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?Originally Posted by newbie
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.

oh no you got me misunderstood.. that just meant that i think I'm in a little bit of a trouble not being able to view the sub directories. I will ask the vinculum's customer support about this matter, and for the mean time i will be concentrating on the files located on the root..i wasn't successful the first time i interfaced the vdip2 to the pic16f877a. I could not get any response from the vdip. all i get are weird characters printed in the lcd even when the vdip is turned off. have you encountered this?

OK. I get what you mean.
Contact teck support and see what they say.
In the mean time post your code and configs along with a schematic here and maybe if we are lucky someone will see the problem.

As you can see I ripped a part of your code. pardon me for doing so. I just wanna see if the vdip would respond to the pic. This program is pretty short, I just wanted to display the first file it detects to the lcd. I wouldn't want to write a long program and then start wondering what part of the code went wrong after wards. Once I get a response even just one file name from the directory then will start to write my own program including the file browsing.Code:DEFINE OSC 20 INCLUDE "modedefs.bas" DEFINE LCD_DREG PORTC DEFINE LCD_DBIT 0 DEFINE LCD_RSREG PORTD DEFINE LCD_RSBIT 1 DEFINE LCD_EREG PORTD DEFINE LCD_EBIT 3 DEFINE LCD_RWREG PORTD DEFINE LCD_RWBIT 2 DEFINE LCD_BITS 8 DEFINE LCD_LINES 4 Define LCD_CHARS 20 DEFINE LCD_COMMANDUS 2000 DEFINE LCD_DATAUS 50 VTXD VAR PORTB.0 VRXD VAR PORTB.1 Flowin VAR PORTB.2 Pause 500 Lcdout $fe,$C0, " Please Insert Your " Lcdout $fe,$94, " Flash Drive " Pause 100 RESP VAR BYTE[16] X1 VAR BYTE X2 VAR BYTE X3 VAR BYTE X4 VAR BYTE X5 VAR BYTE X6 VAR BYTE X7 VAR BYTE X8 VAR BYTE checkvin: SEROUT2 VRXD,8588,["ECS",13] HIGH VRXD PAUSEUS 10 SEROUT2 VRXD,8588,["IPA",13] HIGH VRXD PAUSEUS 10 WAIT1 IF Flowin = 1 THEN WAIT1 SEROUT2 VRXD,8588,["DIR",13] PAUSE 100 SERIN2 VTXD,8588,[STR RESP\8] X1 = RESP[0] X2 = RESP[1] X3 = RESP[2] X4 = RESP[3] X5 = RESP[4] X6 = RESP[5] X7 = RESP[6] X8 = RESP[7] X9 = RESP[8] X10 = RESP[9] X11 = RESP[10] X12 = RESP[11] PAUSE 100 LCDOUT $FE,1,X1,X2,X3,X4,X5,X6,X7,X8,X9,X10,X11,X12 PAUSE 2000

I can now view the files in the sub directories...this is my bad.. I was entering DIR (file), this command would only list the specified file and size. I did not see until now that these was another command that will change the current directory, its CD (folder). my bad sorry. now i can go on and make a program once i get responses from the vdip with the pic controlling it.

Great!!! Progress!!!
No problem ripping the code, that is what it is there for.
Writing a little and testing is the way to do it. That is why ICSP is so handy.
Keep us posted.
