In particular you'll need to tie the D1 and D2 pins together with a jumper wire. The second thing you'll need to do with your circuit is add explicit pull-up resistors from SDA & SCL on the FT232H up to 3.3 or 5 volts. However, FTDI’s hardware has a whole lot more to offer, and [jayben] is here to show us all how to take advantage of it using Python. Note that there are other libraries you might consider using for I2C communication with the FT232H. The interface on the I2CDevice class for reading and writing is exactly the same as the interface on the Raspberry Pi Python I2C code, so you can examine code which is written for the Pi and use it with very few changes on the FT232H. # General implementation that can be improved by subclasses. # Make GPIO constants that match main GPIO class for compatibility. the MISO line. To summarize, for using I2C you need to setup your hardware as follows: To use I2C with the Adafruit Python GPIO library you'll need to create an Adafruit_FT232.I2CDevice instance. that use I2C or SPI and have been ported to Python for the Raspberry Pi & BeagleBone Black, so can you use those boards with the FT232H breakout too? It uses the FT232H as a USB to I2C Master interface It uses the FT201X as a USB to I2C Slave interface This application note has three main aims: - Show how to initialize the FT232H as an I 2C Master and provide example I C functions for using the FT232H as a generic USB to I2C Master interface.

I2C is more complex and sometimes slower than SPI, but only requires two data lines (and a ground) which is desireable in some situations. Read length is an optional argument, so that it can function similar to transfer.
