Example gyro code released.

No, not really. In the earlier code/readme.txt, I documented a way to integrate the bias over a longer period of time and then set the bias using Set_Gyro_Bias(). The latest code just automates this process. The real magic will come when I get a Kalman Filter integrated into the code.

Probably both. The new code, out-of-the-box, does a much better job of calculating the bias. Sampling at a higher frequency and down sampling with more samples also helps. I'd advise setting the sample rate to be as low as possible while still getting the performance you need.

Hi, I just wanted to let you know we implemented your code with the ADXRS300EB last weekend and it has been performing *perfectly* all week. Thanks for the excellent work . Now the camera is another story....

Cool!

Well, as Nietzsche said: That which does not kill us, makes us stronger <grin>.

Kevin,

Is this the same as the edubot guro code you have on your site?

Yes, there's a version with demo code for the EDU-RC and one for the FRC-RC. Both have a common source file that will make it fairly easy to use a gyro. By making the modifications to robot.c above, or waiting for me to update robot.c, you'll be able to drop this improved code into the scripting software.

Is there any reason why the edubot encoder code from your website won't work with the Hall effect sensors?
