/* The Freedom KL25Z has a single RGB LED driven by the KL25Z as follows:
|
|
*
|
|
* ------------- --------
|
|
* RGB LED KL25Z128
|
|
* ------------- --------
|
|
* Red Cathode PTB18
|
|
* Green Cathode PTB19
|
|
* Blue Cathode PTD1
|
|
*
|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
|
|
* Freedom KL25Z. The following definitions describe how NuttX controls the LEDs:
|
|
*
|
|
* SYMBOL Meaning LED state
|
|
* Initially all LED is OFF
|
|
* ------------------- ----------------------- --------------------------
|
|
* LED_STARTED NuttX has been started
|
|
* LED_HEAPALLOCATE Heap has been allocated
|
|
* LED_IRQSENABLED Interrupts enabled
|
|
* LED_STACKCREATED Idle stack created
|
|
* LED_INIRQ In an interrupt
|
|
* LED_SIGNAL In a signal handler
|
|
* LED_ASSERTION An assertion failed
|
|
* LED_PANIC The system has crashed
|
|
* LED_IDLE K25Z1XX is in sleep mode (Optional, not used)
