I need a PC I/O card that has an ActiveX or standard dll interface that will provide a change on I/O event. The I/O card will receive 8 inputs and generate an event if the state of any of the I/O points change. Pulling data requires to much of the CPU, so I would like the board to generate a software event. I have talked to a couple manufacturers of data aquisition equipement and none of them gave me a sensable solution.
