I am developing some C# code for a keypad to use with the FEZ Dimino . All seems to be going as expected but i having a little problem with how slow it is taking from the time i push a button until i get the interrupt to handle the event. I have to push the button for about 2 seconds before i get the interrupt.The glitch filter time is 20ms. If I continually hold the button down i get an interrupt about every 2 seconds. Does anyone have an ideas on how to speed this process up?
