The demo is configured for Arch Pro. If you use a different board,
open main.cpp and modify the LED values. For example, to modify the
example for the FRDM-K64F, change the LED structure to:

static const LedInfo ledInfo[] = {
   {
      "LED 1",
      LedColor_red,
      1
   },
   {
      "LED 2",
      LedColor_green,
      2
   },
   {
      "LED 3",
      LedColor_blue,
      3
   }
};

You should also delete: DigitalOut  led4(LED4);
