标题: BASCOM-AVR利用AVR-DOS库读写SD卡
试验了用BASCOM读写SD卡，完全可以把SD卡当作磁盘来操作，与VB/QB语法兼容，编程非常简单。

　　AVR-DOS介绍
　　Features:
         ·  Read and writeASCII-Files
·  Read and writeBinary-Files
·  Drivers available forCompact Flash Cards, Hard disk, MMC, SD etc.
·  Completly integrated inBASCOM-AVR Compiler
·  QB/VB compatible syntax
·  Completly written inAVR-Assembler (fast and compact)
　　It workswith:
         ·  DOS-FAT16 and FAT32 formatted partitions
·  Files in Root directory and sub directories
·  Short DOS File names (8.3)
·  Sector Size of 512 Bytes(nearly all CF-Cards and HD)
·  Linear sector addressing(LBA-Mode). (all newer CF-Cards and HD). C/H/S-Mode of old HD is not supported.

　　Please note: AVR-DOS is only free for noncommercial use. For commercial use, or when you are interested in ASM-Code andcomplete documentation please check Licensedirectives

　　Functions:
　　Hereis a list of all in BASCOM-AVR integrated statements, which uses AVR-DOSfunctionality.

　　Disk/Directory:
         ·  InitFileSystem (<Partition#>)
·  DiskSize
·  DiskFree
·  Kill <FileName>
·  Dir ([ <FileName>])
·  FileLen ([ <FileName> ])
·  FileDateTime ([ <FileName>])
·  FileDate ([ <FileName>])
·  FileTime ([ <FileName>])
·  GetAttr ([ <FileName>])
·  Name<OldFileName>As <NewFileName>
·  ChDir<PathName>])
·  MkDir<PathName>])
·  RmDir<PathName>])
　　File create, open, read, write, close:
         ·  FreeFile
·  Open <FileName> ForInput/Output/Append/Binary as #<File#>
·  Close <File#>
·  Flush [<File#>]
·  Print #<File#>,Variable1; Variable2; …
·  Write #<File#>,Variable1, Variable2, …
·  Input #<File#>,Variable1, Variable2, …
·  Line Input #<File#>,StringVariable
·  Get #<File#>,<Variable> [,<Position>]
·  Put #<File#>,<Variable> [,<Position>]
·  Seek #<File#>[,<New Position>]
　　Infos about opened files:
         ·  EOF (#<File#>)
·  LOC (#<File#>)
·  LOF (#<File#>)
·  FileAttr (#<File#>)
　　Others:
         ·  Bload <FileName>,<SRAM-Address>
·  Bsave <FileName>,<SRAM-Address>, <Length>
