GENERAL DESCRIPTION
The DLP-2232PB 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 FT2232D when TXE# is low by placing the data byte on the bus and
toggling the WR pin low and then high. If the FT2232D’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 FT2232D will take RXF# low to let the
microcontroller know that at least one byte of data is available. The microcontroller then reads
the data via the RD# pin until RXF# goes high indicating that no more data is available to read.
The current data byte is present on the data bus so long as the RD# pin is held low. When RD#
is returned high, the next byte (if any) is prepared 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 FT2232D 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.
FIRMWARE UPLOAD APPLICATION
As mentioned above, the DLP-2232PB is shipped with its microcontroller pre-programmed with
firmware for basic port pin input/output capability including access to the A/D, EEPROM, and
external digital temperature sensors. However, if required, the Flash program memory can be
erased and reprogrammed with user supplied hex code using a firmware upload application that
can be downloaded from the DLP-2232PB product page at www.dlpdesign.com. Firmware can
also be reprogrammed into the Flash program memory via a 5-pin header and user-supplied
compatible programmer.
*** Note that Channel A is used exclusively for updating the Flash program memory of the PIC
16F877A and channel B is used to communicate with the PIC at run-time. Additionally, using
Channel A for firmware upload requires the DLL drivers to be selected for Channel A in the
EEPROM setup. This is the default setup for the DLP-2232PB from the factory.
