Reem,

That's not a DAQ, it's a breakout board. I honestly think you're missing some high level knowledge. Is there anyone where you work that has programmed in LV that can help you? "Creating a Task" is plain LabVIEW talk. Read up on MAX (Measurement & Automation Explorer), DAQmx, and find your DAQ!

yes,,,i know i have alot to learn ahead of me but since i don't have enough time i asked the

question just to get a quick answer but seems that there isn't such thing !!

where i study ,they have all used old version of labview and seems they don't have enough information to help me...

Thanks for the advice ...

reem,

alzhrani's question was what type of physical card, in other words the DAQ itself. You've shown us a picture of the programming interface you are using, in this case an express VI.

There's no reason why you can't use Controls. I think you're missing something on a higher level.

i'm using this one: (if this is what u mean )

probably there is something (maybe a function)to use so i can control the signal from hardware but i'm using labview for like

3 month only and i don't know what exactly to look for?!!

creating a task and then writing chunks of the output as needed?? how??

can you show me an example if possible???

Thank you all for ur help...

What type of card did you have???

NI Daq assistant...are there different types of them??

btw Thanks for the reply...

Hi everyone...

a sinewave is generated -as shown in attached picture -that it's amplitude andfrequency is controlled using knobs. i did the same using DAQcard

and Tone measurementbut it mentioned that the numerics(knobs) i use must be as indicators and not control...

so,

how is it possible to control the amplitude, frequency of signal from DAQcard?? shouls i use any other function in between??

i'll be thankful for any suggestion and help

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

may i know what are the two functions u have used in between

"DAQ assistant" and "wave form Attribute"?? (namely)

Thnx.

hi ..

for the connection of cluster-bundle...do i have to input anything to bundle for sampling rate and gain mode selection?? (see picture )

if yes can u please let me know what to use??

(the bundle i have selected has there controls from cluster: gain/ sampling rate/ port.no from DAQ card)

is my question clear??

by the way..do i neee a seperate while loop for DAQ card??

Thanks,

You connected the cluster to the default value input of a primitive which retrieves a waveform attribute. If that's what you wanted to do, then you did it correctly (although you didn't give it a name or use a waveform).

If you want to build a waveform or get the data from it, there are other options in the waveform palette. You should really look at those tutorials and at the examples in the example finder (Help>>Find Examples).

yes, there is going to be a waveform connecteg to "get waveform" , this was just a small part of it...

thanks for the reply and help

Hi again,

when i use bundle for cluster, i take the output from the bundle itself??

( i mean that if i want to connect the cluster to a function such as "Get Waveform" how i do it??)

i have uploaded a picture of how i did it..is it ok??

Thanks,

Reem

If you monitor them one at a time (assuming different electrode placement) then a common EMG/ECG amplifier would work assuming you could adjust input filtering individually for each case.

aha,, thats the case then,,u have used diffrent filters for each case...

i would have liked to try that system

anyway...good luck with ur project Ceri...

QUOTE (shavec @ Apr 13 2008, 08:10 PM)

I currently have a system that is recording EMG signals from facial muscles which can also be used for recording ECG waveforms as im currently doing research.

Ceri

how is that possible?? since EMG is considered as noice for ECG measurement (and vise versa) , how can that system detect both ECG and EMG??

seems to be very intresting

QUOTE (tcplomp @ Apr 17 2008, 11:44 PM)

Google is your friend and the LabVIEW help is quite good. Search google for '3 hours LabVIEW' and '9 hours LabVIEW'.

Seems OK, I just can't see the datatype (float, integer).

The port number suggest you use the old(er) NI_DAQ device driver, is that correct? In that case you need a numeric, then right-click and select 'Data-Type->I32'.

Ton

Thanks for the help, 3 hour labview is a good source, i wish i had found it earlier..

i dont know how to assign data type to cluster..so as orko said maybe it would be better to look for some books!!

in my project, i have an ECG signal which taken from the patient using electrodes as sensor..the aim is to

transmit this ECG signal using labview to the internet... signal taken from the body goes to DAQ card and from there to lab view to be sampled ,

displayed and to be sent to the internet via "web publishing tool".

but about cluster part..i'm still not sure ..should i connect it as in this figure:

QUOTE (BrokenArrow @ Apr 17 2008, 11:56 PM)

i mean the port number of the DAQ card...but i'm not sure wheather i'm going to use VISA resource control..

Thanks 4 the tip

QUOTE (JDave @ Apr 17 2008, 10:57 PM)

I found it extremely helpful when starting with LV to read through the LV Beginners manual that a colleague had. If you don't have access to LV materials or training there are some books you can purchase as well.

David

Thanks for the useful information David,
i have a manual but it's just introduction to labview, and in UAE there isn't any book about labview..

i'm trying to do some practice, but since i'm used to pictures and figures ,
its difficult to start

now i have added numeric for Gain and Sampling rate to the cluster, have i used correct controls?? for the port No. i do the same??

and other thing is that, for other control blocks as shown in picture above for "Get Waveform Attribute" there is input /output ports, but
for cluster there isn't any ..even when i add controls to it , so how can i connect it to other control blocks??

QUOTE (crelf @ Apr 17 2008, 09:12 PM)

Ummm, I think he was suggesting that you should show us a picture of what you're trying to do.

if i knew what i'm trying to do i woudn't ask in the first place

i just know that i want to add gain (for.ex..mode 0) , sampling rate and port no. to cluster as input!!

and the rest i leave it with professionals ..

QUOTE (Doon @ Apr 17 2008, 07:34 PM)

Sampling rate, Port Number, and Gain all seem like standard controls that could be included in a cluster. I suspect you may be on the wrong path about what controls are. Maybe a little clarification (or a picture) would help.

8D

yes it would help , and i'll be thankful Doon...

or ur going to tell me "try it and see; if it doesn't work, Ctrl-Z" ?

QUOTE (TiT @ Apr 17 2008, 04:18 PM)

When you create a cluster it is indeed an "empty box", then just beside, create whatever controls you need (2 numerics, 1 boolean, 3 path, etc) and drag and drop these controls into the "empty box".

Hope this helps

Thanks for ur quick replay Antonie and Richard,

i tried what u said , but is numeric, boolian, path are the only ones i can drag and add to cluster?

if i want to adjust gain (for.ex..mode 0) , sampling rate and port no. from the cluster what should i add to that cluster??

hope my question is clear enough...

Hi everyone,

i'm working on a project with labview 8; i have to use cluster in it..

the problem is that it appears as an empty box ,how can i program the cluster??

(program cluster in such a way it accepts 2 or 3 variables)

thank you,
