QUOTE (BrokenArrow @ Apr 28 2008, 11:31 PM) 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 ...

QUOTE (BrokenArrow @ Apr 28 2008, 05:49 PM) 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?!! QUOTE (Tim_S @ Apr 28 2008, 06:35 PM) Without knowing what hardware you're using, I would suggest creating a task and then writing chunks of the output as needed. You would change the amplitude and frequency as you write out chunks, though I would recommend completing at least a half-cycle (waveform is a 0) to avoid discontinuities. Tim 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... Reem

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 Reem..

QUOTE (Anders Björk @ Apr 24 2008, 11:51 AM) 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,

QUOTE (Yen @ Apr 21 2008, 08:47 PM) 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 Download File:post-11300-1208783929.bmp

QUOTE (sachsm @ Apr 18 2008, 04:21 AM) 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) 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) 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) reem, For the port number, if you mean a serial port, you need the VISA resouce name control. But like has been said, if you're struggling with data types..... 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) 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) 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) 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) 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...
