Embedded C Programming Compilers For 8051 Microcontroller

robot-sunset

Todays sophisticated computers are developed as embedded systems so that they can be complimentarily used in mobile devices and electronic appliances. The microcontroller turns out to be the key element in an embedded system. Actually a microcontroller is a microprocessor giving more emphasis on the input & output operations. It controls the operation of electronic devices by giving them access to communication, measurements and switching information. Thus a microcontroller is regarded as a device controller. Intels 8051 microcontroller is among the oldest members of the microcontroller family, yet is very popular among users. Technical analysts attribute its popularity to its amazing architecture. Some of the reputed computer manufacturers like NXP, Silicon Labs & Atmel are still using 8051 microcontroller as the basis of their microcontrollers.

The 8051 microcontroller has a complicated memory structure that requires special software instructions to access it segment wise. Therefore special kind of compliers needs to be designed to make the memory accessible. Since the 8051 microcontroller is widely used in IT industry & many projects as well, companies have created their own 8051 microcontroller compatible compilers. As a result various kinds of embedded C programming compilers for 8051 microcontrollers are available in the market. Most of them are offered as part of a package along with debugger, simulator & integrated development environment (IDE). The Keil IDE/compiler is one such popular variety. Similarly SDCC (Small Device C Compiler) is a free & popular compiler that is found compatible with Zilog Z80, Motorola 68HC08, Maxim 80DS390 & Intel 8051 microcontrollers. The open source software code of SDCC is distributed under the guidelines of GNU General Public License.

Though pascal language is rarely used in embedded C programming, a few special Pascal compliers are available for the 8051 microcontroller. The Turbo51 & KSC Pascal51 are good examples of commercial Pascal compilers. Turbo51 is a free complier based on fast single pass & advanced multi-pass optimizing technology & using syntax of Borland Turbo Pascal 7.

While there are not enough options in basic or Pascal compilers, the C compilers are available in abundance. Users are facing difficulty in finding good quality basic or Pascal compilers for 8051 programming. The chief function of the compilers is the code they produce which should be optimized well to enhance the speed & size. However it is not the programming language in compilers which decide the size of the program codes for achieving specific tasks in 8051 programming. Either Pascal or C can be used to generate an optimized & compact code. It is the programmers preference on which platform he/she will feel comfortable working in.

Are You Suffering From Computer Stress

ZF

Sadly, grandma wouldnt have a remedy for this particular ailment. Computer stress is a relatively new term, which has been coined considering the negative impact the over usage of computer, has on our mental and physical health.

Almost everyone gets stiff shoulder, neck and back while working for long hours in front of the screen. And that is just the physical aspect of computer stress, do you have an unclear memory and find it hard to concentrate after a few minute? Ever got really mad and jabbed keys on the keyboard just because your screen wouldnt load fast?

Our incessantly increasing dependency on technology in general and computers in particular, has made it to be a huge part of our lives today. This is why sometime losing data through hard disk crashing or even slow internet connection can take a toll on our stress level and create a feeling of frustration and anger inside us.

Some common symptoms of Computer Stress:
Dry eyes, redness and irritation
Persisting headache
Fatigue and tiredness
Stiff shoulder and neck
Regular back ache
Pain in arm and wrist
Irritability
Absent mindedness
Lack of concentration

A lot of us professionally depend a lot on technology, whether it is storing data or communication. Shutdown or data wipeout is bound to affect out professional life and our physical and mental health. Heres what you can do to prevent and combat computer stress:

Figure out your problems- Is it your data you are most worried about or your internet connection conking off? Figure out what can cause you maximum computer stress and try to look for alternatives. Get a backup of your data in a pen drive and keep a dongle or charm your neighbor to give you their wifi password so that you can use them in times of emergency.

Befriend some tech nerds- If you are anything like me and are truly baffled by the nuances of technology; befriend someone who is good at it. Having a friend or a colleague who can guide you through difficult situations will help in getting solutions to problems in a short span.

Buy decent products- No, you need not go running out and buy a Macbook Pro (although, theres no guarantee of it running flawlessly), but always try to get branded products that would put up. A lot of us compromise on quality to get products cheaper, instead of buying inferior quality goods, see if you can get a deal or a discount.

Relax- We know that things can get difficult and frustrating, but try to keep your calm. Stressing out would only make matters worse, try to look for alternatives and relax.

Organize your work station- Ensure that your computer desk and chair are angled properly or if you work on a laptop, use a laptop table so that you do not slouch while working.

Take breaks in between, stretch yourself and splash some water on your face and especially in your eyes.

General Concepts about Object-Oriented Programming

W

The programming style that we usually call object-oriented programming (OOP) has appeared relatively recently in the history of programming languages. This is a particular and very convenient style for many situations. It was designed to overcome the limits of structured programming based mainly on the widespread use of procedures, functions, pointers or other more or less developed data types.

Although structured programming is very practical for small software systems or reduced non-graphic applications, it should be avoided when dealing with large applications that use graphic elements where object-oriented programming is recommended. Object orientation means organizing software resources as a collection of distinct and discrete objects, which includes both data structures and their processing functions. This organization is an extension of structured programming in which the data structures and processing functions are only loosely connected. All items have their own identity and are perfectly distinct.

An object is defined as an abstract concept, a specific and useful element for any application. Objects serve two specific purposes:

– they provide a better understanding of the problem to be solved;

– they provide a base design for implementation.

A class of objects encapsulates a certain number of objects with similar properties. This similarity refers to both the description (data and attributes) and the behavior (functions or methods). Attributes are unique features within an object class. Each attribute receives a certain value which can be modified during the objects life cycle. Two or more objects can have the same or different values for the same attribute.

Methods or operations are processing functions applied to objects of a certain class. All objects within a class admit the same set of methods, methods which in return may receive any number of additional parameters. In order to apply various methods to an object, it has to be created (defined). Defining an object is called instantiation. Once an object has fulfilled its mission it is removed.

Abstraction is a fundamental human trait that allows us to build models and thus cope with complexity. In every field of human activity, project approach is based on building a model for a better understanding of the problem to solve. Software engineering makes no exception. Through abstraction the essential key aspects are isolated from the non-essential ones. Therefore, each problem might have several adequate models.

In the software engineering industry, structured programming has made a big step forward defining three perspectives needed in order to properly address any application. These perspectives, also known as models, are: the static model, the dynamic model and the functional model.

There are currently several object-oriented methodologies used for analysis, design and implementation of software resources. One of these modeling methodology is the OMT (Object Modeling Technique) methodology. This method of modeling involves the planning of the various development stages and a graphical representation of objects and their relationships.

Gm’s Robot Commercial Depicts Suicide According To Nami

robot-sunset

General Motors robot commercial which was aired during the Super Bowl has aroused various reactions from the audience and most of them were not very happy with what they have seen. According to the Mental Health and Suicide Prevention Community the commercial encourages suicide.

After General Motors controversial ad, the company has been bombarded by complaints. But according to the worlds largest automaker and maker of the popular GM Nerf Bars, everything is under control and as a matter of fact – they are also planning to air the same commercial again for the Academy Awards on February 25.

The National Alliance on Mental Illness or NAMI, the nations largest organization that focus on serious mental illnesses, depression and obsessive-compulsive disorders has expressed their disappointment with General Motors through their Executive Director Michael Fitzpatrick, who commented, The GM commercial is recklessly irresponsible. How many national organizations does it take to change their minds?

It should be noted that it was not only the robot commercial of General Motors that was considered offensive during the Super Bowl. Even the ad of Mars, Inc. for its Snickers candy bars has also provoked negative reactions from the crowd especially from the gay community. But unlike GM, Mars, Inc. has decided to stop their Super Bowl ad for fear of further offending the public.

Fitzpatrick explained that the traditional marginalization of mental health concerns is rooted in stigma and discrimination. General Motors robot ad that reportedly suggests suicide may encourage some very depressed individuals to commit suicide. Suicide kills. Depression kills. Obsessive-compulsive disorder can kill. But GM sees those kinds of concerns simply as cute, advertising gimmick. What does it say about the companys concern for public health?

In the ad, the robot that was working for GM drops a bolt on the assembly line and was fired because the automakers obsession for quality. The robot search for other jobs but unfortunately got fired again. Due to extreme depression the robot decides to end his life by jumping off the bridge.

The tragic concept of the ads has alerted NAMI to take the necessary step in informing General Motors of the horrible impact it might have on emotionally disturbed individuals who may see that commercial. NAMI has warned GM that the depictions of suicide in mass media in the past have been proven to increase the risk of suicide contagion, clinical term for copy cat suicides.

NAMI also added that the robot ad may increase suicide cases in the country brought about by the fact that there are a high number of unemployed individuals in the country right now. And unfortunately General Motors with its restructuring program has caused many employees to lose their jobs. The ad will be like adding insult to injury.

Benefits Of Fax Over IP Technology In Small Businesses

P1

Voice over Internet protocol (VoIP) technology has become standard in many offices and storefronts. It provides higher bandwidth and better capabilities than traditional phone lines. Faxing has changed because of the introduction of VoIP technology. Traditional fax machines that used modulated sound to transmit data are being replaced by software-based digital systems. Small businesses can benefit in a number of ways by switching to fax over IP technology.

Reliability

One of the ways fax over IP can help a small business is by improving the reliability of transmissions. Traditional faxes rely on signal modulation to send and receive data. Inconsistencies in the telephone lines, minor hardware issues and even different fax machines can cause these transmissions to fail or to become corrupted. The fax over IP technology is digital and the data has a very low to non-existent chance of loss. This makes digital faxes far more reliable.

Lower Costs

Fax over VoIP will save small businesses money over traditional faxing technologies. VoIP protocols can be sent across any network line. They can also be interpreted by a wide range of technologies from computers to multifunction printers and even mobile devices. This makes it unnecessary to maintain dedicated phone lines. It also decouples faxing from older fax machines that require constant maintenance, paper and toner.

Environmentally Friendly

Sending fax over VOIP in a network through a line can be done completely electronically. Small businesses do not need to feed a paper printout of an invoice or report into a machine. Similarly, faxes that have been received do not need to be printed immediately or at all. Sending and receiving faxes can be done through a software interface. Faxes can be sent and received as digital files that are viewed on computer screens or mobile devices. This allows a small business to be more environmentally friendly without having to sacrifice the convenience of faxing.

Better Access for Employees

The traditional way of sending faxes involved loading a machine, dialing a number and then waiting for a confirmation. This is time consuming and inefficient especially when multiple people need to send a fax. Fax over IP technology makes it possible for employees to send faxes seamlessly from a desktop or other device. The fax can be added as a network device similar to a printer. Employees can simply send documents to the fax from within different programs.

Higher Quality Faxes

A large benefit for modern businesses is higher quality faxes. Fax over IP can encode documents created digitally. There are no scanning or resolution issues. People who receive the fax will see the document exactly as it was created. This can make it easier to send documents that include detailed charts, small graphics or complex illustrations. The individual pixel will not run together and become illegible because of issues with an optical scanner at the last minute.

Current Science Article Stem Cell Research in the Spotlight Once Again

SS

Recent discoveries about the role of stem cells in cancer have altered the landscape of cancer research, says Medical News Today. There is, however, a long-running philosophical rift over stem cell research at both the state and federal levels. Some groups would rather focus on adult stem cell research, avoiding the moral and ethical questions about research involving embryos. While ethical debate on human embryonic stem cells will continue, much more is occurring on the rings surrounding this bull’s-eye issue, including research in both drug development and adult stem cells.

Biologists’ understanding of new sources and uses of adult and nonembryonic stem cells is advancing rapidly. Called “niches” or “crypts,” it seems that almost anyplace one looks in the body (nose, eye, hair follicle, intestine, bone marrow, central nervous system), stem cells are being found. From such basic knowledge, it has been reported that successful animal and human therapy using patient stem cells is already occurring. As more stem cell crypts are discovered, the desire to understand how to manipulate them within the body only becomes more acute.

At the 2007 Annual Meeting of the American Association for Cancer Research, researchers presented new discoveries about stem cells in leukemia, breast and colon cancer that add to the growing evidence that perhaps cancer is, fundamentally, a stem cell problem.

Interviewed by Vision Magazine at the Stem Cells World Congress earlier this year in La Jolla, California, veterinarian and CEO of Vet-Stem, Robert Harmon, explained how his company is currently providing stem cell therapies for animals. Injected into an injury or degenerated tissue, the stem cell treatment evokes healing in unprecedented ways. As it has been since its discovery almost 400 years ago, the cell and the “vital force” that makes it the seat of biological life continues to hold attention. It is likely that there will be no end to the moral and ethical questions and investigations. Today’s new age of molecular understanding, genomics, proteomics, gene splicing and bioengineering is barely underway. It is not surprising, then, that the more we know, the more we recognize how little we understand.

The timeline of discovery has been exponential: from discovery of the DNA double helix in 1953, and the understanding of the genetic code, gene splicing and cell differentiation in the 60s, 70s and 80s, science rapidly jumped up the learning curve to the cloning of whole organisms and the discovery of embryonic stem cells less than a decade ago. The future possibilities for the application of this knowledge seem enormous.
