IMPORTANT NOTES

Loading fonts

When using this libary, don't forget to load the TFT_FONTS library from Peter Drescher at http://mbed.org/users/dreschpe/code/TFT_fonts/

filetoflash (SD to CPU flash)

This library 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 adding following instruction BEFORE you load the library: 

#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).

Sample code

#include "mbed.h"

// SPI TFT
// NOTE : connect the LCD reset pin the reset pin of the CPU board.
//        eg: on the mbed board, this is the 'nR' connection.
#define NO_FLASH_BUFFER         // Do not use CPU flash for storing bitmaps
#include "SPI_TFT_ILI9320.h"
#include "Arial12x12.h"
#include "Arial24x23.h"
#include "Arial28x28.h"
#include "font_big.h"
SPI_TFT TFT(p11, p12, p13, p14,"TFT");  //mosi, miso, clk, cs

int main (void)
{

    TFT.claim(stdout);        // send stdout to the TFT display
    TFT.background(Black);    // set background to black
    TFT.foreground(White);    // set chars to white
    TFT.cls();                // clear the screen
    TFT.set_font((unsigned char*) Arial12x12);  // select the font

    TFT.locate(0,0);
    printf("ILI9320 SPI TFT library\n");
    printf("Simple demo\n");
