atmel 9263 的lcd程序

The Blinky project is an example program for the AT91SAM9263
using Atmel AT91SAM9263-EK Evaluation Board and demonstrating 
interrupt functionality and display to graphic LCD.

Example functionality:                                                   
 - Displays rotating ARM 3D logo, each picture is displayed every 
   200 ms
 - 2 LEDs blink (DS1 and DS2) with speed of 1 second, determined 
   by Periodic Interval Timer (PIT) working in interrupt mode

Clocks: Oscillator =  16.367660 MHz
        PLLA       = 200.049178 MHz
        Processor  = 100.024589 MHz

The Blinky program is available for target:
  SAM9263 Ext SDRAM: configured for external SDRAM (64MB)
                     downloaded to external DataFlash (8.25MB)
                     (used for target debugging and production)

Important: !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!   In EVAL version of uVision do not rebuild the target as !
!   this example's size exceeds EVAL version limitation     !
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Notes: 
  - For "SAM9263 Ext SDRAM" target if Debug is selected 
    the code is loaded to External SDRAM and debugging happens there, 
    if Download to Flash Memory is selected the code downloads to 
    External DataFlash Card
  - Bootloader has to be downloaded to flash for "SAM9263 Ext SDRAM"
    version to work as standalone. This is done by opening 
    Bootloader project and clicking on "Download to Flash Memory" 
    button.

How to start:
  1. Open Bootloader project and click on "Download to Flash Memory"
     button
  2. Click on "Download to Flash Memory" button
  3. Reset the board

Picture conversion procedure:
  1. Convert picture to 32 BPP (X-8bits, B-8bits, G-8bits, R-8bits)
  2. Remove header from bmp by hex editor, remaining file size should 
     be equal to (width * height * 4) bytes
  3. Convert prepared file without header to C array and include it 
     into project source files
