RTFM - FT232H - FTDI UART, JTAG, SPI, I2C

FT232H PINOUT

SERIAL UART

Will work with the automatically installed windows vcp driver. Will detect as 'USB Serial Port (COM 5)'

D0 - TX or transmit pin. This pin is the serial data output by the FT232H chip and should be connected to the RX or receive pin of a serial device.
D1 - RX or receive pin. This pin is the serial data input for the FT232H chip and should be connected to the TX or transmist pin of a serial device.
D2 - RTS or ready to send pin. This is an optional pin for flow control of serial connections.
D3 - CTS or clear to send pin. Like RTS, this is an optional pin for flow control.
D4 - DTR or data terminal ready pin. Another optional pin for flow control in RS-232 serial connections.
D5 - DSR or data set ready pin. Like DTR, this is another optional pin for flow control in RS-232 serial connections.
D6 - DCD or data carrier detect pin. This is an optional pin that is sometimes used in RS-232 serial communication.

INSTALLING OPENOCD

Will work with the autom

WINDOWS

OpenOCD Version >= 0.10 with the libftdi driver is required.
Prebuild binaries of OpenOCD can be downloaded from https://github.com/openocd-org/openocd/releases
Extract the openocd-v0.12.0-i686-w64-mingw32.tar.gz folder
Install the libusbK driver for the JTAG interface
- Download and start Zadig
- Click Options>List all devices
- Select Single RS232-HS and WinUSB driver and click Install Driver.

LINUX

OpenOCD Version >= 0.10 with the libftdi driver is required.
If your package distributor provides this version, use your package manager to install OpenOCD:
For Debian based distributions the terminal command is:

$ sudo apt install openocd
If the package version does not work, it is possible to compile OpenOCD from source (github).
