00002 This file contains 3 examples:
00003 
00004 ONE   : Original example with paint demo.
00005 TWO   : Example for displaying a bitmap read from SD card.
00006         Download the house.bmp bitmap file from http://mbed.org/media/uploads/frankvnk/house.bmp
00007         Copy this file to the root of an SD card, insert it into the Mini-DK.
00008 THREE : Example for copying a bitmap from SD to flash memory, use it as background and
00009         write text without disrupting the background image.
00010         Download the house.bmp bitmap file from http://mbed.org/media/uploads/frankvnk/house.bmp
00011         Copy this file to the root of an SD card, insert it into the Mini-DK.
00012 
00013 IMPORTANT:
00014 If copy to flash option is not needed - enable //#define NO_FLASH_BUFFER in Mini_DK.h
00015 
00016 
00017 UNCOMMENT THE DESIRED CODE TO TEST.
