* ------------------- ----------------------- -------- --------
* LED_STARTED NuttX has been started OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF
* LED_IRQSENABLED Interrupts enabled OFF OFF
* LED_STACKCREATED Idle stack created ON OFF
* LED_INIRQ In an interrupt No change
* LED_SIGNAL In a signal handler No change
* LED_ASSERTION An assertion failed No change
* LED_PANIC The system has crashed OFF Blinking
* LED_IDLE STM32 is is sleep mode Not used
