I ported this directly from the official supplied LPC2129 example. The hardware is the IAR/Olimex LPC2378 board entitled "LPC2378-SK" (2007) Rev. A. If you want to see the changes I suggest you diff the official example with this one. To build the code just unzip the example and find the eww project file in fol Tder ARM7_LPC2378_IAR. Then is should work out of the box. If you have the same hardware I changed the code so that three LED's (one is the LCD backlight) will flash at different rates. Also the serial port does work 38400 8E1. The system tick is 1ms.
