GENERAL DESCRIPTION
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.
