/* The Freedom K28F has a single RGB LED driven by the K28F as follows:
|
|
*
|
|
* LED K28
|
|
* ------ -------------------------------------------------------
|
|
* RED PTE6
|
|
* BLUE PTE7
|
|
* GREEN PTE8
|
|
*
|
|
*
|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board
|
|
* the Freedom K28F. 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 K28 is in sleep mode (Optional, not used)
