| /* 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. |
