I now need to use this I/O port to read a button i.e., when the button is pressed (sort of like Jeopardy buzzers) my program goes and takes data and locks out the button till it is ready for more data. I would naturally like to do this in TP 4+. Has anyone had any experience doing this? Any ideas on where to look? Thanks in advance, --Raj Chaudhury UCLA Solid State
