Quick Gyro Questions
 

In terms of wiring a gyro...
G is Ground on an Analog Input
5 is the +5V on an Analog Input
T is the Signal on an Analog Input

Correct?

And the Gyro received in this year's kit is the AD22304, correct?

Thanks.

in the KOP gyro thi year, above the holes there are letters. just plug the male end of a pwm cable into the appropriate holed (by colour and the writing on the board)

You are correct.

tseres:
They will be too loose and give you inaccurate results by simply plugging them in. You will need to solder the connections.

We prototyped the Gyro tonight and had some success with it.

Definitely solder the connections to the Gyro board, and mount the gyro to a hefty piece of metal so that it is parallel to the horizontal plane.

We used Kevin Watson's 2006 default gyro code to test it. The readings in tenths of a degree were pretty accurate when rotating the device.

The gyro velocity angle is still a little confusing to us. I'm not sure it provides useful information.

Keep in mind that all readings are based on the intitial gyro bias calculation at startup. If the gyro is abruptly disturbed after this calculation, all readings may be corrupted and will be suspect.

Temperature can also introduce drift in the readings.

We have more work to be done. However , it will probably only be used for Hybrid-mode anyway.

I have a question, there are two slots for plugging in pwm cables into the gyro but the easyc code has it set for 1 analog slot, so do I use a y-cable to plug both in, do I create a new gyro block for the second one, or do I only use one of the slots (if so is it G5T or G5R)

The set of pins with the signal pin labeled T is the gyro signal, which changes based on the rotation of the gyro chip. The other set of pins is a built in temperature sensor, since the gyro signal output changes based on the temperature. Under FRC conditions, you won't really need to use it.
