/* LM4F LaunchPad *******************************************************************/
/* The LM4F120 LaunchPad has a single RGB LED. There is only one visible LED which
* will vary in color. But, from the standpoint of the firmware, this appears as
* three LEDs:
*
* BOARD_LED_R -- Connected to PF1
* BOARD_LED_G -- Connected to PF3
* BOARD_LED_B -- Connected to PF2
*
* If CONFIG_ARCH_LEDS is defined, then automated support for the LaunchPad LEDs
* will be included in the build:
*
* OFF:
* - OFF means that the OS is still initializing. Initialization is very fast so
* if you see this at all, it probably means that the system is hanging up
* somewhere in the initialization phases.
*
* GREEN or GREEN-ish
* - This means that the OS completed initialization.
*
* Bluish:
* - Whenever and interrupt or signal handler is entered, the BLUE LED is
* illuminated and extinguished when the interrupt or signal handler exits.
* This will add a BLUE-ish tinge to the LED.
*
* Redish:
* - If a recovered assertion occurs, the RED component will be illuminated
* briefly while the assertion is handled. You will probably never see this.
*
* Flashing RED:
* - In the event of a fatal crash, the BLUE and GREEN components will be
* extinguished and the RED component will FLASH at a 2Hz rate.
*
* RED GREEN BLUE
* LED_STARTED 0 OFF OFF OFF
* LED_HEAPALLOCATE 0 OFF OFF OFF
* LED_IRQSENABLED 0 OFF OFF OFF
* LED_STACKCREATED 1 OFF ON OFF
* LED_INIRQ 2 NC NC ON (momentary)
* LED_SIGNAL 2 NC NC ON (momentary)
