Black technology: I can decompose everything

Chapter 22 CD-ROM
A whole large sketch paper was filled with circuit diagrams, and the labels of various diodes, triodes, resistors, and capacitors were all marked on it.

It's just that there is no single-chip microcomputer in this circuit diagram, because this circuit diagram is only the most original design diagram of the controller.

He has not replaced the place where the single-chip microcomputer can be used in the picture. It can be said that the picture is extremely bloated now.

If you do it according to this picture, it is very likely that there will be bugs during operation, and this situation will still occur with a high probability.

After he finished drawing this most original circuit diagram, he was about to start modifying the diagram.

This is also the reason why he could only continue downward after he found the design drawings and functions of various single-chip microcomputers on the Internet.

Although he doesn't know many single-chip microcomputers now, he also compared various models and chose a model that not only takes into account cost but also has performance, which is extremely cost-effective.

The simplification of the circuit diagram is not achieved overnight. It is the same as the situation when he first designed it. He also changed half of the simulation and then discarded it, and then continued downward.

Before he knew it, his desk was covered with many sheets of paper, some of which were almost finished, and some of which were just beginning.

And when he was trying to design a controller, there was a person in the school who was gnashing his teeth and learning.

When the time slowly came to almost ten o'clock, the door of his bedroom was pushed open from the outside, and he was concentrating on changing the picture, but he didn't notice anyone coming in at all.

It was none other than his father Li Min'an who came in, and at the moment he was holding a small black plastic bound notebook.

Looking at his son who was extremely serious, Li Min'an realized that he didn't attract his son's attention, and he didn't make any noise. Instead, he quietly walked behind him, wanting to see what he was doing.

He looked at the paper that Li Zhenhua was drawing, and then he lost interest because he couldn't understand it at all.

For him who has been a soldier and then a policeman, he is good at catching a tongue and catching a thief, but it is really incomprehensible to see such things.

Although this picture does not seem to be learning the knowledge used in a serious exam, but my son said before that he wants to learn things after college, so he didn't bother him.

Gently patted him on the back, and then sat on the edge of the bed. Only then did Li Zhenhua realize that someone was there, and turned his head to see that it was him who stopped what he was doing.

I saw his father put the small book in his hand on the table and gently pushed it to him, allowing him to see the words on the small book.

"You said before that you wanted to apply for a driver's license. I've done it for you. In fact, I got it half a month ago, but I didn't give it to you. But after what happened today, I think I should give it to you!"

Looking at the driver's license on the table, he was very happy to hold it in his hand. When he opened it, it looked the same, and found that he had not only got a C1, but also a D. At this moment, he suddenly felt that his father understood him very well.

"Thank you dad, you are so kind!"

"Don't thank me in a hurry, I still have to tell you something before that, although I have issued a driver's license for you, you must first obtain my approval before you can drive, and you can't think about it until you meet my requirements Move!"

He nodded to Li Min'an and said, "Of course, before I get your consent, I promise you that I will never move the car!"

"Okay, as long as you know what's in your mind, it's not too early, go to bed early!" After receiving his assurance, Li Min'an didn't say much, just gave a few words, and then got up and walked towards the door.

Hearing his father's instructions, he realized that it was already so late. He looked at the half-modified design drawings on the table, then put away all the drawings, and then ran to wash up.

The design of this controller can't be done in a day, so he is not in a hurry, anyway, he will have plenty of time since he won't go to study at night.

After washing up, he went straight to rest, and he slept very comfortably and comfortably that night!

When he came to school the next day and just sat down, someone grabbed his neck and shook him. Before he could react, he heard a sound reaching his ears.

"Damn you, Li Zhenhua, I'm fucking envious of you, I wish you could die immediately!"

His deskmate, Sun Xin, was really envious of him. His academic performance improved, and he didn't have to go to evening self-study. What a wonderful thing, but it happened to his deskmate, and he couldn't help but be jealous.

Seeing the envious, jealous and hateful expression on Sun Xin's face, he was not to mention how happy he was. The relationship between the two is that of a bad friend who can't see a brother's good. His happiness is based on the other's pain.

After agreeing to treat him to breakfast, he finally got rid of Sun Xin's shaking, and then another day of study began.

After school at noon, he called his mother at the canteen at the gate of the school, and said that he would not go to eat. He was going to the bookstore to see if there were any software CDs he needed for sale.

Then he went to Xinhua Bookstore, but he couldn't find it after searching around the bookstore. There were only CDs of various songs and movies in the store.

Somewhat unwillingly, he asked the clerk a question, and while he was dumbfounded, the clerk brought out a box from under the counter.

"You can look for it here, and pick out the useful ones. The price is ten yuan a piece. The tasks assigned by this thing have been suppressed for a long time and no one has bought them. It's best for you to buy them all. Walk!"

Looking at the box with a lot of CDs already covered with a layer of dust, I thought silently in my heart. 'Sure enough, it's the style of these days! '

While thinking about it, he rummaged through the box, and he really found something good in it, which contained all the software CDs he needed, CAD14.0, space c (C/c++ language programming software)...

It was a surprise that he could find all the software in one stop here. He thought the process would be tortuous!

In the box are not only these, but also let him find some game discs, cs1.5, Red Alert 2 Yuri's Revenge, StarCraft and many other games that are still fresh in his memory.

Picking and picking in the box, he picked out a total of ten discs together with the software and games. After his small coffers shrank again, he took all the discs out.

He also sensed a sense of urgency for the shrinking small coffers in his eyes. They all said that money is a hero's guts, and gold is a man's waist. Now he desperately wants to have money.

He left the bookstore happily, and the bookstore clerk was also very happy after he left. Some of the overstocked items were finally sold, and he had something to say to the leader.

With these software, his next plan can be officially started, and he no longer needs to use sketch paper to draw design drawings.

After eating something on the road, he carried these discs and went back to school. He was looking forward to it all afternoon, looking forward to installing all these softwares when he got home at night, wishing he could start working immediately.
