+/// !!!Purpose
+///
+/// The %Dma driver is a high level dma driver which performs DMA device Initializes,
+/// tansfer mode configuration and dma transfer.
+///
+/// !!!Usage
+///
+/// -# Initializes a %Dma controller and dma transfer instance.
+/// Initializes dma for specified channel using DMAD_Initialize().
+/// -# Configures the %Dma transfer buffer by giving transfer mode, transfer mode
+/// for source peripheral and destination peripheral could be single buffer or
+/// multi-buffer(LLI/auto-reload/contiguous buffers) with or without
+/// Picture-In-Picture mode.
+/// DMAD_Configure_Buffer()
+/// \code
+/// // Configure multi-buffer transfer with source address auto-reloaded and
+/// contiguous destination address.
+/// DMAD_Configure_Buffer(DMA_CHANNEL_1,
+/// DMA_TRANSFER_RELOAD,
+/// DMA_TRANSFER_CONTIGUOUS,
+/// 0,
+/// 0);
+/// \endcode
+/// -# Configures the %Dma characteristics (such as source/destination
+/// single transfer width, buffer transfer size and source/destionation
+/// start addreass for the device corresponding to the specified channle
+/// using DMAD_Configure_TransferController().
+/// -# Starts a %Dma transfer using DMAD_BufferTransfer().
+/// The transfer is performed using the %Dma channels.
+/// -# Initialize the total size to be transfered.
+/// -# Initialize the callback function if specified.
+/// -# Enable the interrupt for specified %dma channel.
+/// -# Enable the specified %dma channel.
+/// -# Example for transfering buffer through the %Dma.
+/// \code
+/// // Start channel 1 transfer. Source image auto-reload 4 times.
+/// and transfer to destination continguous.
+/// DMAD_BufferTransfer(DMA_CHANNEL_1, bufferSize * 4, TestCallback, 0);
+/// while (!DMAD_IsFinished(DMA_CHANNEL_1));
+/// \endcode
+/// -# The DMAD_Handler() must be called by the DMA Interrupt Service Routine
+/// with the corresponding %Dma instance. It is invokes to check for pending
+/// interrupts.
+/// - Example for initializing %Dma interrupt handler in upper application.

+/// This directory contains several sub-directories, each one corresponding to

+///
+/// Each subdirectory inside this one provides code for fully-fledged drivers.
+///
+/// Drivers APIs provide high-level unified interface of functions to drive
+/// %interlnal Flash interface, tsd interface, %Twi interface and so on.
+/// However, they do not provide low-level functions to use of AT91 peripherals;
+/// such code can be found in the #perpherials# directory of at91lib.

+/// !!!Purpose
+///
+/// The font.h files declares a font structure and a LCDD_DrawChar function
+/// that must be implemented by a font definition file to be used with the
+/// LCDD_DrawString method of draw.h.
+///
+/// The font10x14.c implements the necessary variable and function for a 10x14
+/// font.
+///
+/// !!!Usage
+///
+/// -# Declare a gFont global variable with the necessary Font information.
+/// -# Implement an LCDD_DrawChar function which displays the specified
+/// character on the LCD.
+/// -# Use the LCDD_DrawString method defined in draw.h to display a complete
+/// string.

+/// \unit
+///
+/// !!!Purpose
+///
+/// This unit provides a very powerful touchscreen driver which handles all the
+/// complexity. This includes touchscreen calibration, retrieving measurements,
+/// configuring the TSADC, etc.
+///
+/// !!!Usage
+///
+/// -# Call TSD_Initialize() whenever the touchscreen should start the
+/// calibration process (as it is done in the function).
+/// -# Declare a global TSD_PenPressed function anywhere in your code. This
+/// function will get called every time the pen is pressed on the screen.
+/// -# Declare a global TSD_PenMoved function, which will get called whenever
+/// the pen stays in contact with the screen but changes position.
+/// -# Declare a global TSD_PenReleased function, which will be invoked as the
+/// pen is lifted from the screen.

+ // by the touchscreen ('c' is any of the calibration points):
+ // dx = (p.data[0] - c.data[0]) / (p.x - c.x)

+ // p.x = c.x - (p.data[0] - c.data[0]) / dx
+ // p.y = c.y - (p.data[1] - c.data[1]) / dy
