* arch/arm/src and include/ and configs/sam*/: Large rename of all
references to SPI with SPI0. This is because all other SAMs have
only SPI but the 3X/3A have SPI0 and SPI1 (2013-6-26).
* configs/arduino-due: Complete the basic board configuration and
integrate this into the configuration and build system. The Arduino
Due is now ready to begin test (2013-6-17).

Buttons and LEDs
^^^^^^^^^^^^^^^^
To be provided
Buttons
-------
There are no buttons on the Arduino Due board.
LEDs
----
There are two user-controllable LEDs on board the Arduino Due board:
LED GPIO
---------------- -----
TX Yellow LED PA21
RX Yellow LED PC30
Both 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
RX TX
------------------- ----------------------- -------- --------
LED_STARTED NuttX has been started OFF OFF
LED_HEAPALLOCATE Heap has been allocated OFF OFF
LED_IRQSENABLED Interrupts enabled OFF OFF
LED_STACKCREATED Idle stack created 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 OFF Blinking
LED_IDLE MCU is is sleep mode Not used
Thus if RX is statically on, NuttX has successfully booted and is,
apparently, running normmally. If TX is flashing at approximately
2Hz, then a fatal error has been detected and the system has halted.
Serial Consoles
^^^^^^^^^^^^^^^
To be provided
Any of UART and USART0-3 may be used as a serial console. By default,
the UART is used as the serial console in all configurations. But that is
easily changed by modifying the configuration as described under
"Configurations" below.

PB20 AD11(TXD3) ADCH 4

The outputs from these pins is 3.3V. You will need to connect RS232
transceiver to get the signals to RS232 levels (or connect the pins to the
USB virual COM port.
