LIFA+servo position control

[Chintha]

HI all, I have installed the Labview Interface for Arduino.

I just need VI s for the position control of servo motor

I have few questions regarding this
1) what is closed loop position control , can i do that with servo motor ( I am using RC servo -VS-2)
2)can i control my servo without using Arduino code , directly from m Labview
3)How to implement PID controller for position control of Servo

Thanx

can i control servo without using arduino code

[Chintha]

can any body send me the LabVIEW files for servo postion control

[Chintha]

plese tell me if i am in the wrong community ?

If you want to control servo directly from LabVIEW, you need NI Daq card.

Your starting point should be from this link : http://zone.ni.com/devzone/cda/tut/p/id/3367

Instead of Daq , can i use Arduino board ?

[Puneet_K]

Yes , you can use arduino board for controlling servo.

nobody is answering my question ,,,

1)can i some how know the current position of servo?

 2)once I know the position , using the  controller(PID) i want to get the desired postion more acurately?

This is my intention,, I have the Labview (LIFA ) files , but i dont know how to get my current positon of servo so that i can feedback the same to my controller?

Have you written any code for it, share with us.
