Robbie King / DMX

This is a fork for okini3939's great DMX library with added support for the EA LPC4088 QuickStart mbed-enabled board. I have added support and tested the 3 UARTs which are accessible on the DIP pins. This forked of okini3939's library was created in the hopes a pull request could be accepted and re-integrated into the library. Important Note: To use the special UART on "pins 41" (rx) and "pin 42" (tx) you must access them by their port names, which are P0_3 (rx) and P0_2 (tx), because the symbols p41 and p42 do not exist in the mbed world (yet).
