Re: Encoders vs. Hall Effect vs. Banner Sensors
Our solution may be a little bit of overkill, but it worked very well.

We used 64 pulse Bourn Optical Ecoders geared about 6:1 to the wheel speed. We wired these into a custome circuit box that had 2 COTS chips. I can get the technical details if anyone wants them. I'm a mechanical guy so I don't know myself. I do know that the first chip took the quadrature signals and turned them into one pulsetrain at 4 times the frequency and a digital signal for forward or reverse. The 4 times frequency pulsetrain was then sent into another chip that was an digital to analog converter. We read the analog output from that chip into the RC as wheel speed. No interupts required.
