Re: Evaluation Board Gyro

It should work if you just wire the twist pins, but go ahead and do the temp pins two. Perhaps the board wants power at both. You don't have to do anything (program wise) with the data. Then make sure your program is accessing the correct analog port for the twist signal.

Just to clarify a couple of things:
The KOP gyro is an ADXRS150. It is already on a small PCB with the necessary components to make it work. I see no reason you would want to use an ADXRS150EB in place of the KOP board.
If you are going to buy additional gyros, get the EB version.
The software interface to the both gyros is exactly the same - it's the same chip.

Re: Clarification

Thank you very much, StevenB. :)

Re: Evaluation Board Gyro

So I wired up both the rotation and twist pins (all 6), and I'm still not getting any output. This is on the KOP gyro, btw. Any suggestions?

ah, fixed it. Slight wiring issue (I blame it on the freshman that did a lousy job soldering : P).

Re: Evaluation Board Gyro

Hi

Team 1629 requested the KOP GYRO by email, but all we got was a set of Target Light lamps.

I swear I saw an email/blast or something about what to do if the gyro didn't turn up, but I've searched and can't locate it.

Has everyone else received their Gyro?

EDIT: I tried the obvious of re-emailing FIRST, but the sensor address is bouncing

Phil.

Re: Evaluation Board Gyro

We got ours with our light, so yes you should e-mail them.

I know it's an answer in the Q & A, I'll try to find it later today and post it up here.

In response to question #2, additional sensors to those provided in the kit are permitted. However, sensors not provided with the Kit of Parts should be evaluated using <R47> and <R48> and installed per <R72>.

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).

Re: Evaluation Board Gyro

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.

Re: Evaluation Board Gyro

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?
