Has anyone had sucess hooking-up the Elektor USB-RS232-SD stick (Elektor-Nov 2006) to the Arduino? If so, please inform how u did it, and what u are able to do with it.
Attached is a link to the stick where some files are a free download.
Regarding the above device... how fast can it write, and how reliable is it?
I'm looking to log at a data rate of about 2k bytes per second. I know that's slow as far as USB goes, but I don't know about that device, or the arduino.
It should be reliable, problems you would encounter I suspect would be more code orientated.
You may need to implement handshaking if you get buffer over runs.
It will need a baud rate at least twice the data rate, 57,600 Baud(6Kb approx) would be my first try.
The amount of processing the Arduino is undertaking will make a difference.
I would log the data to a PC first, I use cutecom terminal. Then when that is working move to the usb logger.
You absolutey must implement handshaking to get any sort of substantial data rate with the Vinculum (VDIP) device. The device needs to be left alone at seemingly random times, and if you write to it during those times it will drop the data.
