    Hello,

    If you are using the green position controllers, please be sure you are using version 1.1 of the Eddie firmware. You can download it here.

    Please also make sure that the jumpers on the left position controller is set to "1" (both jumpers installed) and the jumpers on the right position controller is set to "2" (A installed, B removed).

    We would also happily ship you updated quadrature encoders, if you would be interested in upgrading your Eddie robot.

    Cheers,
    Jessica

    I use     Propeller Tool v1.3.2( Eddie - ignore encoder errors ) to send command "go 36 36"and "dist", but the result is all error.

    Your connection method is correct, if it is connected as shown in the diagram. This is the recommended configuration from the documentation.

    Try typing 'verb 1', so that the error messages give you more details. With that information, we may have a better idea of the problem.

    Thank you for the information. The position controllers were very sensitive to reverse polarity and static, so they may have been damaged at some point.

    Please send me an email (juelmen@parallax.com) with your shipping address, and I'll make sure a new set of quadrature encoders get sent our to you ASAP.
