    Reading a Digital Input

    hi all .. i am a newbee too .. i faced this digital input problem but have figured it now ... i do not have logicstart mega wing so i did not know the switch configuration until got the schematic of the logicstartmega wing ... this image will clarify the switch arrangement... hope newbies will find it useful .. another thing i read from papilio one that xilinx make Unused pins pulled down by default .. and i have calculated the internal pulled down resistor value which is 1825 ohms. so if any pin is made input it will have a internal resistor
