/* The STM32F3Discovery board has ten LEDs. Two of these are controlled by
* logic on the board and are not available for software control:
*
* LD1 PWR: red LED indicates that the board is powered.
* LD2 COM: LD2 default status is red. LD2 turns to green to indicate that
* communications are in progress between the PC and the
* ST-LINK/V2.
*
* And eight can be controlled by software:
*
* User LD3: red LED is a user LED connected to PE9
* User LD4: blue LED is a user LED connected to PE8
* User LD5: orange LED is a user LED connected to PE10
* User LD6: green LED is a user LED connected to PE15
* User LD7: green LED is a user LED connected to PE11
* User LD8: orange LED is a user LED connected to PE14
* User LD9: blue LED is a user LED connected to PE12
* User LD10: red LED is a user LED connected to PE13
*
* If CONFIG_ARCH_LEDS is not defined, then the user can control the LEDs
* in any way. The following definitions are used to access individual LEDs.
