AYODEJI4LOVE: pls don't abandon this thread o.....thanks for the video.........just started with my own training on embedded system....using c ...pls i will need your help
when struck .......and advice......

There is a thread titled 'Microcontrollers' by hoodboi. It has enough C tutorials. The compiler used was CCS with pic microcontrollers. Search for it inside nairaland.

pricelessmr:
Yes, we can. I strongly believe we are better than most Chinese and Indians. I would need your collaboration. What do you think?

Nice project, u can IM me.

pricelessmr:

Nice.

That reminds me, I have a flexible moving message (LED Dotmatrix ) display that takes alpanumeric input from an infra-red remote control (simple and readily available tv remote) to update information for display, meaning, you can Change the displayed message on the fly without reprogramming the chip. It uses simple PIC microcontroller. I think I have a video of its operation on my desktop.

It was amazing how stress-free and flexible it was for students, hobbyists and some guys who build dotmatrix display for clients to assemble a customized display.


It's unprofessional to hard-code the message in the chip by knowing before hand what clients want to display and reprogramming the chip just to change the displayed message.

TV remote ?? Can you get all english alphabets (A - Z) from tv remote. I think the best option is sms based dot matrix using gsm modem

Sorry C#/vb.net is not for microcontrollers.

Assembly language is good but C language is best

In 2013 we have seen a dramatic increase in the number of hack attacks attempted against banks, credit unions and utility companies using various techniques including DDoS attack, SQL injection, DNS Hijacking and Zero-Day Flaws.

SQL Injection is one of the most common security vulnerabilities on the web and is successful only when the web application is not sufficiently secured.

Recently a hacking Group named 'TeamBerserk' claimed on Twitter that, they have stolen $100,000 by leveraging user names and passwords taken from a California ISP Sebastian (Sebastiancorp.com)to access victims' bank accounts.

A video proof was uploaded on the Internet, shows that how hackers used a SQL injection attack against the California ISP Sebastian to access their customers' database includes e-mail addresses, user names and clear text passwords and then using the same data to steal money from those customers.

Let's see what SQL Injection is and how serious an attack like this actually can be.

SQL Injection is a type of web application vulnerability in which the attacker adds Structured Query Language (SQL) code to web inputs to gain access to an organization's resources. Using this technique, hackers can determine the structure and location of key databases and can download the database or compromise the database server.

Hackers took just 15 minutes to hack into the website using SQLmap (Automated SQL Injection Tool) -- stole customers' database and then immediately accesses the victim's Gmail account, linked PayPal accounts and Bank accounts also.

It's so hard to remember multiple passwords, some people just use the same one over and over. Is your Facebook password the same as your Twitter password? How about the password for your bank's website?

Now the hack explains that this us why it's extremely dangerous to use the same password on more than one Web site. In the POC video, hacker randomly chooses one Sebastian username and his relative password against Paypal, Gmail and even Citibank account logins and seriously that actually worked, because the victim is using the same passwords for all websites.

Now that you've control of the situation, don't let this happen again! If you have a bank account, a few credit cards, and several other important sensitive accounts, conduct a thorough security audit on them. Be sure that you know when you last logged in. Be sure to keep using different and Strong passwords for each website.

A California man this week filed a lawsuit against Apple CEO Tim Cook claiming the company installed its iOS 7 software on his family's iDevices without permission.

The plaintiff, Mark Menacher of Poway, Calif., filed the complaint Thursday with the Superior Court of California in San Diego. Menacher said he is seeking the "removal of iOS7 downloads from his family's iDevices and reimbursement of ancillary costs totaling $50."

Apple did not immediately respond to a request for comment.

"Apple's disregard for customer preferences in relation to iOS7 is corporate thuggery," Menacher said. "Steve Jobs was reportedly rough on company employees in pursuit of happy customers, but Tim Cook apparently cultivates a culture of contempt for customer satisfaction in pursuit of corporate profits. It is a policy that will eventually fail."

Menacher filed the suit with the court's small claims division and is representing himself in the matter, though he told PCMag that he informed Apple's chief counsel Bruce Sewell earlier this month that his plan was to "start in the small claims court and work up."

The plaintiff said he had made numerous requests to remove the software from his devices directed at Apple's technical support staff, executives, and board of directors, "all to no avail."

In a copy of the complaint sent to PCMag, Menacher claims: "Unsolicited and undesired, the Defendant has downloaded software to several iDevices. This represents fraud, trespass, and theft. Plaintiff seeks removal of software download and restitution for time and expenses pursuing such."

