Does anyone know of any software available to take data from the FT2232H in 245 FIFO Sync mode and write it to screen or to a log file?
Basically, I am using the FT2232H IC to transfer a large amount of data from an FPGA over USB. I chose the IC because I've had some experience with FTDI chips before using their VCP (virtual com port) driver and because of the USB2 speeds available.
Unfortunately, it needs to use the D2XX driver, which doesn't allow it to show up as a virtual com port on my windows machine so I can no longer use TeraTerm to display data being sent through the IC.
It seems to me that the FT2232H in sync FIFO mode should be a popular enough option that someone has already written software for a windows machine that would let me see data coming off the USB – either on screen or to a text file. A google search didn't turn anything up and I figured this is a valuable enough question that others might be interested in the answer too.

I've got a test utility that I made for an application that uses a 245 FIFO. You can download the source code for my test program here. It's written in Visual C# Express 2010, which you can download quickly and free to make whatever modifications you want.
As you can see in the picture below, the test utility is extremely specific to my application, so it won't be very useful to you without some minor mods, but my guess is that you could adapt it to do what you want in an hour or two. You can look at the ReadRegister and WriteRegister functions to see how to read/write from the device.
HOWEVER I use the D2XX drivers and I'm pretty sure that I can still access the virtual comm port through a terminal program. So I'm not sure that you really need a D2XX based tool.
Let me know if you need any guidance.
