USB to USB flash Drive File Copier

[mackrackit]

You have to tell the VDIP what to do at all times. It will read the files but then you have to have someway to "remember" what the file name and extension is if you want to do anything with it.

So that is why I used an array. The app I was doing all of the files were DAT so I did not have to worry about that part of it.

I've finally bought a max232 but i cannot find any schematic to connect it to the vdip and and also its connection to the computer. do you have any schematics that you can share with me? even just pin connections will do..

Google must have been down for awhile when you tried to find the info. It is working now though. Here is one of the things that came up.
Look at post #34

And the data sheets for almost any part can be found on google too.

Ive finally connected it into the computer's serial port and the vdip2 responded very well. i can already issue copy commands and the files were indeed copied from the source disk to the target disk. the problem is when i try to enter a sub directory, it only prints $00 $00 $00 $00... have you encountered this? I really need to view the files in the sub folders for file browsing.

Cool!!! You are making progress.

I did not play with sub directories much, I was just writing file to the root directory. But I do remember trying it.

Are you using the Extended Command Set with your firmware?

Looking at the
Vinculum Firmware User Manual
Version: 2.3
Issue Date: 2007-12-03

On page 30 section 6.2.1 Directory (DIR)
This statement is made:

Note that if the specified file is a directory, a size of zero will be displayed rather than a listing of the files in that directory.

So maybe you are there and do not know it???

I should thank you because you shared your knowledge with me that's why my project is developing. However, knowing the note from the firmware really hurt my feelings. how will i ever manipulate the file names for the file transfer if i cannot view them? Ive read in one of their manuals that the vdip can go down to 16 sud directories, how can they say that if they would only print zeroes?

Are you saying that I hurt your feelings?
I only ran across that note about five minutes before I posted it after looking through the manual for clues to your problem.

If I knew how to do what you are wanting I would gladly tell you how.

After you receive the zeros, what happens if you send another DIR command?

The manufacturer also has tech support if all else fails.