He goes on to say that similar complaints about the installation of iO7 on consumers' iDevices "abound in the technological media and on Internet forums."

A trial date has been set by the court for Jan. 28, 2014.

Microsoft’s too bloated to innovate. Busting it up into specialized companies would solve that problem nicely.

Boss man: Steve Ballmer said he intended to step down as Microsoft’s CEO.

Microsoft missed a golden opportunity when it settled its anti-trust case with the U.S. Department of Justice on November 2, 2001. The government had proved in court that Microsoft was a monopoly and had illegally “tied” the distribution of its Web browser Internet Explorer to Windows, but the court’s chosen remedy—breaking Microsoft into two companies—was thrown out on appeal.

It turned out the trial judge had given secret interviews to the media and publicly disparaged Microsoft officials outside the courtroom. And by then, the Bush administration had taken office and was not interested in breaking up a major U.S. corporation. Then the 9/11 attacks gave us new enemies to worry about. Microsoft got off with a slap on the wrist.

Today’s Microsoft is a behemoth. Apple may be making more money, but Microsoft is doing more things—from writing operating systems and applications, creating software for corporate servers, running cloud-based services for customers, developing hardware, and sinking billions a year into a still unprofitable Online Services Division, which runs the Bing search engine.

Having built Microsoft into a company that makes the vast majority of its income from catering to business customers, CEO Steve Ballmer announced last week that he is ending his 13-year run as Microsoft’s CEO.

The next CEO should break up the company.

The reasons are quite different from those that led to the U.S. case against Microsoft. That case revolved around the question of whether or not Microsoft could force customers purchasing its Windows operating system to also take a free copy of its Internet Explorer browser. Microsoft insisted the browser was part of the operating system. The government said the browser was independent and selling them together was an anti-competitive practice called “tying.”

What made Microsoft the giant it is wasn’t this tie-in, though. It was more like “lock-in.” Even when the case was being litigated, it was clear that the real source of Microsoft’s monopolistic power was the link between the company’s desktop operating system (Windows), its word processor, spreadsheet and presentation programs (Office), its corporate e-mail and calendar (Exchange), developer tools (Visual Studio), and many other applications

This suite of great programs worked best together, creating a kind of Venus flytrap effect for corporations and governments that fully committed to running Windows everywhere. Microsoft collected billions. By 2003, it had accumulated a $43.4 billion cash surplus. Today it has $77 billion.

But Microsoft also got locked-in—to the easy money that comes from satisfying a captive customer base. The company that had made its fortune by riding the disruptive technology of the personal computer became so focused on keeping those revenues coming in that it stopped being able to execute on the next big thing. Case in point: since Ballmer took over, the number of Internet users relying on Internet Explorer dropped from a high of more than 85 percent to roughly 12 percent today (53 percent use Google’s Chrome and 29 percent use Mozilla’s Firefox).

Microsoft has earned a reputation of hiring some of the brightest people in the industry—but when those people develop breakthrough technology, those products frequently have to be killed so that they do not threaten the company’s cash cows.



One example is Courier, a clever two-screen tablet that 130 Microsoft employees developed between 2008 and 2010. Unlike Apple’s iPad, which is designed for consuming content, Courier was designed for creating it. The tablet would have launched around the same time as the iPad and might have fundamentally changed the way tablet computing evolved, but Microsoft killed the Courier because it was perceived as a threat to some future version of Windows. (Jay Greene wrote a revealing article explaining why Courier was killed, including photos of the tablet and its screens, back in 2011.)

While some Ballmer postmortems pin Microsoft’s downfall to the company’s inability to make that shift to mobile devices, the problems are deeper than that. Kurt Eichenwald’s August 2012 article in Vanity Fair, “Microsoft’s Lost Decade,” places the blame on internal conflicts and bureaucratic paralysis. Microsoft didn’t need innovation so much as a workforce of interchangeable programmers that could fix bugs, address security concerns, respond to customer requests, and bring out a new set of operating systems and applications releases every two or three years in order to force its customers to shell out more cash for upgrades.

To really innovate again, the next CEO of Microsoft should break up the company into parts (what some are calling “Mini Bills”). Here’s my prescription for a few of them:

An operating systems company. It would run Windows and capitalize on the huge ecology of business applications that’s built up around it. For a change, though, this company would open-source the operating system, creating a new version of Open Source Windows that is small, easy to maintain, efficient, and highly securable. Such a system would put Linux on the defensive. The company would derive its revenue from service, support, and consulting.

