Adafruit FT232H Breakout - General Purpose USB to GPIO+SPI+I2C

Product Information

The adapter can support more than one transport protocol, so OpenOCD allows you to select the transport protocol: Then remove your default FTDI driver. You can use a tool from FTDI called CDM Uninstaller x.x - Windows Device Driver Uninstaller: Just enter your VID and PID. 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. Upgrading a passive DB9 RS232 Interface to an active USB Interface using an FTDI DB9-USB-RS232 Module

Learn how to make flashing your ARM-based MCU easy by using OpenOCD debugger with an FT2232H adapter. Or you can build it from source code, the hard way! This is the route I chose to go, personally. You can find useful guides on how to do this,like the one from Dangerous Prototypes (for Windows), or eLinux(for Linux). You can also read compilation instructions from OpenOCD source code ( README.Windowsand README). You should also tell OpenOCD the initial values of the FTDI GPIO data and direction registers through the ftdi_layout_init command. You should first put the initial values of the channel’s 16 pins, and then the directions. Knowing that "1" is for selecting direction as output and "0" isfor input, and each channel in ft2232H has 16 pins. Selecting OpenOCD as your debugging tool with anadapter like FT2232H is a very good choice when you don’t have much budget to work with.Operation configuration mode and USB Description strings configurable in external EEPROM over the USB interface. D4 - DTR or data terminal ready pin. Another optional pin for flow control in RS-232 serial connections. Wouldn't it be cool to drive a tinyOLED display, read a color sensor, or even just flash some LEDs directly from your computer? Sure you can program an Arduinoor Trinketto talk to these devices and your computer, but why can't your computer just talk to those devices and sensors itself? Well, now your computer can talk to devices using the Adafruit FT232H breakoutboard! Connect TDI to SWDIO via a suitable series resistor (220-470 Ohm or so depending on the drive capability of the target and adapter) connect TDO directly to SWDIO.”

First, make a special configuration file to our adapter. Create a new txt file (ANYNAME.cfg). Remember to edit the VID/PID and serial to match your chip: #This configuration file is created for a tutorial: The FT232H I have seems to be unable to supply its information when using FTD2XX drivers, hence my original post to understand how I might correct this.It could also be caused by a bad configuration like missing ftdi_layout_init command from configuration file:

Once the installation is done you might need to reboot your machine if the installation program tells you to do so. Supports a half duplex FT1248 interface with a configurable width, bi-directional data bus (1, 2, 4 or 8 bits wide).

Note:Defining the SWD_EN signal is important for makingOpenOCD work, even though we didn’t connect it physically. If we don't, an error will appear: To communicate with our target chip, we need a program on the hostand hardware as a bridge between the host and the chip. In this tutorial, we will use OpenOCD as the program on the host to send commands and communicate using SWD. We'll use an FT2232H as the bridge to translate signals from the USB port to the SWD interface.
