/* The NuTiny has a single green LED that can be controlled from software.
|
|
* 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
|

|
|
*
|
|
* SYMBOL Meaning LED state
|
|
* Initially all LED is OFF
|
|
* ------------------- ----------------------- ------------- ------------
|
|
* LED_STARTED NuttX has been started LED ON

* LED_PANIC The system has crashed LED Blinking at 2Hz
