Re: Encoder issues

The other confusing thing is that the E4P encoders from US Digital have two different three-digit sections in the part number. One of them is usually 250, meaning its code disk is meant to press on a quarter-inch shaft. It's the other section that you need to be looking at to decide whether it's a 250 or 360 count per revolution disk.

I don't know if it's only the code disk that determines the resolution, or if the circuit base differs as well. I think we'll have a chance to find that out, as our practice robot seems to have ended up with 360-count encoders on the drivetrain while our competition 'bot has 250-count ones. We have a couple extra 250-count code disks that can be substituted (if we can get to that part of the robot without taking too much apart).
