Re: Help the field crew, reset your gyro in autonomous

We're considering adding a gyro for backup heading. We were thinking of putting in an LED to let us know when the calibration is complete, but we weren't sure if there's anything in LabVIEW that tells us when it's complete (i.e. how do we know when to turn on the LED?). The signal light on the robot won't start flashing until after Begin.vi is finishes, so I'm thinking that once the signal light starts flashing, the gyro calibration is complete. We'll have to test that out at the school.

As a backup, I'm considering doing it the old fashioned way - just reading the analog voltage and doing our own bias and integration.
