Taking pulse output from DAQ

[Monireh]

Hi

I am working on 'wireless sum tracker module' project using LABVIEW; but I don't know how can I provide pusle to my circuit using LABVIEW.I was wondering if you can help me in this issue. please if possible tell me how can I connect my circuit to DAQ card to get pule.   

Looking foeward to hearing from you,

Sincerely,

Monireh V

Hello Monireh,

To give you the precise solution we would need more inputs from you.\

But considering some assumptions from my side If you are using the Desktop PC for the project and If you are thinking of the DAQ card then,

You can go with the mulit-function  DAQ cards which have pulse generation capabilities.

You will also get the Details about the connections from the corresponding DAQ card Data Sheet.

you can choose a specific DAQ card for your requirement from the above link. (I have assumed that you will be using PCI cards)

Hello,

Actually I need pulse from labview inorder to control a stepper motor.but I don't know how to achieve this goal.

I was wondeing if you can help me in this manner.

Hi Monireh,

try looking at the Signal Input output examples in the LabVIEW Example finder, they should help you figure out how to use LV to control your card.

Hi Monireh,

We need to know more about your control signal and experiment setup.  What hardware are you using?  Do you need hardware timed pulses? What do you need the frequency and pulse width of your signal to be?  You can take a look at the Example Finder to get started.  You can find the Example Finder at Help >> Find Examples in LabVIEW.  Once the Example Finder opens, double click Hardware Input and Output >> DAQmx >> Digital Generation >> Correlated Dig Write With Counter.vi.  This example should be a good starting spot for generating pulses.

i have a ready lab view program that should be connected to my hardware to provide it with pulses. In the program i should Connect the hardware to port0 line0, but i don't know where is it?

Hello Monireh,

You can find the pinout for your device from Measurement and Automation Explorer.  To do this, open Measurement and Automation Explorer at Start >> Programs >> National Instruments >> Measurement and Automation.  When this is open, expand Devices and Interfaces.  You should be able to  see your DAQ device.  Right click on your device and select Device Pinouts.  You are looking for a pin called P0.0 for Port 0, Line 0.

How can i generate 1Hz clock from labVIEW 8.2? 

[jschwartz]

Hi Monireh,

This completely depends on your hardware.  What hardware are you using? If you have a device with counters, you could use a counter output or correlated digital output.  You can find both these examples in the Example Finder.

Hello

Actually I wan to rotate a stepper motor by labview and then stop its rotation by labview when the voltage input to the labview becomes zero.

 I hope you can help me
