/* The UCANS32K146 has one RGB LED:
|
|
*
|
|
* RedLED PTD15 (FTM0 CH0)
|
|
* GreenLED PTD16 (FTM0 CH1)
|
|
* BlueLED PTD0 (FTM0 CH2)
|
|
*
|
|
* An output of '1' illuminates the LED.
|
|
*
|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
|
|
* the Freedom K66F. 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 K66 is in sleep mode (Optional, not used)
