Re: LMD18201

I tested the PWM outputs on the robot controler... I have the MINI RC with me, with 8 PWM outs each programmed from 0 - 255. Then I brought out my RC servos, 3 wires and plugged it into the Mini RC PWM outs. They responded accordingly, setting the servo arms at various locations. Since servos use RC PWMs to determine positions, wouldnt the PWM on the robot controller work as well?

On the data sheet, it says that a 50% duty cycle is zero or neutral, that would be 1.5ms pulse. I do believe our Robot controllers work within the 1 - 2ms pulse width correct?

This page contains a nice picture showing the RC PWM and the regular PWM (right side of method 3), could someone tell me which PWM type is in our robot controllers? The blue one or the red one?
