Creating a drop down menu configured with VISA write

[priyadamico]

Hi I'm using the Basic Serial Write Read example vi in LabVIEW to communicate using the serial port. Instead of having a write box on the front panel connected to the VISA Write in the program I want to create a drop down menu on the front panel to be able to choose from a variety of commands. Is there a way I can program multiple commands into the block diagram and choose one of them on the front panel to send to VISA Write? For example, the commands to choose current are I/E\s0\r for 1 A, I/E\s-1\r for 100 mA and so on. I want to be able to choose between 1A, 100mA, etc on the front panel and have the code send the corresponding function to VISA Write. Is this possible?

where do you list the values and the codes?

Usually you right-click the control and select "Edit Items."  this pulls up the item editor.

However, this editor is limited because it only enables "Normal" display for strings.  So just wire array constants to the "Strings and Values[]" Property like so:

To place a combo box on your front panel, 1. Right click on the front panel ==> go in the string & path menu ==> and select combo bo

2. Then Right click on the combo box and select edit items...

3. untick Values match Items

4. Edit your values.

 

I advise you to make a type Def with your combo box. It will be easier to add elements if you need.
