Hello maheswari...,

if you just need numerical output you will find some fonts here on the NI webpage addressing that issue. Just search the developer zone.

If you also need to display special icons form your LCD you can use picture rings containing an 'on' and 'off' state. Or you customize some boolean controls to show your icons...
Or you use a boolean array to simulate the LCD:


(So many possibilities!)

There are links to using the NI fonts and other examples as well that might fit your requirements.

the links were really useful.....i couldn open the block diagram of alphanumeric.vi.....in this only 20 characters are possible...but i need to create 30(as i am using 240x128)..but that vi has size 20 by default..so if i see the block diagram i could get some idea.....

and also,

i would like to know how they have used the clusters for the lcd screen...because the screen in the front panel is divided in to many clusters...

kindly clear my doubts....

If I understand correctly, the VI's only sorts out which elements in a cluster to switch on.

Potentially you can drill down the hierachy and extract the single character VI and then build your own displays. You can explore the cluster structure by changing it to a control and 'unbundling' the control.

To do this browse the hierachy and drag and drop one of the VI's (the bottom most) on to a clean VI diagram, then right click the output of the VI but tell it to create a control rather than an indicator. now you can unbundle it and see how it's built up.....
