Hi Dilip,

At the moment, we don't offer any drivers or libraries specifically for LabVIEW. It looks like LabVIEW offers basic serial read and write functionality, and so long as you can write bytes via RS232 you should have control over display.

National Instruments posted an example program demonstrating how to read and write to a serial COM port.

There basic read and write should help you get started.

In order to upload a font to the display, you will have to send the "Upload a Font File" command to the display. This command requires you to send Hexadecimal values '0xFE 0x24' to the display, followed by your font file data. This process is detailed in the GLK24064R-25-1U manual (found here: ... _178_32_36)

Unfortunately, we don't have a copy of LabVIEW here at the office, so I'm a little limited to what I can test here for you.

I understand you tried uploading fonts using MOGD#. In a different post, you said you were unable to detect your display through MOGD. Is this still true?
