I am designing password based door lock system using LPC 1769. I have build up the code of changing the state but now I am stuck to use joystick pins or switch key 3 or switch key 4 pins to use as an external interrupt. This I am using to reset the system whenever i give an external interrupt. Please help me to configured any switch key to use as an external interrupt and please tell about external interrupt service handler framework in general.
