/* The LM32F120 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
