Using "In port.vi" and "out_port.vi" in Windows XP

[Meyerss]

I have old demo board that only has a parallel port connection for reading and writing data. I saw that using the Parallel port in Windows XP can be tricky. I currently have Labview 7.1 and was wondering if I need to download and install AccessHW? Also could I use VISA in this circumstance, where I need to both write data to the demo board (to control the microprocessor), and then read the data back that the microprocessor collects. Any direction as to what resourse are available would be great.

Thanks,

Scott

Scott,

AccessHW.zip should work for WinXP according to what I have read..(though it may vary with SP1 or 2 or updated drivers etc.) If it does work for you...that would be the easiest way to communicate via your port in XP.

Brett,

I was able to do even better then that because I found that labview already had a few examples which used the "in port" and "out port" functions.
Thanks, for the help.
