pyftd2xx

pyftd2xx is a simple python wrapper around the official d2xx FTDI driver libraries. In order for this python module to work you need this driver to be installed and working.

Version 0.95 is the first release and compatible with Python 3. Next Versions will have more docstrings and more functions available. EEPROM functions are planned after release 1.0. Also Linux and MAC OS support is planned to be beyond 1.0 release.

Usage

This module is not really ment to be used on its own as it only provides bare functions. A documentation is available from FTDI here. Those C functions are wrapped in a pythonic way, so that one does not need to mess around with pointers amd references. The naming of function and parameters should match with the documentation, although that violates PEP 8.

Example

So instead of doing the 'C-Style', with declaring each variable in advance and let the function change them, one can just call it and get all the results as a Munch.

C way to do it:

FT_STATUS ftStatus;
FT_HANDLE ftHandleTemp;
DWORD numDevs;
DWORD Flags;
DWORD ID;
DWORD Type;
DWORD LocId;
char SerialNumber[16];
char Description[64];

ftStatus = FT_GetDeviceInfoDetail(0, &Flags, &Type, &ID, &LocId, SerialNumber,
Description, &ftHandleTemp);

Python way to do it:

import pyftd2xx as ft

ft.createDeviceInfoList()
result = ft.getDeviceInfoDetail(Index=0)
print(result)   #{'Flags': ['FLAGS_OPENED', 'FLAGS_HISPEED'], 'Type': 'FT_DEVICE_2232H', 'ID': 67330064, 'LocId': 401, 'SerialNumber': 'A', 'Description': 'Dual RS232-HS A', 'Handle': c_void_p(None)})

This is a heavily changed fork from Satya Mishra which probably is more stable than mine. So make sure to give some credit.
