USB to USB flash Drive File Copier
Please help me my thesis is USB to USB file copier with out using Computer
i had read for compatible IC the VINCULUM
can you help me i need to use microcontroller the my problem is the source code
like for the display and commands for how to communicate that both IC can i ask for the codes or sample codes for file transfer and viewing the file tru LCD? thank you hope any one can help me

i am student can you help me for my thesis?

Yes, I and others here will help if you have a direct question, but do not look for someone doing your project for you.
That being said, I have played with a VDIP1 some and two of them connected to a PIC might do the job.
BrianT gave a nice starter example here, it is what I used to get started with the VDIP1.

Thanks
im sorry
i mean just a little things to help me
thank you very much
can I ask for VNC1L firmware then it is needed to burned it to the IC like PIC microcontroller?
and it can be burned only for 1 firmware?
|
I can only talk about the VDIP1 as that is the only one I have used so far.
The VDIP1 comes with firmware burned in from the factory. The firmware can be modified / customized somewhat.
Here is a good page to start
http://www.vinculum.com/
This page has the different firmwares available
http://www.vinculum.com/downloads.html#vfirmware
Near the bottom of that page in applications and utilities. there is a program called
Vinculum Firmware Customiser (V1.1b)
This allows to modify some of the main settings of the firmware. Once the firmware has been modified, if using the VDIP1, copy the firmware to the root of a USB "thumb drive". Placs the drive into the VDIP1, at power up the VDIP1 will load the new firmware from the "thumb drive". This all can also be accomplished via serial port connected to the VDIP1 but the flash/thumb drive is so easy.

thanks
thank you mackrackit
soh it means only 1 firmware can be loaded for every VNCL IC
for my project that IC to transfer a files and i will put an LCD how can i acmmunicate that it is not easy to put a program on PIC rigth? any way
how can i use the PIC microcontroller and VNCL IC?
how they can communicate?
for VNCL firmware i know it has a free defined commands like in VDFC firmware
how can i control that commands if I use PIC microcontroller?
for example i use PIC18F458 how can i configure the output pins of the pic?
since the VNCL can accept the FIFO, UART or SPI. what is the examples codes for the pic like if i use picbasic commands? can i write the codes to manipulate the commands of VNCL but how can i control it to the pins of PIC microcontoller?
thanks, , ,

Up in post #4 I gave you a link showing how to WRITE to the VDIP1.
Here is the code from a project where I am READING from the VDIP1.
The VDIP1 part looks a lot like the writing example from BrianT. I used his same methods.
You should be able to connect two VDIP1s to the same PIC and with a little imagination do the copy.
Have you progrmed a PIC to do anything yet???

guys...what compiler do you use for this code posted above by mackrackit?
|
I use Pic Basic Pro for the compiler and MPASM for the assembler.
Dave

|
thanks for the quick reply...
are these compilers and assemblers downloadable for free? i can only find a demo version and it is just capable of compiling 30 lines.
could you please give me the procedure on how to program the vinculum(vdip2) using pic microcontroller? i'm kind of confused. will the command set of the vinculum be included in the program that will be burned to the pic just like in the code above? i'm new at this so please help me...thank you very much.
|
Everything is free except PicBasicPro.
This sounds like a first project for you. Start with someting like blinking a LED at the push of a switch... Then come back to this, but up in post #4 there is a link showing how to write to the module.
Dave

you are right, this is the first project for me, so i'm really starting from scratch. ive seen post #4 but i have one question, what will i do with that code after compiling it, whats next? will i burn it to the pic? i really need your answer on this to start. thank you.
|
Most that use Pic Basic are probably writing the code using Micro Code Studio, you can use any text editor though MCS is pretty good.
When the code is written and the compile button is clicked MCS starts PBP which is a comand line program. PBP will turn the BASIC code into Assembly code. Then either PM or MPASM starts, this is selectable. PM or MPASM will turn the Assembly file into a HEX file.
The HEX file is what gets written to the PIC.
To get the HEX into the PIC a piece of hardware called a programmer is used. There are many to pick from. The programmer will have software to control the flow of data into the PIC and read back what was written to verify the code on the PIC.
Now the PIC is ready to power up and run.
What all do you have so we can help you get started with some learning code?

i have downloaded the pbp compiler but its just in a demo, it can only compile 30 lines. do you know any alternative compiler?
as for the materials that i have, i have here a pic16f877a and a programmer module for that pic. the vdip2 that i have ordered will be arriving soon.
|
please correct me if i'm wrong,
i will burn the program to the pic, then, i will connect the pic to the vinculum using uart mode. then the pic will be the one to issue commands to the vinculum and there is no need for the 232 connections. is that right?
also, how i'm i going to apply the vinculum command sets such as WRF and CLF ? will the compiler be able to understand them?
|
Have you read the code examples posted here? How to read and write are both here.
As for a compiler, PBP is the only one I will recommend.
Practice blinking LEDs with the demo version and other small things first. Then try something bigger later.
You will not be able to make this work as a first project even if you had the full version of PBP.

