VDIP1 (Vinculum - FTDI) problems

[mister_e]

i have some sample in stock since i saw the advert in Electronmic Design magazine... never had any time to mess with since then... by the book, it's suppose to do what you need

Funky enough.. you can find some example on GHI website

I feel USBWiz could be easier to use but ~ 24 USD against ~12 USD for max3421e in single quantity.

The VDIP1 is a fussy feeder and you only find out what it does not like after you have tried and lost data.

After several emails from the factory I have sort of got a working system. I have found out the hard way that not all USB memory sticks are created equal. My Rundisk 2 GB brandx stick is apparently too slow for the Vinculum VDIP1. That may be rectified with proper handshaking but how to do that is nowhere described in the manuals that I have found.

You are meant to be able to upgrade the code in the VDIP1 by inserting a memory stick with an specially named file on it. Well it does work with a Verbatim 512 MB card but my Rundisk 2 GB card just dies part way into the boot load process leaving one VDIP1 module permanently inoperative. Scratch $35.

With a Verbatim 512 MB card I can write 10,000 character files without using any software flow control but I do need some delays.

Now for the task of reverse engineering the flow control system until it works.

I finally got this working with some help from FTDI. I have put a writeup and the full code in the "Code Examples" part of this forum.

Hello friends,
Can anybody guide me how to link VDIP1 module with hyperterminal for testing purpose?
