I have a data acquisition card (Matrox Solios) which uses an input trigger signal to trigger a connected camera. This card is connected into the computer through a PCIe port. The device came with a collection of C functions; however, none of them can actually output the trigger waveform that is coming into the card.
For troubleshooting reasons I want to see that the signal the card is getting is the trigger signal we are sending it. My adviser believes that this information (although digitized) is accessible through the PCIe port. Suppose that this information is actually being outputted into the computer. How do I access this information?
