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 Programmer’s 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 its
product description or 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.
EEPROM WRITE UTILITY
The DLP-245SY has the option to accept manufacturer-specific information that is written into the
on-board 93C46 EEPROM. Parameters that can be programmed include the VID and the PID
identifiers, the manufacturer's product string, and a serial number.
FTD2XXST is the latest EEPROM serializer and testing utility from FTDI for the FT245BM device.
It replaces the VCP-based 232Prog utility. FTD2XXST is based on the new D2XX drivers and will
work on Windows 98, Windows ME, and Windows 2000/XP platforms. You must install the latest
release of the D2XX drivers in order to run this application. (Refer to the SER200.PDF guide that
is included in the EEPROM write utility’s download zip file for details on how to use the serializer.)
The DLP Design Test Application V2.0, available from DLP Design as a separate purchase, can
also be used to program the DLP-245SY’s EEPROM with manufacturer-specific strings. For
