Hello everybody,

I have embedded system which is connected PC’s serialport. In the
embedded system I have compactflash card which is formatted FAT16 file
system. The purpose is to use this compactflash card in visual c++ or
visual basic, but I can’t use those windows file routines(CreateFile,
WriteFile etc…) because the device does not shown as diskdriver in
windows. So have you any idea how I get this device shown as diskdriver?
Perhaps I need some device driver? Where I can find good tutorial how to
write one, I hane microsoft DDK and there was some info, but it’s not
enough…

I forgot to mention that I can read and write sector via rs-232 from/to CF
card…

CF(FAT16) -> RS-232 -> (here I need something) -> windows file routines

You will need to represent your device as a disk device to the OS.

Writing a SCSI port with a single disk LUN is a good solution for
this.

Hi,

      Take a look in to the NTDDK\src\storage. If  they work for you if it doesn’t then you will have to design and Implement a different Device Driver as per your device Low level information.

 

Good luck,
