EMG in labview

[Srinithi22]

How do I obtain the EMG data in Labview (what is the block diagram code) without the use of DAQ ?

Thanks.

What is EMG? What hardware do you have? DAQ just stands for Data AcQuisition, and it sounds like at some point you are going to need to acquire data!

It typically helps to spell out acronyms because they can mean many different things to different people. I assume you are talking about this.

LabVIEW does not care what the data represent, so the process does not need to know the type of data.

Where does the "data" come from?

• If you want to read existing EMG data from some file, you need to know how it is formatted
• If you have an EMG instrument and you would like to control it or get data from it with LabVIEW, you need to read the documentation.. How is it connected (serial, ethernet, GPIB, etc.)
• If you want to acquire EMG data directly using LabVIEW, you need some DAQ hardware and drivers. Typically some AD converter and signal conditioning appropriate for the type of raw signals.

Please provide more information on what problem you are trying to solve. Thanks!

We have the Electromyography (EMG) hardware (Opal Kelly) which has electrodes that is connected to the subject. We are connecting the Opal Kelly (FPGA module) to Computer through serial port. We need to acquire the real time emg data from the subject and feed it and display in labview but without using DAQ devices. Please share your valuable information on this.

Thanks.

I have no experience with this hardware, but their API mentions LabVIEW. So maybe start there.

This company also has a forum and there are some threads mention LabVIEW. Maybe you want to ask there.
