There has been some confusion in the answers given. People talking about I2C and SPI are really referring about the accelerometer board, even though they might have slipped up and called it a gyro. The yaw rate sensor ("gyro") board provides a pair of analog outputs.

We have it connected to the analog breakout, but we're having problems getting a reading, so I'm not sure if that is due to a bad connection, or just a programming problem.
I don't know what you mean by "problems" here. What kind of reading do you get, and what are you expecting?

Do you see an appropriate battery voltage display on the Driver Station?

I definitely messed up and wrote gyro when I meant accel, another reason I shouldn't post at 4:30am.

Re: Gyro/Acceler. connections

I got it all wired up correctly, but I'm really confused on how to properly connect to it and recieve data from it in LabView. I've looked all over for the ADXL345 LabView example some other people have mentioned, but I cannot find it anywhere. It's not on the "Example" list in LabView, or in the FRC example code in the National Instruments folder, nor anywhere on the Classmate. I even did a file/folder search for "ADXL345" and it didn't return anything).

Did you install the mandatory LabVIEW update?

Re: Gyro/Acceler. connections

Ahh, that was the problem.

I installed the DS update but not the LabView one.

Re: Gyro/Acceler. connections

Also, can anyone tell me where the gyro connects to?
