storing the previously written byte, it will take TXE# high in order to stop further data from being

written until some of the FIFO data has been transferred over USB to the host.

When the host sends data to the peripheral over USB, the FT2232H will take RXF# low to let the

microcontroller know that at least one byte of data is available. The microcontroller then reads the

data until RXF# goes high indicating that no more data is available to be read.

By using FTDI’s Virtual COM Port Drivers, the peripheral looks like a standard COM port to the

application software. Commands to set the baud rate are ignored--the FT2232H always transfers data

at its fastest rate regardless of the application’s baud-rate setting. The latest versions of the drivers

they are used only with designs incorporating an FTDI device (i.e. the FT2232H on the

DLP-2232MSP). The latest version of the drivers can be downloaded from www.dlpdesign.com or

www.ftdichip.com.

The VCP driver download file is a combined set of drivers for Windows 7, Windows Vista and

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 the application software running on

your host PC to communicate with the DLP-2232MSP as though it were connected to a COM

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 FT2232H

devices. The extended open function (FT_OpenEx) allows the device to be opened by either 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.

identifiers, the manufacturer's product string or a serial number.

MPROG is an EEPROM serializer and testing utility from FTDI for the FT2232H device. MPROG is

based on the new D2XX drivers and will work on Windows 7, Windows Vista and Windows 2000/XP

platforms. You must install the latest release of the CDM drivers in order to run this application. (Refer

to the MPROG User’s Guide for details on the program’s use.)
