How can I program a Vex Ultrasonic Range Finder (sensor) in LabVIEW??
I think it would be easier to use a different ultrasonic sensor. You could open it as an analog input and use the analog in VIs to pull values from it.
Start with the Ultrasonic example in LabVIEW. The Vex sensor is nearly identical to an SRF04 ultrasonic rangefinder. The wiring and programming is the same. (There might be different timing; I do not know for sure.)
