GENERAL DESCRIPTION
The DLP-245PB-G provides a cost-effective, microcontroller-based method of interfacing an
electronic peripheral to a host computer via USB.
To send data from the peripheral to the host computer, the microcontroller simply writes the
byte-wide data into the FT245RL when TXE# is low. If the FT245RL’s transmit buffer fills up or is
busy storing the previously written byte, it will take its 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 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 http://www.dlpdesign.com.
DRIVER SOFTWARE
FTDI's VCP (virtual COM port) driver-executable 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-245PB-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-245PB-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-245PB-G using a DLL
instead of a virtual com port. The architecture of the D2XX drivers consists of a Windows WDM
