Welcome to the FTD2XX Programmer's Guide41 Welcome to the FTD2XX Programmer's GuideFTDIs "D2XX Direct Drivers" for Windows offer analternative solution to our VCP drivers which allowsapplication software to interface with FT232R USBUART, FT245R USB FIFO, FT2232C Dual USBUART/FIFO, FT232BM USB UART, FT245BM USBFIFO, FT8U232AM USB UART and FT8U245AMUSB FIFO devices using a DLL instead of a VirtualCOM Port.The architecture of the D2XX drivers consists of aWindows WDM driver that communicates with thedevice via the Windows USB stack and a DLL whichinterfaces the application software (written in VisualC++, C++ Builder, Delphi, VB etc.) to the WDMdriver. An INF installation file, uninstaller programand D2XX programmers guide complete thepackage.The document is divided into four parts:· Classic Interface Functions 5 which explainsthe original functions with some more recentadditions· EEPROM Interface 53 which allows applicationsoftware to read/program the various fields in theFT232R/FT245R internnal EEPROM or external93C46/93C56/93C66 EEPROM for other devices,including a user defined area which can be usedfor application specific purposes.· Extended API Functions 65 which allow controlof the additional features available from our 2 ndgeneration devices onwards.· FT-Win32 API 72 which is a more sophisticatedalternative to the Classic Interface - our equivalentto the native Win 32 API calls that are used tocontrol a legacy serial port. Using the FT-Win32API, existing Windows legacy Commsapplications can easily be converted to use theD2XX interface simply by replacing the standardWin32 API calls with the equivalent FT-Win32 APIcalls.Please note that the Classic Interface and theFT-Win32 API interface are alternatives.Developers should choose one or the other: the twosets of functions should not be mixed.Main Differences Between Windows andWindows CE D2XX Drivers· Location IDs are not supported by Windows CE· FT_ResetPort and FT_CyclePort are not available· Windows CE does not support overlapped IO for© Future Technology Devices International Ltd. 2005
