Within the limited realm of the supplied DLL, the only method I have been able to get button presses from the board to the computer is by polling the button state in a loop. This is OK for using toggle switches which are either on or off, but it’s been a real pain when trying to deal with momentary switches.
Is it possible to hook the buttons as an event? So instead of making the PC ask the button “are you on right now?” several hundred times a second, the button pokes an event to the PC saying “FYI, I was just pressed” which the PC can then act upon.
