i am a senior biomedical Engineer ,

i am using labviwe in my project recently ,

i found it very interesting,although i dont khnow much about it.

i want to khnow how labview is useful at work?

since i think about spending time and start to learning it deeply,

See your previous post, and do not re-post the same question.

hi,Andres,

you are right ,

but i used From DDT & Index array functions between DAQ Assistant and get waveform attribute as you shown to me by picture,but still there is error ,

are these the same function you used?

also can i ask the Run is broken in the picture you sent to me ,dose it mean there is an error?

thanks for your reply,

Why not wire the waveform directly into the graph?

I suggest you look at some of http://wiki.lavag.org/LabVIEW_tutorial' rel='nofollow' target="_blank">these tutorials.

hi,yen

if i wire the waveform directly into the graph ,how i can control/change gain,frequency rate or port number if desired :question:

You should always explain a few things about your system: What version of LabVIEW are you using. Also, what data acquisition hardware. What operating system. It is also best show us what you have already tried to do yourself. You get better answers this way, and we like it when we can tell you are doing work yourself. I do not claim to know how much you have worked on this yourself, but it is common for people to ask us to do an entire project or assignment for them and this is not appropriate. There are many online resouces that you can investigate on your own.

The ingredients of your task (assuming I have interpreted you short desciption correctly) are as follows.

1) Find out the properties of the signal using a scope or similar.

2) Determine if this signal is appropriate for the data acquisition (DAQ) hardware, and if it is not, then construct the appropriate signal conditioning so the DAQ hardware can read the signal without damage and with an adequate signal to noise ratio.

3)Test the signal acquisition using the Measurement and Acquisition Explorer.

4)Acquire the signal into a numerical arrary of voltage readings.

5)Perform any post processing to this data that is needed: decimation, filtering and so on.

6)Save the data to a file appropriate for the internet receipient.

7)Email it to them, or send via ftp.

hi,mross

sorry about lack of information,

i am using labview 8.2,DAQ Assistant ,windows xp.

what i tried to do ,is using web publishing to send the waveform through internet ,and the waveform ,i want to transmitt is a nonperiodic signal(ECG,Electrocardigragh),

i implemented a circuit to take ECG signal from body ,then through DAQ card transfered to labview enviroment ,which suppose to let me to pass the measured ECG through the internet,but before doing this i wanted to be sure that i am in right track.

by Email is not prefared ,since we want the signal in real time transmission,that helpe the doctor or nurse to be intouch with patient in remote distance,

also i didnt understand what you mean by ftp??

i am looking for your further help please,

thank you for your help,

hi,

how to transmite a waveform which is generated by "hardware circuitry" to internet by using labview?

Here you go. This can most possibly be done better. But I think it would work.

i think i found what you mean,

thanks Anders Bjork,

hi,friends

how to connect a cluster of 3 elements as source and the sink of "1-d array double " not to get error

as shown below:

Seems like you need to do some unbundling, on the blue-with daq-data-line or re configure the DAQ-assistant so that it gives a double vector.

Anders Bjork,

can you show me by picture,please

thanks

hi everybody..

as i have shown in the picture ,an error occured while i connect the DAQ output(data)

to waveform input of "get waveform attribute",

i am confused to connect the data output of DAQ to cluster or to "get waveform attribute"??

(I removed all irrelevant info from your post)

Now what code do you have allready?

Ton

sorry,, i didn't understand,,, what do u mean by code??

please,hear me,

please answer me,

i have a problem in my project with labview 8.2 ,

which i affraid it will stop me till the submission deadline ,

How should i program a cluster for 3 variables,sampeling frequency ,gain mode,and channel port which become able to read a waveform from a port? :headbang:
