試驗(yàn)了用BASCOM讀寫SD卡，完全可以把SD卡當(dāng)作磁盤來操作，與VB/QB語法兼容，編程非常簡單。
AVR-DOS介紹
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>
