/* The RDDRONE-BMS772 has one RGB LED:
*
* RedLED PTD16 (FTM0 CH1)
* GreenLED PTB13 (FTM0 CH1)
* BlueLED PTD15 (FTM0 CH0)
*
* An output of '0' illuminates the LED.
*
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
* the RDDRONE-BMS772. The following definitions describe how NuttX controls
* the LEDs:
*
* SYMBOL Meaning LED state
* RED GREEN BLUE
* ---------------- ------------------------ --------------------
* LED_STARTED NuttX has been started OFF OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF ON
* LED_IRQSENABLED Interrupts enabled OFF OFF ON
* LED_STACKCREATED Idle stack created OFF 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 FLASH OFF OFF
* LED_IDLE S32K144 is in sleep mode (Optional, not used)
