Continuous Rotation Servo & Picaxe
October 29, 2008
Ok, so I finally got all my gear set up to build robot numero uno, but Im goin friggin nuts trying to control my continuous rotation servos from parallax. Im using a picaxe 18x to produce the code, but no matter what pulsout or servo commands I use, my servo's only go clockwise.I NEED them to be able to go counterclockwise for my differential drive train to work right. I have read every post on LMR about servos and have tried a lot. I have read their parallax data sheet and that they should respond based upon the pulse width, but no go. I have attempted calibrating with the potentiometer when set to the suppos'd center point at 15 mili seconds, but adjusting it NEVER reverses direction, rotating the potentiometer either way only changes my servo's speed.
code Ive used
and when trying to find the center, where the servo SHOULD stop Ive used ( I also adjusted the pot during every trial to see a change, but still, I only get them to change speed)
pulsout 4, (I've tried basically every value from 135 to 165)
any help would be much appreciated!
