Python bindings to d2xx and libftdi to access FT232 chips with the same interface as pyserial. Using this method gives easy access to the additional features on the chip like CBUS GPIO.
This module provides a simple Serial-Like interface to FT232 chips while still allowing access to the CBUS pins for controlling simple signals.
Ctypes is used to interface with either FTDI's d2xx library (when available) or libftdi. In this way this package works on both Windows and Linux (and other libftdi supported OS's) without needing to mess with the FTDI drivers on windows.
In contrast, pyftdi is more feature rich and also cross platform but requires special drivers on windows so you can't also use the FTDI chip as a pure COM port.
import ft232 serial_number = "FT1234" try: sp = ft232.Ft232(serial_number, baudrate=115200) except ft232.Ft232Exception: print("Unable to open the ftdi device: %s" % serial_number) sys.exit(1) #You may use sp as you would a Serial object sp.write(b"Hello World!\n") resp = sp.read(100) #If you want to use the CBUS pins, you enable them with cbus_setup # 'mask' is a bitmask which specifies which pins to enable # 'init' is a bitmask for the initial value for each pin sp.cbus_setup(mask=3, init=3) #Change the current value of all setup pins sp.cbus_write(2) #Print the current value of all setup pins print("CBUS: %s" % sp.cbus_read())
