Frank Vannieuwkerke / Mbed 2 deprecated LPC1768_Mini-DK

LPC1768 Mini-DK board with 2.8" SPI TFT and SPI touch

Dependencies:   Mini-DK mbed SDFileSystem

WARNING: filetoflash (SD to CPU flash)

The SPI_TFT library called from Mini-DK.lib contains an option to copy an image from the SD card to the CPU flash memory. This allows you to use an image as background without speed loss when writing other text and graphics.

By default, this option is enabled.

It can be disabled by uncommenting the #define mentioned below in Mini_DK.h: 

#define NO_FLASH_BUFFER

Since the flash memory has limited write endurance, DO NOT use this feature when you intend to read multiple images from the SD card (eg: when used as a photo frame).

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 13:a10300cac491 14 If copy to flash option is not needed - enable //#define NO_FLASH_BUFFER in Mini_DK.h
frankvnk 13:a10300cac491 15
frankvnk 10:d07f76421408 16
frankvnk 10:d07f76421408 17 UNCOMMENT THE DESIRED CODE TO TEST.
