How can we send a sine signal from LabVIEW to Arduino using VISA Write?
We are trying to generate a sine signal from labview and send it to an arduino uno microcontroller through a usb cable so that we can monitor a sine wave in an oscilloscope but we haven't figured out...

Dear All. We use the attached "write_complex_binary.m" funtion in matlab to write complex numbers into a binary file. The format used is the IEEE floating point with big-endian byte ordering. And use...

First you have to serialize the waveform data so it can pass though the serial connection. Then you will need to write code that runs on the arduino the converts the serial data into whatever form it...

Actually you don't need the loop. If you want to simply concatenate all the elements in a string array, all you need a one string concatenator. Pass in an array of strings and you will get a string out...

Your snippet works just fine for me. PS: You don't need the SGL bullet in the upper picture. Just wire a constant to the type input of the conversion and set its representation to single float. Also...

Re: Single Precision Float (SGL) not working as per IEEE754
I agree with the others that you need to clean up your code, because it is just way too convoluted. Your "bytes Input" should probably be U8.To demostrate the concept, you don't even use formatted...
