Program which demonstrates the usage of the IOCONFIG & GPIO peripherals. Program only blinks the LED based on the push of the button embedded on the LPC4088 QSB. Blinking is done using the primitive delay function which only makes microprocessor busy for some time. Source code is split - we keep register definitions in header files away from the main source file.
