-TFT LCDs
-========
-
-The top level of this folder contains generic drawing routines for 16-bit TFT
-LCD displays.  The core drawing functions are defined in drawing.c, and the
-specific HW implementation of these routines (setting the individual pixels,
-initialising the display, etc.) takes place in a seperate HW drivers that
-implements the methods defined in lcd.h.  To change the LCD used, you simply
-need to change which HW-specific file is compiled and linked during the build
-process, without having to change anything else in your application code.
-
-For example:
-
-- main.c             - drawing.c          - hw\ili9325.c
-----------------     ----------------     ----------------
-  APPLICATION    --> GENERIC DRAWING  -->   SPECIFIC HW 
-     CODE        -->       CODE       -->      DRIVER
-----------------     ----------------     ----------------

-drawing.c          Generic drawing routines such as drawing pixels, lines,
-                   rectangles, as well as basic text-rendering.
-
-lcd.h              This file contains the prototypes of HW-specific functions
-                   that must be implemented in the LCD driver, since
-                   drawing.c will redirect all requests to these lower level
-                   functions.
-                   
-touchscreen.c      Contains a very simple example of how to use ADC to read
-                   the current position on a touchscreen.  No signal debouncing
-                   takes places, and this code will need to be improved for us
-                   in a real-world situation.