A desktop applications company, which would maintain and improve those apps that customers around the world rely upon. These apps, like Word, would remain closed source, but they would become operating system agnostic—running equally well on Windows, Mac, Linux, and in the cloud.

A server applications company. This company would be the closest to the Microsoft of today. Maybe it could even keep the name. It would continue to cater to Microsoft’s demanding business customers.

An entertainment spin-off. This one gets XBox, Microsoft’s hardware engineers, and the game designers. What their future holds here is anybody’s guess. Despite huge customer visibility, the annual report makes it clear that this division just isn’t all that profitable.

Finally, Microsoft’s online division will be forced to swim or sink. Microsoft has already realized that it never had any business running a travel agency (Expedia) or a cable news network (MSNBC). It probably doesn’t need to be running a search engine or a consumer e-mail provider either.

Although there is a considerable amount of speculation, and even betting, on who will be the next Microsoft CEO, the job may be an unenviable one for anyone considering the position.

Microsoft is a behemoth that continues to acquire staff and resources as it chases the market transitions that it missed. And in the midst of the company, there are groups constantly at odds over the company's strategy. So, should the board be looking for a turnaround expert or should they be asking a much broader question: What is the best way to structure Microsoft?

After approving the current Microsoft strategy and all the acquisitions the company has engaged in, it is difficult to imagine that the Microsoft board, which includes the two previous CEOs, would consider breaking up the company, but maybe they should. Leading a giant that continues to be outflanked by smaller or more innovative competitors, may be a case in futility.

Microsoft, its partners, and stakeholders may be better suited by a new strategy that considers breaking the company up into pieces that have aligning strategies and expertise. It is much better to consider this now than when market conditions or investor frustration force the scenario. Recent break ups of companies like Motorola and Nokia come to mind. A break up at this time is also a much more attractive option than having to scale down and retrench into tradition segments at a later date.

This would alter the search criteria for the next CEO, or CEOs. Rather than debating between the benefits of a business vs. technical leader or an industry visionary vs. turn-around expert, the board could narrow the criteria for each of the individual pieces of the pie. These leaders may already exist within the company but may be encumbered by the existing politics of the current entity. This strategy could also lead to the divestiture of certain assets altogether.

In the end, whatever remains should be a better competitive position than Microsoft is in today. Adopting such a strategy would still require someone to oversee its execution, but maybe not a high-priced hired gun that may have his or her own objectives and opinions.

Breaking up Microsoft would undoubtedly change the landscape of the electronics industry. But then again, it is already changing and in many ways that are not favorable to Microsoft as it is today.

is this a joke ?

pheforusty: Is it possible 2 combine 2 voltage regulators 78XX to get a current of 2A.

It is possible, but you must add some diodes (D1 and D2) in the link below to protect the regulators.
http://www.instructables.com/id/Increasing-current-on-78xx-series-regulators/

You can also use a pass transistor as show below:
http://electronicsjmbh..com/2012/02/power-supply-5-volts-5-with-pass.html

...... your transformer must be up to 2A (or more)

i've downloaded d book.almost same as pic16f8x datasheet.the formula 4d rc osc frequency wasnt shown.they only recomend values for r&c.is there a formula to cal the frequency?i'v read f=1/RC bt it's nt acurate.it doesnt take temp&voltage into consideratn.i tink microchip intentionaly hid ths info.jst want 2know d speed my uc 's runing

I will advice you to use crystal, forget about the RC. If you can't get 4MHz(or less) crystal then change your chip to Pic16f84a or any that can accept high crystal value.

(~) was used to invert the LEDs connection because the hardware connection was not the same as the font generator

0x7e,0x90,0x90,0x7e,0x00 are hex values that will form the character you want to display on the dot matrix. You can generate the hex values using a "dot matrix font generator" You can download it from here:http://www.instructables.com/id/LED-Scolling-Dot-Matrix-Font-Graphics-Generator-/. It is an excel software

The code bellow will display a still letter A:

