This integrated board can be controlled through a microcontroller and can be digitally programmed using Direct Digital Synthesis Technology DSS. It operates at a very low power supply, thus finding applications in many small self-assembly projects to produce square and sine waves. The pin configuration, features, interfacing, and applications will also be discussed here.

Crystal Oscillator: The module contains a crystal oscillator to provide clock and timing control for the Integrated Circuit. AD IC: This integrated circuitry does all the processing. With the help of a powerful Oscillator and other components, it can output analog signal waves.

The pin configuration detail in tabular is mentioned below:. The schematic of the module is provided to understand the connections which may turn helpful while repairing the module:. It can be connected to any microcontroller. To install library, open Arduino IDE. After that type AD in search bar.

You will get these options as shown in the picture. Compile the Arduino code and upload it to Arduino. This can be observed visually through the Oscilloscope. It shows us the physical dimensions required when a PCB card is designed.

All so far so simple, pretty much the same as you'd see with AD drivers. The output frequency is set by calculating a bit turning word and loading it to the DDS, either via a 3-wire serial bus or an 8-bit parallel bus. The bit word is comprised of bits of phase and frequency information and a further 8-bit, 3-bits that set specific operating and factory test modes of the DDS - it is these 3-bits that cause problems when trying to use AD code with the AD and 5-bits of phase information.

For simplicity, I set all of these bits to 0. The datasheet gives the following equation to calculate the turning word. In theory, integer maths should be slightly faster and more accurate as the required frequency increases, in practice I find either method fast enough and accurate enough up to 30MHz, frequency errors are due to the poor stability of the reference oscillator on the DDS module.

Calculating the turning word and writing it to the DDS module can them be wrapped up in a single function taking the required frequency as its sole parameter.

Black Entertainment Television (BET) is an American basic cable and satellite television channel that is owned by the BET Networks division of Viacom.

After stepping down as a lobbyist for the cable industry, Freeport, Illinois native Robert L. Johnson decided to launch his own cable television network. Gordon later hosted other programs and specials on BET, such as Black Men Speak Out: The Aftermath, related to the 1992 Los Angeles riots, and a recurring interview show, Conversations with Ed Gordon. In 1991, the network became the first black-controlled TV company to be listed on the New York Stock Exchange.

In 2005, Johnson retired from the network, turning over his titles of president and chief executive officer to former BET vice president Debra L. By 2007, the network had launched two more music-oriented networks, BET Hip-Hop and BET Gospel.

BET also launched a batch of original programming by this time, including reality shows Baldwin Hills and Hell Date, competition show Sunday Best, and town hall-style discussion show Hip Hop vs.

He was then replaced by Stephen Hill, who is also executive vice president of music programming and talent. In the wake of this news, Connie Orlando, SVP Specials, Music Programming, and News, served as the interim Head of Programming, according to chairman and CEO Debra Lee.

Original programming currently seen on BET include Real Husbands of Hollywood, and Being Mary Jane. In addition, the channel broadcasts acquired television series, primarily in the form of sitcoms (such as The Parkers, Family Matters and Moesha), drama series (such as Scandal), and same-day or week-delayed late-night runs of syndicated talk shows (namely The Wendy Williams Show, The Real, and Dish Nation).

Feature films released theatrically and on home video are also aired on the channel, comprising much of its primetime and weekend schedule.

The BET Walk of Fame Awards were established in 1995 by BET. In 2004, proceeds were shared between United Negro College Fund (UNCF) and the BET Foundation, which executes the Healthy BET obesity awareness campaign and other pro-social causes like the annual charitable black-tie BET Walk of Fame ceremony. The awards are presented annually and broadcast live on BET. Global promotion is provided by Kroszover Entertainment. The BET Honors were established in 2008 by the network to honor the lives and achievements of African-American luminaries.

The awards are presented annually and broadcast on BET during Black History Month each February. BET UK first transmitted on Videotron (now known as Virgin Media) and several other cable providers from 1993 until 1996. BET International is the first international version of the channel and is available in Europe, Africa and the Middle East through satellite providers.

BET launched on February 27, 2008 on Sky channel 191 and began to be carried by Freesat channel 140 on August 8, 2008.

BET International shows a mix of content from the main BET channel and locally produced shows. An exclusive, but temporary, HD version of the channel was made to show the 2009 BET Awards on Freesat EPG 142.
