DESCRIPTION
===========

  This example project shows how to use the IAR Embedded Workbench for ARM
  to develop code for the IAR-LPC-214X evaluation board. It implements two
  drives, a RAM disk and a MMC/SD card drive. The RAM disk and the
  memory card drive will be accessible through individual drive letters on
  your PC. The first free drive letters will be used. For example, if your
  PC configuration includes two hard disk partitions (in C:\ and D:\) and a
  CD-ROM drive (in E:\), the RAM disk and memory card drive will appear as
  F:\ and G:\ respectively. The MassStorage example project works
  standalone on the IAR-LPC-214X board.

COMPATIBILITY
=============

  The MassStorage example project is compatible with, and works as a
  standalone project, on the IAR-LPC-214X evaluation board. By default,
  the project is configured to use the J-Link JTAG interface.

CONFIGURATION
=============

  1) Make sure that the following jumpers are correctly configured on the
     IAR-LPC-214X evaluation board:

        PWR_J   - the correct jumper position depends on the power source used
        PWM/DAC - install the jumper in the position marked 2-3 (PWM)
        DBG     - install the jumper
        
  2) Use a USB cable to connect the evaluation board to your PC. The first
     time a USB device is connected to your computer, Windows will
     automatically load the proper device driver. In this case, the USB
     mass storage device driver will be loaded.

GETTING STARTED
===============

  1) Start the IAR Embedded Workbench for ARM.

  2) Select File->Open->Workspace...
     Open the following workspace:

     <installation-root>\arm\examples\Philips\LPC214x\IAR-LPC-214X\
     MassStorage\MassStorage.eww

  3) Run the program.

     The MassStorage application is downloaded to the flash memory on the
     evaluation board and executed. Also note that, during board operation,
     the LCD backlight will indicate drive activity.
