LPC11xx Simple blinky example

Detailed Description

Example description
The Blinky example is known as the "Hello, World!" of embedded programming. This example is a slight variation of the blinky theme in that the sysTick interrupt turns on the LED at 10Hz, while timer 1 turns off the LED at 11Hz. The LED on/off state should be slightly out of sync.

Special connection requirements
There are no special connection requirements for this example.
