Universal Serial Bus (USB) is a communications architecture that gives a personal
computer (PC) the ability to interconnect a variety of devices using a simple four-
wire CABLE. The USB is actually a two-wire serial communication link that runs at
either 1.5 or 12 megabits per second (mbs). USB protocols can configure devices
at startup or when they are plugged in at run time. These devices are broken into
various device classes. Each device class defines the common behavior and
protocols for devices that serve similar functions. Some examples of USB device
classes are shown in the following table
As mentioned, most computers include a serial port. The only hardware setup required is connecting the serial CABLE to the serial port on the PC and the serial port on the instrument. The serial instrument may include some hardware drivers or software utilities for communication, and should include documentation on the baud rate, packet size, stop bits, and parity bits that the instrument will use. Additionally, check the National Instruments Instrument Driver Network to see if LabVIEW drivers already exist for yout instrument, as
This designs demonstrates how to use the Ethernet port using a Nios II system on the DE2 board. It sends packets, and using a loopback Ethernet CABLE, it ll receive the same packets which are then displayed. It also works if the board is connected to another packet source.
A few short years ago, the applications for
video were somewhat confined—analog was
used for broadcast and CABLE television, VCRs,
set-top boxes, televisions and camcorders.
Since then, there has been a tremendous and
rapid conversion to digital video, mostly based
on the MPEG-2 video compression standard.
Today, in addition to the legacy DV,
MPEG-1 and MPEG-2 audio and video com-
pression standards, there are three new high-
performance video compression standards.
These new video codecs offer much higher
video compression for a given level of video
quality.
This example program is the source code for the FT232BM Test Application from our Utilities page.
It can be used to test the handshaking lines on FT232BM based RS232/RS485/RS422 designs. This program can also be used for programming the external EEPROM over USB in a manufacturing environment. The test features require the test CABLE shown on ST_232_245.pdf to be connected.
Our D2XX direct drivers should be installed for this application. The code can be modified to fit your requirements.

Data logger Serial Communication function based on new Renesus microcontroller. This module has been tested on the renesus develop board with RS232 CABLE.
The objective of this project is to create a driver for a camera module (we used the OV7620). After taking the image with the camera, the driver will store into the external asynchronous RAM, and then send it to the computer through a serial CABLE
The STi7105 uses state of the art process
technology to provide an ultra low-cost, fully
featured HD AVC decoder IC. It is a highly
integrated system-on-chip suitable for STB markets across all networks (CABLE/satellite/DTT/x-
DSL/IP) worldwide
The STi7141 is a highly integrated SoC (systemon-
