I want to send data through labVIEW to arduino using visa write and the process and take steps using arduino. After that I want arduino to send the necessary outputs via serial port to labVIEW which it should read using visa read and store it in a string. While I am able to individually write or read at a time, I am unable to do it consecutively. I have used advanced read and write vi for the verification of my code but to no avail. The error reads " timeout before execution". Please let me know where I may be going wrong. Also is there a way to write code for hx711 using labVIEW
