Evaluation Board Gyro

How exactly would you hook up the normal gyro and how impossible is it?

You can use the gyro with code created by Kevin Watson, available at http://kevin.org/frc. Readme files included in his code instruct you on what needs to be done to get the gyro working, and it is pretty much as easy as following those directions to be able to use it (though it will probably take a good 30 minutes or hour to get the gyro working if you've never done it before).

As for what you can use the gyro for, that's left up to your team's imagination.

And is there any difference between the programming for the normal gyro and the EB gyro?

programming wise if you use the AnalogDevices gyro it will be the same. I believe Kevin Watson's code is set to use both the 150 deg/sec and the 300 deg/sec gyro, if that is what you are using. If using EasyC I think you need to scale the output by a certain factor to get the correct output. It depends on which model you are using.

From our experience, if using Kevin's code, you'll probably also want to narrow the gyro deadband if you're using a 300 deg/sec gyro (else it won't see small rotations).

we used the gyro ordered from FIRST and wired just the 3 twist holes to pwms, but we get the same random reading if the gyro is attached or not. im assuming this is a soldering issue. but what else could it be? do you need to wire the Temp (R)?

You don't need to wire them up to the Temp.

It's probably a soldering issue.

i hooked up the gyro to an oscilloscope and it worked fine there. and the soldering looks ok too. what exactly would we be looking for when the gyro is connected to the RC with WPI?
