The DLP-USB1 provides an easy cost-effective method of transferring data
to / from a peripheral and a host at up to 8 Million bits (1 Megabyte)
per second. It’s simple FIFO-like design makes it easy to
interface to any microcontroller or microprocessor via IO ports.
To send data from the peripheral to the host computer simply write the
byte wide data into the module when TXE# is low. If the (384 byte)
transmit buffer fills up or is busy storing the previously written byte,
the device takes 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 device will
take RXF# low to let the peripheral know that data is available.
The peripheral then reads the data until RXF# goes high indicating 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 device always transfers data at it’s fastest
rate regardless of the application’s baud rate setting. The latest
versions of the drivers are available for download from
FTDI's Drivers page.
