CompactFlash Commands
Introduction
This chapter describes four of the CompactFlash commands, the ControlFlash
Data Working Tag, and how to determine the number of bytes to read or write.
The file system has the ability to perform a variety of operations to read or
write data to the CompactFlash card. There are four basic commands that you
can access:
• Create a file
• Write to a file
• Read from a file
• Delete a file
There is an additional command, verification if a CompactFlash card is
present, but as a user you will not access this, this runs as a background check.
