基于C8051F340的SD卡读写，移植了FATFS的文件系统。可以实现文件的读写。本人验证通过，可对有文件系统的SD进行读写。-Based on C8051F340" s SD card reader, transplant FATFS the file system. File read and write can be achieved. I verified by, a file system can read and write SD.

应用背景Logical separation of program and data memory All 8051 devices have specific memory organization, they have separate address spaces for Program (ROM) and Data (RAM) Memory. This logical separation of Memory is useful because it allows the Data Memory to be accessed by 8-bit addresses, which can obviously be more quickly stored and manipulated by an 8-bit CPU. Of course, the l6-bit Data Memory addresses can still be generated with the DPTR register. Program Memory Program Memory can only be read, not written to. The address space for 8051 core is 16- bit, so there is maximum of 64K bytes of Program Memory. Up to 4 Kbytes of Program Memory can be on chip, internal Program Memory of the 8051 core. For access to external Program Memory is used signal PSEN (Program Store Enable). Data Memory Data Memory is on a separate address space than Program Memory. For external Data Memo

在pc 机的根目录下建立minigui- free 目录，将下载的源代码包copy 到该目录， 解压缩，生成libminigui-1.3.3、minigui-res-1.3.3、mde-1.3.0、mg-samples-1.3.1。 我在该目录中建立nfsroot 目录，用以存放生成的文件。-Pc machine in the root directory of the establishment of minigui-free directory, will download the source code package to the catalog copy, extract, generate libminigui-1.3.3, minigui-res-1.3.3, mde-1.3.0, mg- samples-1.3.1. I create a directory in the nfsroot directory to store files generated.
