MyRIO; USB6211 and Arduino

[Salman822]

I am trying to acquire data using Myrio, Ni-DAQ: USB6211 and Arduino in a single LabVIEW program under MyRIO project. (The data can be easily acquired when programmed in individual VI.) The data is received in MyRIO but we can acquire any data from USB6211. Also; there isn't any fluctuation in the load cell data being acquired from Arduino. (A zero line in the waveform graph is seen even when the load is applied).

Besides; is there any way to acquire or transfer loadcell data in MyRIO from HX711?

I've never used the HX711, but the documentation says it uses a single Data wire, and the Arduino example seems to open a serial port communication. Therefore, I would try to hook it up with something as UART in myRIO.

Additionally, remember myRIO uses LabVIEW Real-Time and FPGA, while the USB-6211 uses NI-DAQmx. Unfortunately, without seeing your code, there's little we can suggest about why your data is not fluctuating.

I also recommend checking the dedicated NI cards for strain measurements. I think they can make future projects easier to develop.

All the best,
