Datasheet

Now let's test if both the libftdi and Adafruit Python GPIO libraries were correctly installed. In the command terminal run Python by

executing:

python

Once the Python interpretor has loaded, type the following at the >>> prompt:

import Adafruit_GPIO

import ftdi1

You should see no response from the Python interpretor after entering each command like below:

No response from the Python interpretor is a good sign because it means Python was able to successfully load the libraries.

If you see an error message or failure after entering a command, unfortunately something went wrong with the installation of the

library. Go back through the steps above and carefully check that nothing was missed. You want to make sure all the libftdi files

are copied into the Python site-packages folder, and that the Adafruit Python GPIO library installed itself successfully.

Once you've confirmed Python can load the libraries, exit the Python interpretor by typing:

quit()

Congratulations, the MPSSE mode drivers and Python libraries are installed and ready to use! Move on to the next section to see

how to use the MPSSE mode to access GPIO, SPI, I2C, etc.

libusb Driver Uninstall

Should you ever want to disable the MPSSE mode for the FT232H and return to its serial UART mode follow the steps below.

First make sure the FT232H breakout is plugged in to the computer. Then open Device Manager and find the libusbK USB

Devices node and the USB Serial Converter child of that node. Right click the device and select Uninstall as shown below:
