/**
 * @mainpage
 * This is an example project for the MSP430-4619LCD development board,
 * which is produced by Olimex Ltd. I've used Linux, but maybe you can use any
 * operating system which has GNU make and mspgcc. The code is from Olimex,
 * ChaN (FatFs) and me.
 *
 * Features:
 * - Simple menu system:
 *   MENU_handler()
 * - MMA test:
 *   mmaBallTest() mmaRawValues()
 * - Measuring VCC and temperature:
 *   showVcc() showTemp()
 * - Keyboard and joystick test:
 *   keyboardTest()
 * - LCD handling. Writing text to display with printf, displaying RGB
 * bitmaps:
 *   LCD_printf() LCD_write130x130bmp()
 *   <br>Usable font included (ProggySquareSZ)!
 * - SD card and DOS filesystem handling: creating, reading files, etc: 
 *   FF_fileTest()
 *   Thanks to ChaN for the FatFs module: http://elm-chan.org/fsw/ff/00index_e.html
 * - MOD-NRF24Lx extension board handling: NRF_send() NRF_receive() <br>
 *   The P85 points of P85/SDA jumper and the P84 points of P84/SCL jumper should be shortened.
 * - Timing functions: RTC, delay, etc.:
 *   TIME_setDate() TIME_getDate() delay() mdelay()
 * 
 * You should set your LCD type (GE8/GE12) in lcd.h! I've got GE8, so if you set GE12
 * maybe doesn't work.
 *
 * Additional tools:
 *  - font2c.pl: PERL script to convert .hex font files to C code. You can create Hex font files
 *  with 'gbdfed'.
 *  - img2c.pl: PERL script to convert pictures (.png, .jpg, etc.) to C code
 *  (12-bit RGB format).
 *
 * Quick how-to for make:
 *  - Type <code>make</code> to compile the code.
 *  - Type <code>make flash</code> to flash program to the MSP430's ROM.
 *  - Type <code>make doc</code> to generate documentation.
 *
 * You can download this sample here:
