LPC2368的IAR下读SD卡例程

######################################################################## # # MassStorage.eww # # $Revision: 1.1.2.2 $ # ######################################################################## DESCRIPTION =========== This example project shows how to use the IAR Embedded Workbench for ARM to develop code for the IAR LPC-2378-SK board. It implements a MMC/SD card drive. 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 memory card drive will appear as F:\. The LCD backlight will indicate drive activity. COMPATIBILITY ============= The MassStorage example project is compatible with, and works as a standalone project, on the IAR LPC-2378-SK evaluation board. By default, the project is configured to use the J-Link JTAG interface. CONFIGURATION ============= After power-up the controller get clock from internal RC oscillator that is unstable and may fail with J-Link auto detect, therefore adaptive clocking should always be used. The adaptive clock can be select from menu: Project->Options..., section Debugger->J-Link/J-Trace JTAG Speed - Adaptive. Make sure that the following jumpers are correctly configured on the IAR LPC-2378-SK evaluation board: PWR_SEL - depending of power source USBC/USBSC - USBSC RST_E - unfilled ISP_E - unfilled GETTING STARTED =============== 1) Start the IAR Embedded Workbench for ARM. 2) Select File->Open->Workspace... Open the following workspace: <installation-root>\arm\examples\NXP\LPC23xx\IAR-LPC-2378-SK\ MassStorage\MassStorage.eww 3) Run the program. 4) 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. 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.
