Hi,

I really need to use all of my 4 vex sonar sensors in my bot, but it seems that microcontroller interrupt ports 3,4,5, and 6 do not work with the sonar sensors. I've tried new batteries, updating the firmware, swapping out one sensor for another, I've even tried a second VEX controller and STILL have the same problem.

Is this a bug? A feature?

Is there a work-around?

Or am I just stuck?
