When the host sends data to the peripheral over USB, the FT245RL 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 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 FT245RL always transfers
data at its fastest rate regardless of the application’s baud-rate setting. The latest versions of the
drivers are available for download from DLP Design’s website at www.dlpdesign.com.
DRIVER SOFTWARE
FTDI's VCP (Virtual COM Port) driver files are provided royalty free on the condition that they are
used only with designs incorporating an FTDI device (i.e. the FT245RL and
DLP-245PL-G). 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
coexist 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-245PL-G 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 allow application software to interface with the DLP-245PL-G 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 FT245RL 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 FT245RL
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.
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.
