LABVIEW – Tip #34 – Serial (VISA) – Arduino (button) to LabVIEW

Level : Intermediate

A communication with an external device can be done via USB-Serial-VISA. In this example, the arduino sends the letter ‘A’ by the serial port when the button is pressed and the letter ‘a’ when it is released. Meanwhile labVIEW is waiting for communication through a production cycle, which has the ability to recover if a serial port for disconnected. The consumer cycle makes a change in the control value.
