/* There are three user-controllable LEDs on board the Arduino Due board:
*
* LED GPIO
* ---------------- -----
* L Amber LED PB27
* TX Yellow LED PA21
* RX Yellow LED PC30
*
* LED L is connected to ground and can be illuminated by driving the PB27
* output high. The TX and RX LEDs are pulled high and can be illuminated by
* driving the corresponding
* GPIO output to low.
*
* These LEDs are not used by the board port unless CONFIG_ARCH_LEDS is
* defined. In that case, the usage by the board port is defined in
* include/board.h and src/sam_leds.c. The LEDs are used to encode OS-related
* events as follows:
*
* SYMBOL MEANING LED STATE
* L TX RX
* ------------------- ----------------------- -------- -------- --------
* LED_STARTED NuttX has been started OFF OFF OFF
* LED_HEAPALLOCATE Heap has been allocated OFF OFF OFF
* LED_IRQSENABLED Interrupts enabled OFF OFF OFF
* LED_STACKCREATED Idle stack created ON OFF OFF
* LED_INIRQ In an interrupt N/C GLOW OFF
* LED_SIGNAL In a signal handler N/C GLOW OFF
* LED_ASSERTION An assertion failed N/C GLOW OFF
* LED_PANIC The system has crashed N/C N/C Blinking
* LED_IDLE MCU is is sleep mode ------ Not used --------
*
* Thus if LED L is statically on, NuttX has successfully booted and is,
* apparently, running normmally. If LED RX is glowing, then NuttX is
* handling interrupts (and also signals and assertions). If TX is flashing
* at approximately 2Hz, then a fatal error has been detected and the system

/* ITEAD 2.4" TFT with Touch
*
* The Arduino 2.4" TFT Touch Shield is designed for all the Arduino
* compatible boards. It works in 3.3V voltage level. It can be directly
* plugged on the Arduino and other compatible boards. It will offer
* display, touch and storage functions for the Arduino board
*
* Features:
*
* 1. Compatible with 3.3/5V operation voltage level
* 2. Compatible with UTFT library
* 3. With SD Card Socket
*
* The Arduino 2.4" TFT Touch shield uses the S6D1121 controller , it
* supports 8-bit data interface. The touch IC is TSC2046.
