Hi, I have designed a board around a Stratix II and I am looking for a quicker and more efficient way to get data from the FPGA (registers read, writes, etc) than using I2C. I do not need to pr...

I am currently looking at using the FT245R which seems extremely easy to interface to the Stratix II and will be used to read/write data to the FPGA.

But, I also see that another chip from FTDI, the FT2232. After reading a few resources, I see that people are easily interfacing these chips to both read data and program the FPGA on the fly. (http://www.ftdichip.com/documents/datasheets/morph-ic/ds_morphic.pdf)

I am wondering if it really is this easy, and if I should include this interface too. Does anyone have experience with the FT2232 and the MPSSE. Is it going to be quite a bit more hassles than just using the FT245R and simple commands to interface to the Stratix II?

If easy enough, I wouldn't mind adding this programming interface, but am not too sure of the complexity.

Anyone have any experience with this?
