has at least one product using the FT2232 and I think Don Powrie has written an article about the FT2232. He usually puts links to his articles on his company page. Maybe he might be able to help you.

Hello,



I am hitting a wall with the FTDI FT2232. I want to use the first channel in MPSSE mode and the second channel in Bitbang mode.



First problem: I don't find anything in the D2XX docs about how to talk to the second channel.



Second problem: Trying with libftdi on Linux, as soon as I have the command active, that I think should get the second channel into bitbang mode, the MPSSE machine on the first channel goes astray. After emitting some commands to the MPSSE machine, I expect to be able to read two bytes. This is the case with BITBANG mode on the second channel not set. When I have set BITBANG mode the other channel, the read buffer is full (0x1000 bytes available) in the same situation.



Has anybody used the FT2232 successfull in a similar situation?



Thanks
