A counterclockwise pulse changes the state of a second output pin.
These signals could then be connected to any two of the RC's digital inputs 3-6, and the interrupt on change capability of the RC can utilized as desired. Our robot doesn't use gear tooth sensors, but if a team or two going to Atlanta would like to play around with one of these, then let me know and I'll bring a couple. All you would need to connect them up to an existing GTS is a couple additional PWM cables. A little bench testing with a GTS seems to indicate that it works fine, but I have not tried it on an actual robot.

Hi Mike,
I was thinking about making something like that to use with our gear tooth sensors.
Do you just have the chip, or do you have a protoboard as well? We'd definetly be interested in using them on our robot. We are using 2 IFI gear tooth sensors on our drive.
