Communicating with an ALFAT SD for fast SD data logging

Hi,
I try to use the GHI ALFAT SD breakout board with an arduino for fast data logging.
There is a c-libary avaible but it's not written for arduinos.

Does anybody managed to communicate with the ALFAT chipset through an arduino?

Actually I am trying to use it through UART directly using a serial port adapter, without success.
The manual was not very helpful.

Any ideas are very welcome.

I have looked at the code and it is for PC I think, so the libraries need to be rewritten.

The best way is to start from scratch but use the interface to be compatible with existing documentaton. Could be a nice class (OO iso functional)

If you post your code you have sofar we might be able to help
