On the LabVIEW side, use the VISA Write to send your data. On the Arduino side, use the Serial.readStringUntil() function to read the data. I recommend concatenating an End Of Line to the end of the string and use the Line Feed (0xA) as the "until" on the Arduino. This can be reversed by using the opposite instructions.
Its an FPGA board and atmega16U2 is used to configure the FPGA and provide USB interface between FPGA and PC.
This board has micro usb connector which is connected with USB port of atmega16U2 and I know the maximum data rate is 12Mbps.
There is adept 2 software which can send and receive data using micro usb and its SDK is also available on github.
Does anyone know how to receive data in LABview?
