Supported features UART Serial port, up to 6 Mbps. 8 minimum. You can use an Arduino or a FTDI programmer to send commands. Note that not all FTDI ports are MPSSE capable. DESCRIPTION: Basically this is a 'FTDI to serial' connection manager. Adafruit has created a guide to show how to use an FT232H to connect to I2C and SPI sensors and breakouts from your desktop PC running Windows, Mac OSX, or Linux. blog # Compatible with Python 2. , PATH on windows, LD_LIBRARY_PATH or standard library directories on Linux) EEVblog Captcha We have seen a lot of robot like traffic coming from your IP range, please confirm you're not a robot Several FTDI adapters can be accessed simultaneously from the same Python runtime instance. However, FTDI’s hardware has a whole lot more to offer, and [jayben] is here to show us all how to take advantage of it using Python. Please ensure you have FTDI drivers installed or available where the linker looks for shared libraries (e. Python Interface for FTDI MPSSE (I2C and MDIO). The LibMPSSE-SPI library has been created to to aid the implementation of SPI designs using FTDI devices which incorporate the FTDI MPSSE (FT4232H, FT2232H, FT2232D and FT232H) by taking care of all the required MPSSE commands. Allows the user to connect (in this example) to an arduino nano with very little hassle by directly connecting to the USB to serial (FTDI) on the device.
