frankvnk 10:d07f76421408 2 This file contains 3 examples:
frankvnk 10:d07f76421408 3
frankvnk 10:d07f76421408 4 ONE : Original example with paint demo.
frankvnk 10:d07f76421408 5 TWO : Example for displaying a bitmap read from SD card.
frankvnk 10:d07f76421408 6 Download the house.bmp bitmap file from http://mbed.org/media/uploads/frankvnk/house.bmp
frankvnk 10:d07f76421408 7 Copy this file to the root of an SD card, insert it into the Mini-DK.
frankvnk 10:d07f76421408 8 THREE : Example for copying a bitmap from SD to flash memory, use it as background and
frankvnk 10:d07f76421408 9 write text without disrupting the background image.
frankvnk 10:d07f76421408 10 Download the house.bmp bitmap file from http://mbed.org/media/uploads/frankvnk/house.bmp
frankvnk 10:d07f76421408 11 Copy this file to the root of an SD card, insert it into the Mini-DK.
frankvnk 10:d07f76421408 12
frankvnk 10:d07f76421408 13 IMPORTANT:
frankvnk 10:d07f76421408 14 Enable #define USE_FLASH_BUFFER in SPI_TFT.h to allow copy to flash.
frankvnk 10:d07f76421408 15 If copy to flash option is not needed - disable it.
frankvnk 10:d07f76421408 16
frankvnk 10:d07f76421408 17 UNCOMMENT THE DESIRED CODE TO TEST.
