I followed the instructions on Adafruit but I could never get python to access the IO. The device used SPI to output data in parallel from different pins at each positive clock edge. Unable to add item to List. Most all of their boards have extensive howto's and lots of data. applications include adding USB Flash drive connectivity to a wide All I needed to do was send the FTDI the command to toggle the pin representing the serial clock (which was also the serial clock for the SPI device), extract the status of the FTDI input pins, parse them, and repeat until the full amount of data bits were extracted. The only hiccup I had was in getting the usb library added to python on the Windows PC. You will find some very good info there. What can the FT232H chip do?

The server initializes the board and runs in the background awaiting commands. However, after several weeks of research that involved compiling drivers from scratch, applying janky python pathes/"fixes" and three versions of python, and using multiple PC/linux combinations, I can only conclude that the current linux ftdi driver is not compatible with this hardware. Lot more set-up than expected, but it works just as expected. The board uses a micro USB connector so you can't use the mini to standard cable that comes with the BBB. So as you can see this makes a very simple and clean way to control I/O bits on the BBB or any computer. This breakout has an FT232H chip and an EEPROM for onboard configuration.
