How to output strings on an LCD

[Abook7]

I have a project and I want to use labview to display some strings as output on an LCD. Can anyone tell me how to use an LCD? or how to enter data to it and how we connect it?

Thank you

Kind of importamt to specify the type of lcd you are using. Look at the interface. Some sort of digital input is typical. An NI digital IO board could be used. Do a search based on how many pins you need to control.

Actually i didnt choose what type of LCD,im new here and im still learning, I just need a simple LCD to out for me a string for example : "the weight of this object is 3 kg."

If you don't have one already you probably should get one with a serial interface. I think most of them use TTL (0-5V) signals. You can use your PC's serial port to talk to these if you build or buy a level converter. Sparkfun has some and they probably have a level converter.

If you go that route then look for the serial communications examples that ship with LabVIEW.

So I understand from what you're saying that using an LCD would take a lot of time to configure and build a special circuit for  it  and to connect it to labview?

Using a serial one will be easier. The level converter is pretty easy and you can find one at Sparkfun or examples of how to do it. But easy is relative. You will have to read the datasheet for the lcd to figure out how to set it up logically and electrically.

Not with a serial LCD.  You may find one that is 232 compatible.  This would only require you send the appropriate commands and strings to the device.  If you go the parallel route, more work would be involved.

I've been using the SLCD5+ for exactly what you want to do.
