Printing & Using The Pwm Value ? ?

Good Morning EZ-Scripters !

Attached is my crude attempt to use and display the PWM Value.


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,

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,

:) 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!
