Dear Kkronline,
 
What do you mean by interface with your LCD? When I think of the PCI-6014, I think about analog inputs/outputs, digital IO, and counter operations. Which of these measurements do you want to use with the LCD? General Charater might even have a description of how you connect its LCD up to a DAQ board. Have a great weekend!
 
Sincerely,

Dear Karthikraja,
 
I didn't find any examples of how to interface with your PCI-6014 using ASCII, but take a look at Write Dig Port to see how to write data to your digital lines.
 
C:\Program Files\National Instruments\NI-DAQ\Examples\DAQmx ANSI C\Digital\Generate Values\Write Dig Port
 
Since your the DIO lines on the PCI-6014 are static, you will have to do software timing and output your data in a loop. Have a great day!

Hello all,

Finally i did myself to solve the LCD interfacing with DIO lines. Herewith i am enclosing the VI's for our friends. LV send the ASCHII values via digital io lines.

I used the Dynalog DAS card for Controlling the LCD. u can replace with NI APIs.

 

thanx for the support

Karthik

You are responding to an old thread and as the op mentioned, Dynalog hardware is being used so of course the functions for that hardware would be missing. As the op mentioned, you would need to replace them with NI functions for your hardware.
