So I compiled and installed it myself for Python 3. You can use these GPIO pins to turn on and off devices or LEDs, or read switches or pins from other chips. Hi, I have a FT232H connected to a 16 ch servo controller over I2C. If you want to disable MPSSE mode and enable the serial UART again I'll show instructions at the end of the page. Welche Punkte es bei dem Kaufen Ihres Adafruit oled library zu untersuchen gilt! FT232H.use_FT232H() # Find the first FT232H device. Port of display drivers from https://github.com/adafruit/micropython-adafruit-rgb-displayto Adafruit CircuitPython for use on Adafruit's SAMD21-based and other CircuitPython boards. The reference for all information about the FT232H. The aren't any configuration or setup options you need to change or worry about in the installation. import Adafruit_GPIO.FT232H as FT232H # Temporarily disable the built-in FTDI serial driver on Mac & Linux platforms. One thing to note is that his library is currently only supported on Mac OSX and Linux. Click open and you should see an empty terminal screen appear. From my point of view, this can be closed. Also notice the show() function is again called after updating pixel colors in order to make the LEDs light up with the desired colors. Move on to the next section to see how to use the MPSSE mode to access GPIO, SPI, I2C, etc. Install Python into its standard location, typically C:\python27. This tool simplifies the installation of a libusb driver for the FT232H device. Adafruit Industries LLC. First make sure the FT232H breakout is plugged in to the computer. Follow the steps here to use device manager to uninstall and remove the driver for the FT232H board. But there might be a problem with writeto_then_readfrom in Blinka and this will be triggered by other driver for other hardware. The next section performs a few simple animations that turn each pixel on with primary colors. 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. The FT232H has the following advanced features: Single channel USB to serial / parallel ports If there is no Ports (COM & LPT) – USB Serial Port (COM6) in the device manager, but you have installed the FTDI driver – see if there is Universal Serial Bus controllers – USB Serial Controller. That's all there is to use GPIO on the FT232H board! One interesting use of the SPI protocol is driving the colors of WS2811/WS2812 NeoPixel addressable RGB LEDs. First connect your FT232H board to the machine and follow the Zadig tool steps here to enable the libusb-based driver for the FT232H board. This is a nice library to access the MPSSE functionality of the FT232H, and is an alternative to the Python GPIO library shown in this guide. import Adafruit_GPIO as GPIO import Adafruit_GPIO.FT232H as FT232H # Temporarily disable the built-in FTDI serial driver on Mac & Linux platforms. Now run the following commands in a terminal in order to install libftdi and its dependencies: The commands above should complete without any errors. These LEDs don't actually use SPI to communicate, instead they have a very specific self-clocked signal for sending pixel color bits. Interested in learning more about the FT232H and its capabilities? You should see a new top level node libusbK USB Devices and the USB Serial Converter underneath it as shown below. You should see a list of devices, such as: Now connect the FT232H breakout to the computer, wait a moment, and run the same ls command again. Run the following command in the terminal to open the serial UART: Replace the /dev/tty.usbserial name with the name of the device you found after running the ls commands above. Once libusbK is enabled as the driver for the FT232H then download the libftdi Windows binaries from here (at the time of this writing you want the libftdi1-1.1_devkit_x86_x64_21Feb2014.zip archive). This breakout has an FT232H chip and an EEPROM for onboard configuration.You can read tons more about this chip from FTDI's page, and check out Adafruit's tutorial on how to get started and use our Python code to control the FT232H with Mac/Win/Linux. I eventually found and installed them -- they were in a different folder of the same website as the 32-bit binaries. This is required to compile and build libraries from source. From the libftdi archive folder, copy all the .DLL files from the bin folder into the Python site-packages folder, specifically: Then also copy in the files from the python2.7 folder of the libftdi archive into the Python site-packages folder: To double check you copied in the right files, your Python site-packages folder should have at least the files below inside it (you might see other files & directories, but don't worry they can be ignored): That's all you need to do to install libftdi. import Adafruit_GPIO.FT232H as FT232H # Temporarily disable FTDI serial drivers. To quit the Python interpretor enter the following: Note on OSX 10.11 El Capitan and higher you might need to permanently disable Apple's built in FTDI serial driver in order to use all of the FT232H's functions.

Adafruit GPIO library. It was last The Python GPIO library that was installed includes a small wrapper around MPSSE functions to simplify the use of reading and writing SPI data. You should follow the same steps to solder the header pins to the FT232H breakout board. 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. Open another Explorer window and navigate to the location you installed Python earlier, typically C:\python27. The adafruit article about using the FT232H board mentions different libraries. This is just a standard Python idiom for defining the main entry point of a program. Next the setup() function is called on the FT232H object. Plug in FT232H & Fix Driver with Zadig Unlike Mac or Linux, Windows doesn't like devices that are 'driverless' - every hardware device must have a driver attached to it. Once any necessary serial port drivers are installed, you're ready to use the FT232H as a USB to serial UART. The commands above should complete without any errors. The time module will be used to delay for a short period of time. It's important to run as administartor or else the driver installation will fail to copy files to Window's system directories. Interface Driver: ftdi This driver is for adapters using the MPSSE (Multi-Protocol Synchronous Serial Engine) mode built into many FTDI chips, such as the FT2232, FT4232 and FT232H. This revision is completely back-compatible for board size, mounting holes and pinouts (the additional 3V/GND pins are where previously there were none and do not change the pinout, they can be left disconnected). Sure you can program an Arduino or Trinket to talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself?
