How to drive the Vinculum VDIP1 in UART mode

[page101]

Hello guys, I've been searching around, and finally got here. I am also using VDIP1.

Does anyone tried to send a file from the USB flash drive to the Microcontroller?
I am trying to get a file from my flash drive, a jpg file and I wanted to send it to the monitor or to the UART of the VDIP1. I guess I am having a difficulty which command I will use. I tried to use "RD" command to send the whole content of the JPG file and got lots of values and it lasts for about 10 mins to finish and my VDIP1 hangs up after it so I need to restart it.

And lastly I want to send again the jpg file to the UART of VDIP1 and send it to my flash drive. I can do it for txt file but that involves four steps, OPW, WRF, Content, CLF. I want to try different file types and not anymor txt files.

Does anyone knows what to do about these or just an experience relating to these??? Thanks

Hi.I am pre-final year engineering student from India.
Our project is to copy data from one USB stick to another without use of PC.
I searched a lot about it and I found that VNC1L is suitable for that.
But i don't know from where i should start?
Can anyone please help me??

I tried helping a couple of others get started on the same thing here

I do not know if they had any luck, you might contact them and see.

I wonder if all of you attend the same school? Seems to be a common homework assignment these days.

can you plz provide me schematic to interface VNC1L to MCU?
and which MCU is preferable PIC16F688?
plz help me guys i am @ level 0

hey, can you send me the circuit how you connected VDIP1 to PIC ?

Hi Guys, I have a issue which is driving me nuts...

When I connect either one of my flash drives to the VDIP module, nothing happens...

When I apply VCC 5V to the device the leds blinks alternating then stops this happens when i start the module in spi or FIFO mode with or witout my flash drives. However when i start the module in UART the led's blinks continuously even when i connect my flash drives.

1) Both my flash drives are not working with the VDIP, because they work perfectly on the pc
2) my VDIP is blown, but also unlikely because i can re flash is using my rs323rl board.

Does anyone had this led issue or what to do when vdip does not recognize your flash drives.

Help will be greatly appreciated

hi Jacques,

i think the problem is that the VDIP is unable to send bytes (Confirming that it is online) because of its UART Connection. Can you try to connect the CTS of the VDIP to the ground? may be this will solve it.

Best Regards!

Page 101, youre a rock star thx man,

Now its the tricky task of getting it to work in fifo mode.