#include <16f887.h>
#fuses HS, NOWDT, NOLVP
#use delay(clock = 8MHz)

void clock(){ output_high(PIN_B6);
              output_low(PIN_B6);
            }
            
void reset(){ output_high(PIN_B7);
              output_low(PIN_B7);
            }
            
void display(unsigned char c)
{
    output_D(c);           /* to display 1/5th of letter                                     */
    delay_ms(1);           /* to display the data in a column for 1ms                        */
    output_D(255);         /* to blank the display                                           */
    clock();               /* to give a clock to CD4017 for column multiplexing              */
}
/////////////////////////////////////////
void main()
{
 delay_ms(100);
                                                         
    while(1)
    {
        reset();               /* to jump to first column from right              */
        display(~0x7e);        /* 1/5 portion of letter A                         */
        display(~0x90);        /* 1/5 portion of letter A                         */
        display(~0x90);        /* 1/5 portion of letter A                         */
        display(~0x7e);        /* 1/5 portion of letter A                         */
        display(~0x00);        /* 1/5 portion of letter A                         */
        reset();               /* to jump to first column from right              */
    }
}

The PIC16F887 provides the 8 bit row data. CD4017 is used to select the column one by one. Now, for shifting the column position, a clock is provided by the PIC to the CD4017. On every clock, the column is shifted .(from right to left in this case).

Dot Matrix Scrolling Message Display[size=10pt][/size]

Introduction:

Multiplexed displays are electronic displays where the entire display is not driven at one time. Instead, sub-units of the display (typically, rows or columns for a dot matrix display or individual characters for a character orientated display) are multiplexed, that is, driven one at a time, but the electronics and the persistence of vision combine to make the viewer believe the entire display is continuously active.

10x8 LED dot matrix display:



In the above figure, the rows are negative and columns are positive. Now, if I connect a single column to positive 5V and a single row to negative (0v), then the LED in place of the intersection of the corresponding row and column will glow. Now , if we select a single column(means a +5 volt at selected column) , say column 1 and multiple rows (means connect 0V to few selected rows), say row 1,2 & 8, then the selected 1,2 and 8 LEDs in column 1 will glow. Now if i shift the column(means shifting the positive voltage from column 1 to column 2), and if i change the row data ,then the new data will be displayed in column 2.
Now, if i continuously shift the column and provide row data corresponding to each column, then i can display the different row data (8 bit) in different columns.
. So, if one frame(10 column shift) is completed within 1/16 th of a second, then due to the persistence of vision of our eye, we will feel the entire columns are activated at a time, and thus we will see all the ten -8bit data corresponding to the 10 columns , at a time.
Now, if a set of 8bit data (say 5x8 ) represents a letter, say , 'A' then we will see letter 'A' in the display.

Tchalz: Thanks PrinceJude f0r everything..D0es y0ur c0mpany n0w have Pic16f628A?

We don't have 16f628A but we have 16f84A, 16F873A, 16F876A

hopefullman: @engr princejude.i have sucessfully programed my pic with mplab.i cant forgive myself for forgetting to buy a 4mhz crystal when ordering for my pickit3.i have 8,14,27mhz xtal bt d pic wont run with it.my pic doesn't have internal oscilator{pic16f84a-04/p}.i'm using an external RC oscillator which is very unstable.i had to erase my pic severaltimes to make a code to work.the code isn't working verywell since i dnt knw the frequency d pic is operating.thanks for ur help.

ww1.microchip.com/downloads/en/devicedoc/31002a.pdf‎

Study the above microchip's OSCILLATOR manual.
Read section 2.4 : "External RC Oscillator"

and don't forget to include the reset circuit at "MCLR" pin.
that is, connect 10k resistor from Pin 4(MCLR) to VCC
and 10uF capacitor from Pin4(MCLR) to GND.


But why do you use PIC16F84A-04/P ? That chip is too low and expensive.

The Chairman, Managing Director and the CEO, Peace Group, owner of the Popular Transport Firm, Peace Mass Transit, Mr Samuel Maduka Onyishi, in this interview with ANTHONY ADA ABRAHAM, discusses why he wants to continue to sustain the empowerment programmes and an all-round industrial revolution in Enugu State, this time, as a politician.

Some major entrepreneurs would rather focus on their business, but you are gearing up for entry into politics; what is the lure?


Mr Samuel Maduka Onyishi (Peace Mass Transit)

I do not think I want to be called a politician. Politics, for me, is a calling. I am into politics, because I want to be part of the decision-making process in the country. I know what Nigerians need, from my experience. I also know how the poor feel and I am in a privileged position to address the numerous challenges faced by the poor, the middle-class and the highly-placed in society.

If you consider my antecedents, you will understand that I started life as a poor man. I can never forget where I am coming from. I also have experience as a middle-class and as a highly-placed.

