Hello I am looking at reading a voltage from an external source, and using that voltage to trigger an event if it is above some value or not. Is this possible to do with the serial port. I know some of the other posts on serial port things involve a stream coming into the serial port, but we don't have a stream. If the serial port is not possible to use, then might you have a suggestion of what I could use. Our options are USB, serial, PS/2, ethernet port, and firewire port. We are using LabVIEW 8.0 Thanks

I see a few people have downloaded it... Any thoughts?

We are working on a program at the moment that we want the video to loop on a certain time period. When an external action occurs, we want the video to continue recording the time left that we specified, and save the avi file. For the time being we are just using the stop button in place of the external action. However, when we hit stop the video doesn't stop recording and save till after the next cycle. This means that it will overwrite the recording that we wanted to save. Our program is below. Any help will be greatly appreciated, thanks. We have LabVIEW version 8.0 if that helps anyone.
