serial data transfer to Arduino

[dheek]

Hello,

I want to send letters serially to the arduino board to make our eye controlled wheelchair turn in specified direction.

We have written a program in arduino IDE where we have specified one letter for each direction( W= move front, A= move left, D= move right, h= halt).

when we detect our eye is in the left side, i want to move my wheelchair to the left. If its on the right, i need to send a letter 'D' to make it move right. how do i send a particular letter to the arduino board. We have an arduino toolkit installed for labview  2012.

could you please help me out.

Hey dheek,

You won't need to use the LIFA toolkit for this.  You can use NI-VISA to open the serial port and write data (using a string in LabVIEW).  Check out the example finder in LabVIEW  (Help>>Find Example) and search for Serial or VISA.  There should be some basic examples to get you started.

Let us know if you have more questions.

Thanks!