When businessmen shy away from politics, you can attribute that to lack of the sacrificial spirit and will power to solve the many demands of society. I have come to realise that God empowered wme to do same for others, and not to indulge in frivolous spending or the so-called ‘bigmanism’. Another reason is that I also want to leave a legacy, one which I will be remembered for.

When I was growing in business, I made a pact with God, telling Him that I will use the resources he availed me to bless him in return. What better way to do this than to render service to humanity?

Money is no legacy; if you leave that as a legacy for your children, they end up fighting over it and breeding hatred among themselves. But legacies are beyond money; they are more tangible and valuable.

You have been a member of the PDP since 1998; with the latest drama in the party, which of the factions are you loyal – the purported ‘New PDP’ as led by Baraje or the ‘mainstream PDP’ chaired by Tukur?

We don’t have factions in the Enugu State chapter of the party. We have only one PDP and it starts from the ward. In my ward, council, local government and state, we have only one PDP, and we don’t know any other PDP except the one whose chairman is Bamanga Tukur.

What is your take on the formation of the Baraje-led PDP?

You should be aware that the Independent National Election Commission (INEC) cannot register two PDPs. That said, I see what is happening now as a family problem that must be resolved. In that regard, President Jonathan is the leader of the party, the one playing a leading role by calling the family into the house to resolve contending issues. It is a family matter and, as such, must be tackled in-house. I am confident that the president is equal to the task.

There are reports that you are eyeing the number one seat in your state, Enugu, in 2015; can you confirm that?

Our governor, Sullivan Chime, has actually zoned the next governorship slot to Enugu North Senatorial Zone, which is Nsukka where I come from. The PDP in the state has also zoned it to Enugu North. Because they saw me grow from grass to grace and as a person they can trust, it is normal for them to beckon on me to represent them. I am not telling you whether I will run or not; what I am telling you that I am qualified to run. However, if my people say I should run, I cannot say no, because I have been an instrument of service to the people. That said, my decision is hinged on God’s approval.

How do you intend to do that in order to surpass the aforementioned strides of the former and current governors of the state?

Given the availability of funds, the potential to make more money for Enugu State and as an entrepreneur of repute, I believe that the God who has taught me how to create wealth and manage resources will not abandon me even as governor, hence, my strong belief that with the third eye of an entrepreneur, I will only do what I know how to do best. Enugu, at this time, needs a person who can sustain and improve ongoing development initiatives, and prepare it for the economic challenges ahead. With what is happening in the oil and gas sector, it is clear that so many countries are discovering oil at their backyards and, sooner than later, you will know that most of the countries who import oil from Nigeria have started discovering oil in their respective countries. A clear example is the United States of America (USA). When they tap into their new-found oil wells, they may not see the need to buy from us again. Now, since oil is our major source of revenue, this means that we would have lost our major source of income.

When this happens, the monthly allocation from the federal government will be reduced. States must strive to survive. The implication is that any state which cannot survive on its own through internally generated revenue to sustain development and service delivery is only sitting on a time bomb, and may not survive. The earlier we start planning for a Nigeria without oil, and an Enugu State without oil, the better for us. The future of the state, in terms of development, income generation and all other economic indicators depends on who the leaders are and their qualities – creativity, economic savvy and goodwill. I have done it before and, today, I have over 4,000 Nigerians on my payroll. I can do it again.

If I am a governor, the state will be more sustained under me. I will provide adequate security measures and build the capacity of my people through education, provision of good health facilities, agriculture, tackle unemployment among the people, especially the youths, provide sustainable job opportunities through agriculture and others.

Political pundits at different fora are of the opinion that President Jonathan is the most distracted and criticised leader in the world; if what they say is true, has it in any way affected his transformation agenda over the past two years? The opposition political parties are yet to see anything good that this government has achieved.

For me as a businessman, and as a believer in the transformation policies of Mr. President, the core aspect of every activity or programme is organisation. When turning around businesses to achieve transformation, many things ought to be put into consideration. Nigeria, because of our diverse culture and religion, needs some special skills to run. Jonathan has performed exceedingly well; his result in terms of achievement over the past two years is excellent. As a stakeholder in road transport business for now, I look at Nigeria from the road transport perspective; I knew how the roads were prior the assumption of office of the present administration. I am aware how the road from Enugu to Port Harcourt highway was; I know how the Enugu-Abakiliki road was. Apart from what the state governments are doing, the federal government is working assiduously on the major highways, building dual roads, massive construction of bridges and flyovers; you cannot start and finish constructing a 100-kilometre road in one month, therefore, he needs time for the result to manifest.
