Code for two stepper bricks does not work. Can anybody help?

[Harry88]

Following is a VB code for 2 stepper bricklets.  The hardware works with the example shown on the Tinkerforge homepage.  Can anybody tell me why this my code does not work and what I have to change? The 3 error messages from Visual Basic are shown at the end of the code.

 

The code is for a two axis measuring tool to move the table.

 

Thank you!

 

Best,

Harry

OUTLINE

​Module MeasureReed

Reset device position​

WaitForStart() 

For x = 35 to 71 by 1

  ​For y = -9 to 9 by 1

​​MoveDeviceTo(x,y)

​    ​MeasureReed()

        ​Output measurement

​Next y

​​Move Excel cursor back up and to right

Next x

Did you try what I explained in your German version of this thread?
