/* 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 the I/O PE9 of the STM32F303VCT6.
|
|
* User LD4: blue LED is a user LED connected to the I/O PE8 of the STM32F303VCT6.
|
|
* User LD5: orange LED is a user LED connected to the I/O PE10 of the STM32F303VCT6.
|
|
* User LD6: green LED is a user LED connected to the I/O PE15 of the STM32F303VCT6.
|
|
* User LD7: green LED is a user LED connected to the I/O PE11 of the STM32F303VCT6.
|
|
* User LD8: orange LED is a user LED connected to the I/O PE14 of the STM32F303VCT6.
|
|
* User LD9: blue LED is a user LED connected to the I/O PE12 of the STM32F303VCT6.
|
|
* User LD10: red LED is a user LED connected to the I/O PE13 of the STM32F303VCT6.
|
|
*
|
|
* 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.
