The Serial Peripheral Interphase - 533 Words

The Serial Peripheral Interface (SPI) is a synchronous bi-directional (full duplex) serial data protocol used by microcontrollers to enable communication between one or more peripheral devices that are all of short distances to one another. Furthermore, it can also be used for communication between two microcontrollers; with particular interest between Arduino boards and Multiwii flight controllers. In general, an SPI data link consists of one master; typically a microcontroller which controls one or more peripheral devices known as slaves. Both the master and the slaves share three common lines which include; MISO (Master In Slave Out) which is responsible for transferring data from the slave to the master; MOSI (Master Out Slave In) which is responsible for transferring data from the master to the slaves; and SCK (Serial Clock) which is created by the master and is responsible for synchronising the transmission of data between master and slave in respect clock pulses. There is also SS (Slave Select) line that is specific to a pin on each slave device and in which the master can use to enable and disable specific slave devices. In the case a slave devices SS pin is low, communication is enabled with the master. However in the case it is high, communication is disabled with the master. This allows multiple devices using SPI to share common MISO, MOSI, and CLK lines. Full duplex data transmission occurs during each clock cycle generated by the master in which the masterShow MoreRelatedProject Managment Case Studies214937 Words   |  860 PagesDivision, which manufactures disk drives, the Lampco Division, which is responsible for Department of Defense (DoD) contracts such as for military application, satellites, and so on, and the Ridge Division, which is the primary research center for peripherals and terminals. CONTINENTAL COMPUTER CORPORATION According to Ed White: Our major problems first began to surface during the early nineties.

Journalism Developments and Debates

Question: Discuss about theJournalismfor Developments and Debates. Answer: Reason for Wanting to Study Journalism Since a long time, I have been cherishing the dream of studying journalism. In todays world, journalism is a dynamic profession. It is not because I will be able to travel various places while collecting news, but because it will allow me to understand the world and the humans. I always had a knack for collecting news and writing it down. However, I want to study the subject to learn professional skills, and theories and practices of journalism from past to the present. As a subject journalism covers a lot of areas. Starting from politics, art and literature, cinema, television, to international relationship, business, science, economics; journalistic writing is applied in all these sectors. After completion of my course, I will be able to choose the area I wish to write about and then explore it with my own capability. Journalism, as a profession, is gaining not only popularity but validity with time. People are hungry for news. They want to know in detail what is happening around the world. They want to know all interesting news. It is the responsibility of the journalists to aware them about every situation. Journalists are bound to find all interesting news and cater them to the public. Even in some cases, their presentation makes the story interesting. I am willing to know how they work and what they focus on. It s also seen how journalism as a profession have undergone changes with the advent of digitization. Now we avail news from internet. Various social media websites are working as a communication platform for the journalists. After doing my course, I will be able to explore my profession with the help of technology. Understanding of Changes in Contemporary Media and the Impact on Journalism In an age of globalization, media has undergone a complete change. Starting from the communication platform to the type of news catered to the public, journalism as profession has become a more dynamic one. Newspaper, radio and television were the main communication media. However, with the technological explosion and development of internet, media has started using these platforms as well. Nielsen et al (2013) opined, Digitization has made the communication easy. It is a fact that we want to get the news as fast as possible. According to Neumayer (2013), in earlier days, newspaper was the only medium. One had to wait for the next day to get the news of the previous day. Then television and radio came. It made the availability of news faster than newspaper. However, these media platforms started become old when internet established itself as the fastest of all. As discussed by Franklin (2012), now, people dont have to wait at all. Every incident of every single moment is catered to people through internet. Such changes have made journalism more challenging than before. With the explosion of news, now we dont want to wait. Even, people do not waste their energy much on same news story because of the availability of bunch of news stories within a short period. Therefore, news stories are having less longevity. Neveu (2016) discussed, it is estimated that between 2007 and 2015, CNN has edited their news packages into half of their original length . It is the challenge of the journalists to make every news story interesting. Otherwise, it will not sustain. Sometimes, it has resulting into yellow journalism which is not acceptable. Kammer (2013) explained that as a negative impact, the journalists serve invalid and not so valuable news stories in some cases to retain public interest. Sometimes, it crosses the limits of libel. However, journalism is not a profession where the journalists can write anything that happens. It is about making the authentic and accurate story and serving it to those who need them. To talk about positive impact of journalism, it is needless to say that it has given birth to personal blogs and websites in large numbers. The aspiring writers are enjoying the freedom of speech. According to Picard (2014), the bloggers do not belong to any specific media banner. Therefore, they are able to exercise their own point of view through blog writing. They are true to their own emotional outcomes and do not depend on any media house. Surely, the profession is earning them both money and job satisfaction. The readers are also exercising their choices. They are given thousands of stories from which they select the ones they prefer to read. Surely the change has made journalism a challenging profession.
