SERIAL COMMUNICATION USING VISA

My project is regarding Room Light Intensity Control using Labview, in which my hardware is ready and working fine. The only problem I am facing is how to transmit my input signal from labview serially to the microcontroller PIC16F877A, via MAX232. I tried using the example given by NI with Labview, for Basic Serial Write and Read, but there is an error Hex 0xBFFF009E displayed when I run the program. So, if some body can please help me out of it would be great. Thank you.

Hi

 

That error is related with your Installation of VISA. You need to reintall VISA. What version of VISA do you have and what is the version of your LabVIEW? Here is a link of the VISA version that you need acoording with your LabVIEW version.
