how to get digital signl into labVIEW

[yh87]

hi,i have 1 problem that is how to get digital signal into LabVIEW without using DAQ card

Hello,

There are many ways you could load a digital waveform from file:

The Read From Measurement File Express VI

or

The Read Wavefrom from File VI

or 

The Simulate Arbitrary Signal Express VI- use the Define Signal > Load Data button.

If this doesn't help, could you provide more data, also why can you not use a DAQ card?

i will try the solution given

Hello,

The above suggestions may not help, if they don't, please give further detail into what you are trying to do.

Thanks

i need to do 1 programme using labVIEW the output is an EPOS control robot and the input is EMG wave but i also not sure how to get EMG wave into computer and our group choose not to use DAQ card because it istoo expensive

Not sure if it's the same thing but there is a driver for a Maxon EPOS motion controller.

If you need to acquire an external signal and if by EMG you mean electromyogram, you are either going to have to purchase a DAQ device or design and build one yourself.An EMG is not even close to a digital signal.
