I m new, learning the lab view i have created a lab view program of digital storage oscilloscope. i want to give input to that dso program. for that i have converted the analog signal to digital and also convert it into serial by using 89c51 microcontroller.how to give it to that dso program?? my media of communication is RS232.
You will need to provide further details, as what you have said is sketchy, at best. What do you mean by "give input to that dso program""? What is this dso program? Is this your LabVIEW code? If so, what's the code do?
If I understand correctly, you would like to read the serial data from your microcontroller into a LabVIEW program. With NI-VISA you can perform serial communication. A good example is "Basic Serial Write and Read," found in LabVIEW under Help » Find Examples » Hardware Input and Output » Serial.
