Windows

To access the MPSSE mode of the FT232H on Windows we need to install special drivers and software. We'll use a tool called

Zadig to replace the FTDI driver for the FT232H with a libusb-based driver required by libftdi. Then we'll download a libftdi binary

and install it for Python to access. Finally we'll install the Adafruit Python GPIO library. Carefully follow the steps below to setup

the software.

Note: When you enable MPSSE mode the serial UART driver will be disabled. If you want to disable MPSSE mode and enable

the serial UART again I'll show instructions at the end of the page.

First before you get started make sure you have Python 2.7 installed. You can download the latest Python 2.7 installer

here (http://adafru.it/eaH) (at the time of writing it's version 2.7.8, but any 2.7.x version should work--unfortunately the 3.x series

isn't supported yet). Download the MSI installer for your version of Windows, either 32-bit or 64-bit, and run the installer. Install

Python into its standard location, typically C:\python27. Also make sure to install the option to add Python to the system path so

you can easily call the Python interpretor from a command terminal.

libusb Driver Install

Download the appropriate Zadig tool for your version of Windows at its homepage (http://adafru.it/eaI). This tool simplifies the

installation of a libusb driver for the FT232H device.

Before you run the tool unplug all FTDI devices from your computer. This includes devices likebArduinos which include an FTDI

chip as a USB to serial converter. You want to unplug these devices to make sure you don't accidentally select one with the tool

and replace its driver.

After all the FTDI devices are unplugged, plug in your FT232H breakout to the computer so it is the only FTDI device connected

to the computer.

Now run the Zadig tool executable you just downloaded (there is no installation necessary, the executable is the program). Click

the Options menu and select the List All Devices item below:

The list box of devices should populate with many devices. Select the USB Serial Converter device shown below.

Note: Make sure to select the device with Driver equal to FTDIBUS and USB ID equal to 0403 6014! If you pick the wrong

device you might accidentally uninstall another device's driver and make it inoperable.
