Accelerometer Help!

Does the accelerometer have to be connected to specific pins on the analog breakout (i.e. AI1 - AI8)? Is there a specific test we could perform to check whether it's operating correctly? We tried using the oscillator but the data we were getting weren't exactly helpful.

Re: Accelerometer Help!

There's no specific port for it, just don't use AI8 on module 1, since that's for battery voltage.

The easiest test is to turn it vertical and note the change in reading. If you lay the board flat, you should get the steady state center reading. By standing it up, you are putting one of the two axes in line with acceleration due to gravity. Measuring in this position should give a reading of the steady state plus or minus (depending on the orientation) the V/g sensitivity of the accelerometer.

Re: Accelerometer Help!

How would you be able to read what values the accelerometers and sensors are outputting?

Re: Accelerometer Help!

To read the values of the accelerometer, just run accelerometer example code on the LabVIEW library. With the example code you should be able to read the inputs of the accelerometer.(just make sure you use the right port for it )

you can find this example under(if you have labview)
c:\Program Files\National Instruments\LabVIEW 8.5\Examples\FRC\Accelerometer

Yayness! Thanks for your help
