Re: Encoder Problems

You can test the encoders using the PSOC I.O. board. If you remove the plastic head from the PWM cables the pine can be connected directly to the PSOC pins as follows.
Orange = VDDIO
Blue = P6_0
Brown = Ground
Yellow = P6_2

Configure the pins as inputs floating. Start the driver station and turn the motor on or spin the encoder by hand. The values should display on the drives station lower right corner.

To install the encoders you should use tools from US Digital or make your own.
The tools ensure that the encoder is centered correctly around the shaft and set the disk to sensor distance. The centering tool is just a small alum collar that fist over the shaft and into the hole of the encoder PCB. The disk insertion tool is a flat plastic disk that presses the disk in slightlt farther than tha cover tabs (approx .05 in farther). The side of the disk that looks like the surface of a CD goes toward the sensor PCB.
