Re: SONAR Sensor Software Driver

More specifically, to flesh out my teammates questions, we're using the vex sonar in our FRC robot, which has two pwm type plugs labeled INPUT and OUTPUT. We're not quite sure which locations these two wires should be plugged in at the controller, which the above sonar code is expecting.

emersont49: Are you talking about the ones that were on the old Polaroid cameras, or whatever developed from that? I don't think they are the same.

We have a couple of the Vex Ultrasonic Range Finder kits (http://www.vexlabs.com/vex-robotics-...nder-kit.shtml), which I believe are similar to the ones from Parallax.com (http://www.parallax.com/detail.asp?product_id=28015).

Qbranch: The sonar code's seem to be rather simple programming-wise, with help from the readme file. Call one routine to start the action, then call another routine to get the distance.

Our problem is where to plug the wires in. Or are we doing the code wrong? Or, like Tom Bottiglieri suggests (and I vaguely remember something of the sort, but hoping it wasn't true), it doesn't work with Kevin's PWM driver. There are too many unknowns, hardware and software, and it looks like we've got some grunt work ahead of us, and some hours with interrupts.

Too bad we can't plug the vex ultrasonic unit into the vex controller, then connect that to the FRC controller. Might be an easier path to take --- ?

I think there's been lots of activity since I last visited this thread, and suggestions. Thanks to all. And, not to beat a dead horse, but has anybody got *any* ultrasonic to work on FRC?
