Dummies four time limit: 1000 MS | memory limit: 65535 kb difficulty: 3 Description These days, dummies have been studying stocks. After research, they finally found that the stock laws of XXX company. what's even better is that dummies work out the company's stock price every day to prevent others from discovering its secrets. He decided to buy the c

objective, users are objective, users are objective, and needs are objective. Everything is realistic.2. Principle 1: the customer is always right.Customers are not our enemies, and customers will not harm us. The customer's demands seem to embarrass us, but they are essentially trying to make customers better use their products. Therefore, customers will not embarrass themselves.3. Principle 2: provide the most appropriate solution, not the best or most expensive solution.What we can do is not

through the whole Echo process and tell you that I can't do it either ). Keep a low profile, so I think of myself as a new person. Looking back on these two years, I always feel empty!4. "What are my rights and obligations? What are my responsibilities? "Both Echo and Reecho have this feeling. It seems that everything needs to be done. But when you make suggestions and criticisms, no one cares about you. 'Who are you, how sad it is to listen to you. Because I am only a developer, of course I ca

Bolg is not just an original article. Of course there are somePseudo-originalThe article, the pseudo-good or bad, the selection of the article, has been plagued by new users such as me. Many of my friends copied some popular articles and made changes, and then posted them on their websites in a rush. Finally, Baidu only recorded the homepage, it is very difficult, but google is doing better in this regard, and the record is OK. Here, Chen tofu also shares the operating ideas and techniques of hi

I feel sick when I see the dummies of my dreams !" Lu Fei: suo long, this is definitely not a fight! Have you ever wondered why this is definitely not a fight? Why not defend your dreams? Lu Fei knew that they were not a means to defend their dreams, so he

access the internet. I really want to spend a lot of time studying how Linux works documents, only a few Linux developers and enthusiasts can access the Internet and achieve multimedia.======================================The features you need can be fully met in windows. I don't know why you have to look for Linux. If you really want to study it, be humble.A little. Windows is like a dummies camera. It's very easy to use. Linux is a professional ca

how did you do it? There are hundreds of thousands of combs, but there are hundreds of thousands of dollars. Where do you come with so much money ?" LV Bu smiled and said, "What is it about weak meat? Where is the weakness? All on this head! Therefore, every business-minded person will look at a group of dummies and dummies. Dong Zhuo will be like this, so will Lu Bu. He used his monthly salary of Yuan as

engineer! [3] Do not be a technical master, but a general quality master! When we are in a company, we often look down on someone and say, "I don't know anything. Why do we get so much money and why do we get promoted !" This is a common example of engineer pedantic. Is 8051 awesome? People must have his skills, and you cannot. Do you think the boss has been operating for so many years? People may be good at management, understanding the boss's intentions, and department coordination. Therefore

, because the company will ask you for Bootloader during interviews, as a product. (3)We will have a preliminary understanding of the working process of arm11 and wince, and some knowledge of bootloader is more valuable than simple drivers. (4)It is necessary to implement the underlying layer. (5)I think it is necessary to learn bootloader. Otherwise, jumping directly to the wince driver development without going through the bootloader stage will give people a feeling of overhead. 2. What hardw

comprehensive quality, we have no way to go. Otherwise, we can only look at the oscilloscope in the corner! Skills other than technology are more important !! From ancient times to the present, the United States and Japan are all like this![4] Make Friends of the social education community! Do not interact with engineers only, think that there is a common language, but more importantly, communicate with other people. If you want to be a boss or a sen

received. Why can't the last byte be read during continuous reading? It is tested that this problem does not occur when the log is opened, so it can be confirmed that the delay at a specific location is insufficient. By observing the waveform through the oscilloscope, we can see that the last byte has been read, and the Stop waveform is also displayed, therefore, it is determined that the last byte has not entered the FIFO before the last read of RX-

He wasn' t supposed to build just any televisionSet, but one that wocould be the absolute best of all televisions. ThisWas not a problem for Baer, but he wanted to go beyond his originalAssignment and ineffecate (include, add, absorb)Some kind of game into the set. He didn'tKnow exactly what k

microcomputer is not running after power-on?First, check whether the power supply voltage is normal. Use a voltmeter to measure the voltage between the grounding pin and the power supply pin to see if it is the power supply voltage, such as the commonly used 5 V.Next, check whether the reset pin voltage is normal. Measure the voltage values of the reset button and the open reset button to see if they are correct.Then check whether the crystal oscillator is vibrating. Generally, use an

If the highest bit is 1, the write protection status is enabled. 3. Unable to chargeThe power-on charging function of ds1302 is disabled.

Some time ago, I debugged the mcp2515 driver in Linux. The driver basically passed the debugging. Some problems occurred when I debugged several other boards in the past two days. 1. When Linux is started, probe mcp2515 sometimes fails, sometimes succeeds, and some boards can always be successful. When the probe fails, the message "mcp251x didn't enter in conf mode after reset" is displayed ". Debugging analysis: During probe, the driver reset mcp2515 adopts the SPI command reset form, and the

written, you can use an oscilloscope to directly measure the clock to see if it is the number you configured, the next step is to test the memory. This test must write a simple small program. In fact, it is mainly to test whether the data bus works normally. If there is a problem when configuring the minimum system, there are two common problems, first, the register is incorrectly configured. The solution is to combine examples and engineerTo enginee
