Comparing X to target X?

[ciruap]

Ok, I am using a touchscreen to produce x-y coordinates.

I have two stepper motors mounted on a chassis below the screen that can tilt the x and y coordinates.

Example:

The ball is located at the position 0,0 on the screen

I entered the target position on the motion controller as 10,10(center of screen).

What steps are required to compare the two x coordinates and the two y coordinates in order to send the correct signal to the motor?

Hi ciruap,

Thanks for your post.

To help you out as best as possible could you please provide a bit more information about what you are trying to achieve? Are you using LabVIEW to compare these coordinates? How is the coordinates from the touchscreen going to be formatted into your program? How is the touchscreen connected? Similarly how are your motors connected up, and what hardware are you using?

If you have started to program in LabVIEW would you be able to post your VI?
