[jimboli]

Hello my friends!

i´m tryng to interface with labview from an home made board.

It used to rum very well but now (one year later)it does not.

wen i run the programme ,it show´s me an error!!

error code:-1073807202 occurred at property node in VISA Configure serial Port(INstr).vi->pic 16f877A Read.vi

This error code is undefined.No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input. 

Can Any one hellp me??

One possbile cause for the error : The error means that you don't have VISA installed. It's on the device drivers CD.

But since you told for 1 year it worked fine, just try a quick search in the forum. Go through this link

I dont think without visa it would have run for an year. check your com port number? If you have changed it. Try reinstalling visa.

Maybe jimboli means that his application/hardware used to work, but he hasn't used it for one year, and now he has tried to run it again.

Jimboli, in the meantime, maybe you changed something in your PC? 

As suggested by Mathank & Muks, re-installing VISA (and checking the port number) should solve the problem.
