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 0:ee7076d8260a 6 * To port a new display, derive from this class and implement
frankvnk 0:ee7076d8260a 7 * the constructor (setup the display), character (put a character
frankvnk 0:ee7076d8260a 8 * at a location), rows and columns (number of rows/cols) functions.
frankvnk 0:ee7076d8260a 9 * Everything else (locate, printf, putc, cls) will come for free
frankvnk 0:ee7076d8260a 10 *
frankvnk 0:ee7076d8260a 11 * The model is the display will wrap at the right and bottom, so you can
frankvnk 0:ee7076d8260a 12 * keep writing and will always get valid characters. The location is
frankvnk 0:ee7076d8260a 13 * maintained internally to the class to make this easy
