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).

 * A library for providing a common base class for Graphics displays
 * To port a new display, derive from this class and implement
 * the constructor (setup the display), pixel (put a pixel
 * at a location), width and height functions. Everything else
 * (locate, printf, putc, cls, window, putp, fill, blit, blitbit) 
 * will come for free. You can also provide a specialised implementation
 * of window and putp to speed up the results
