DRIVER SOFTWARE
FTDI’s VCP (Virtual COM Port) driver executable files are provided royalty-free on the condition that they are only
used with designs incorporating an FTDI device (ie the FT245BM and DLP-USB245M). The latest version of the
drivers can be downloaded from dlpdesign.com or ftdichip.com.
The VCP driver download file is a combined set of drivers for Windows ‘98, Windows ME and Windows 2000/XP.
Unzip the file to a blank floppy disk or folder on your PC. The drivers can co-exist on the same floppy disk or folder
since the INF files determine which set of drivers to load for each operating system version. Once loaded, the VCP
drivers allow your application software, running on the host PC, to communicate with the DLP-USB245M as though it
were connected to a COM (RS-232) port.
In addition to VCP drivers, FTDI’s “D2XX Direct Drivers” for Windows offer an alternative solution to the VCP drivers
that allows application software to interface with the FT245BM device using a DLL instead of a Virtual Com Port. The
architecture of the D2XX drivers consists of a Windows WDM driver that communicates with the FT245BM device via
the Windows USB Stack and a DLL that interfaces the Application Software (written in VC++, C++ Builder, Delphi,
VB etc...) to the WDM driver. An INF installation file, uninstaller program and D2XX programmers guide complete the
package
The D2XX Direct Drivers add support for simultaneous access and control of multiple FT245BM devices. The
Extended Open function (FT_OpenEx ) allows the device to be opened either by it’s Product Description or by Serial
Number, both of which can be programmed to be unique. The List Devices function (FT-ListDevices) allows the
application software to determine which devices are currently available for use, again by product description or by
serial number.
Several new features have been recently added to the D2XX drivers. Functions are provided to program the
EEPROM (FT_EE_Program), and read the EEPROM (FT_EE_Read). Unused space in the EEPROM is called the
User Area (EEUA), and functions are provided to access the EEUA. FT_EE_UASize gets its size, FT_EE_UAWrite
writes data into it, and FT_EE_UARead is used to read its contents.
Download FTDI Application Notes AN232-03, AN232-05, AN232-06, and AN232-07 for detailed instructions on how to
install and remove the drivers.
