Overview

PyFtdi aims at providing a user-space driver for popular FTDI devices, implemented in pure Python language.

Suported FTDI devices include:

• UART and GPIO bridges

  • FT232R (single port, 3Mbps)
  • FT230X/FT231X/FT234X (single port, 3Mbps)

• UART, GPIO and multi-serial protocols (SPI, I2C, JTAG) bridges

  • FT2232C/D (dual port, clock up to 6 MHz)
  • FT232H (single port, clock up to 30 MHz)
  • FT2232H (dual port, clock up to 30 MHz)
  • FT4232H (quad port, clock up to 30 MHz)
  • FT4232HA (quad port, clock up to 30 MHz)

Features

PyFtdi currently supports the following features:

• UART/Serial USB converter, up to 12Mbps (depending on the FTDI device capability)
• GPIO/Bitbang support, with 8-bit asynchronous, 8-bit synchronous and 8-/16-bit MPSSE variants
• SPI master, with simultanous GPIO support, up to 12 pins per port, with support for non-byte sized transfer
• I2C master, with simultanous GPIO support, up to 14 pins per port
• Basic JTAG master capabilities
• EEPROM support (some parameters cannot yet be modified, only retrieved)
• Experimental CBUS support on selected devices, 4 pins per port

Supported host OSes

• macOS
• Linux
• FreeBSD
• Windows, although not officially supported