about the shorts programs like the blinking leds, i have done that already. i already know how to program and burn in pic micro controller. my only problem is to connect it to the vdip, since this is my only first time to use the vinculum so.. was i right with this statement? :
"i will burn the program to the pic, then, i will connect the pic to the vinculum using uart mode. then the pic will be the one to issue commands to the vinculum and there is no need for the 232 connections"
|
I thought you said this was your first project...
If you know all the basics and read the examples you would have seen that the RS232 chip is not needed if you are bit banging the serial.

sorry for the misunderstanding...what I meant was this is my first project using the vinculum not the pic.
can you please tell me what you know about controlling the vinculum using a pic microcontroller. i need to know more info about this topic.
|
Pretty much what I have done with these are posted above. The above example is a data logger for a GPS. The link to the post from Brian T has the writing example. You can see on the GPS example how to collect data and save it to the module.
To be honest, the VDIP thing works well but is a pain in the _ _ _ .
I purchased two and ended up with one in the logger and the other is collecting dust. The data sheet is hard to follow and if it was not for Brian's post I do not think I could have made it work or would have given up.
If you are having a specific problem I am sure we can work though it.
Let us know.

alright thank you.. i will be working on my project and i will be posting the questions if there will be any problem while doing it (which i know there will)
|
Sir do you think it is possible to connect an external dvd drive to the vdip2? Since it is in usb interface can i write data to the external dvd using the vdip2?
|
Interesting idea.
My first thought was no, I do not think it would be possible.
But if you could find the commands from the drivers that normally run these things then why not??
I bet it will not be easy....
Dave
Always wear safety glasses while programming.
|
so im still gonna be needing driver commands to do it?
i wasn't as easy as i thought, i was thinking that since it has been converted to a usb interface, it would be able to interact with the vdip just like a flash drive with the writing as the burning to the dvd.
|
A couple of things off the top of my head that I am sure you will have to send to the burner somehow is
multi-write ?
finalize disk ?
I have never written a burning program for any platform so I am just guessing.

sir i tried to compile the program that you posted in post no.8, it didn't show any errors but in the middle of assembling the file, the MPASM prompted that there was an error (but didn't say what it is) and the progress bar for the asm file turned red. Did this program work for you? you used 16f877a right?
about the external dvd drive i will work on that as soon as i get my vdip2 working ... thanks!
|
Yes, that was a working program, with a 16F877A. Check your project directory and see what the *.ER and *.ERR files have in them.
A friend brought up the buffering problem with CD burners. Just does not seem like a good project for a PIC.
And another could be problem... You have to tell the VDIP exactly how many characters you will be sending though it.

sir this is what was inside the vinculum.err file
Error[118] C:\PBP\SAMPLES\LABXUSB\VINCULUM.ASM 198 : Overwriting previous address contents (2007)
what does this mean?
|
That is from the configuration line in the code.
Remove or comment out the above line and give it a try.Code:@ __config _HS_OSC & _WDT_OFF & _LVP_OFF & _CP_OFF &_BODEN_OFF
This tells about setting the "configs" in your code.

You will be better of just writing you own code from scratch and use my code for an example. Then you know how everything is set up.
Dave

|
the program has been successfully assembled now. Thank you very much.
I will follow your advice and write my own program from scratch.
i was just wondering...did you use any simulator software for this program before burning it to the pic or you just burned it to the pic right after successfully assembling it?
|
I do not use any simulating programs, never ran across one that I trusted except the one built into MPLAB.
A bread board or two and parts are my simulator

sir do you use the software hyperterminal with the vdip? Are all the commands applicable for the hyperterminal for issuing commands to the vdip also applicable for vdip uart pic programming?
|
I do not use hyperterminal much. The serial communicator built into MCS is what I have been using.
Yes the commands are the same as you would send with a PIC.

sir can you please explain me this part of your code:
SEROUT2 PORTB.3, 24972,["MACKRACKIT",13,10]
SEROUT2 VinRXD,8588,["ECS",13] '7,E = 8588 , TRUE
what do you mean by the numbers such as 24972 and 8588 in this statement? also 13 and 10...
Ive been reading the comments in the code but still im confused..
|
13 , 10 are linefeed and return, look at an ascii table for which is which, good thing to study anyway. The number 24972 tells the compiler what baud rate to use, it's in the book, near the back under tables, very near the ascii table . . .hint, hint. . .

thank you very much for that info...
have you used the command DIR and then printed the list of files to the the LCD?
|
I was "printing" to a terminal window, but a LCD would work also.

|
sir can you please tell me about the whole pin connections of the program back in post #8...
i could not see in there that you used the tx and rx pins of the pic16f877a..
|
Well, I did not use the TX/RX pins. I did not use the hardware ports.
VinRXD VAR PORTD.7 'DATA TO VDIP
FLOWIN VAR PORTD.6 'FLOW CONTROL FROM VDIP
and
PORTB.4 is data from the VDIP.
The other serial connections are to and from a PC. I was to lazy to rig a keypad so I was using a terminal to send data to the PIC to send commands to the VDIP.
You do not need to use the hardware serial ports from the PIC for this. SERIN2/SEROUT2 are fine for reading and writing to the VDIP. Have one other pin from the VDIP for FLOW control, this lets the PIC know if the VDIP is ready for another command.
I never did a schematic for this or I would post it.
