*
* LD1 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.
* LD2 PWR: Red LED indicates that the board is powered.
*
* And two LEDs can be controlled by software:
*
* User LD3: Green LED is a user LED connected to the I/O PB7 of the STM32L152 MCU.
* User LD4: Blue LED is a user LED connected to the I/O PB6 of the STM32L152 MCU.
*
* The other side of the LED connects to ground so high value will illuminate the LED.
