|
|
*
|
|
* LD1 COM: LD1 default status is red. LD1 turns to green to indicate that
|
|
* communications are in progress between the PC and the
|
|
* ST-LINK/V2-1.
|
|
* LD3 PWR: red LED indicates that the board is powered.
|

|
|
* And one can be controlled by software:
|
|
*
|
|
* User LD2: green LED is a user LED connected to the I/O PA5 of the
|
|
* STM32G071RBT6.
|
|
*
|
|
* If CONFIG_ARCH_LEDS is not defined, then the user can control the LED in
|
|
* any way. The following definition is used to access the LED.
