/* The NuTiny has a single green LED that can be controlled from sofware. This LED

|
* is connected to PIN17 (PB.0). It is pulled high so a low value will illuminate the LED.

|
*
|
|
* If CONFIG_ARCH_LEDs is defined, then NuttX will control the LED on board the
|
|
* NuTiny. The following definitions describe how NuttX controls the LEDs:

|
|
* SYMBOL Meaning LED state
|
|
* Initially all LED is OFF
|
|
* ------------------- ----------------------- ------------- ------------
|

|
|
* LED_HEAPALLOCATE Heap has been allocated LED ON
|
|
* LED_IRQSENABLED Interrupts enabled LED ON
|
|
* LED_STACKCREATED Idle stack created LED ON
|
|
* LED_INIRQ In an interrupt LED should glow
|
|
* LED_SIGNAL In a signal handler LED might glow
|
|
* LED_ASSERTION An assertion failed LED ON while handling the assertion
|
|
* LED_PANIC The system has crashed LED Blinking at 2Hz
