Help needed:Real time generation of data

[bharath_reddy]

Hi all,
I am new to this group and labview also.My problem is that i have
to generate a continuous waveform for real time purposes from a text
file i have.I can read that but how it is possible to continuously
generate the data as a signal.

Can anybody know this
please share your ideas with me.It is quite urgent for me!.
I am adding the VI file and the data as text file.The VI file can read
my data (text file)and produce the waveform.All i have to do is make
it continuous and have to generate using the DAQ output.
If you have the code please let me know.

Thank you very much

can you please attache your files?

I am attaching the VIs of reading the text data and the data input.
           
                                    Can we generate this in continuously as a DAQ output.and also iam refering the example from labview e\xample finder"Cont Gen Voltage Wfm-Int Cll-On-Board Regeneration".Can the integration of these two possible.?? i.e,the continuous generation of this data in analog ouput?
Thanks,
Bharath

Hi mike ,
         It seems to be working.
         I have one basic doubt.What is that constant '1' that is given to attribute 'dt'.
         Is it that numeric constant or control or something other?If,yes it is not giving continuous output.
         Can you please tell me in which palette i will get that???
Thanks,
Bharath

Hi Bharath,

dt is the time between the y values in seconds. What do you mean with continuous output. You can create the waveform and connect it to, for example a DAQmx block. The card will then generate the connected signal.

Yes sir i know about 'dt', but i am not able to give a constant '1' as you given in your VI.
My doubt is where (in which palette) can i get the constant .
Is it the numeric control or constant??I tried those!!
Can you tell,though it is basic.
Thanks,
Bharath

ok thanks mathan.
I will try that.
