Hi,
I have been using libftd2xx to communicate with a FT2232H chip in one of my
devices. This chip has two FIFOs that can be addressed independently over the
same USB interface, and in the case of libftd2xx one uses the serial number
appended with either "A" or "B" to access these two different interfaces.
I am now in the process of porting my software to libftdi and was wondering how
one handles this in this API. When I use the supplied "find_all" example, the
FT2232H chip appear only as one device, not as two as was the case with
libftd2xx. So is the function "ftdi_usb_open_desc_index " the function to use to
accomplish this? If so, would the indexes be "0" and "1"?
Sorry if this is a trivial question that was asked before, I am still kind of
new to libftdi...
thanks,
Jo
