The Blinky project is a simple program for the LPC2468
using Embedded Artists boards:
  Daughter Board - 'LPC2468 OEM Board v1.1'
  Mother   Board - 'OEM Base Board Basic v1.1'
and demonstrating interrupt functionality.

Example functionality:                                                   
 - Clock Settings:
   - XTAL             = 12   MHz
   - PLL              = 288  MHz
   - processor clock  = 57.6 MHz
   - USB clock        = 48   MHz
   - peripheral clock = 14.4 MHz
 - UART1 settings
   (baudrate = 9600, 8 data bits, 1 stop bits, no parity)
 - Timer0 timer is activating clock_1s every 1 second, 
   starting AD conversion on channel 0 
   (every 1 ms), it works in interrupt mode
 - AD conversion is done in interrupt mode
 - AD value of channel 0 is sent every 1 second on UART1
 - 4 LEDs blink with speed depending on AD value of channel 0
   (LEDs are connected through I2C LED Dimmer (PCA9532))
 - SDRAM and NOR flash interfaces are initialized
 
The Blinky program is available in different targets:
  Simulator:         configured for software Simulator
  LPC2468 Flash:     runs from Internal Flash located on chip
                     (used for production or target debugging)
  LPC2468 Ext SDRAM: configured for External SDRAM 
                     (used for target debugging)
