Printing & Using The Pwm Value ? ?

Question

Good Morning EZ-Scripters ! Attached is my crude attempt to use and display the PWM Value. :Start # PWM(D19,50) # :Loop # $x=GetServo(D19) # #WaitForChange($x) # Print($x) # Goto(Loop) # PWM(D19,50) initializes to 50%, and the Slide Bar changes its value, but my Print Value does not change ? Thank You All & Best Wishes, DougPope@cox.net, 602-246-1246(H) RoombaSpeedControlUsingEZ-B'sPWM1-Feb-2013.EZB

When you set port D19 to PWM, it is not a servo, it is PWM.

PWM = Pulse Width Modulation SERVO = A device used to provide control of a desired operation through the use of feedback

Every control has ? next to the X (close). If you press the ?, you will be directed to a tutorial page for that control. I suggest viewing the PWM control tutorial and watching the video. It explains a little of what PWM is. PWM will not work with the Roomba. The roomba speed is controlled by SetSpeed() and GetSpeed().

The EZ-Script manual is next to the editor.

Good Morning DJ ! Thank You for both your Tutoring and your Patience with the aged. Your PWM Video is GREAT ! Cleaver how you used a Single Ribbon Cable from multiple EZ-B Ports to the H-Bridge. It's now on to GetSpeed() & SetSpeed() ! SetSpeed( speed ) Sets the global Movement Speed value Example: SetSpeed(50) GetSpeed( ) Returns the global Movement Speed value Example: GetSpeed() Thanks Again, DougPope@cox.net, 602-246-1246(H)

Anytime Doug! It means a lot to me when I see someone find the solution with a little guidance - rather than doing all the work. Kudos!
