readx;? 51 using assembly language, this is electrical, automation, microelectronics and other major courses in the electrical academy, every student in the institute has learned, but can achieve the degree of application of what they have learned, it is no exaggeration to say, Liu Chen is a piece of cake in building 51 hardware, very familiar with its assembly driver. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Liu Chen clicked over, and knew at a glance, the main program, interrupt call, reset, drive, detect, Liu Chen nodded, and said to Fang Zhigao on the side: "The program logic is great." ”

Fang Zhi smiled shyly, and was shocked again, he thought he had seen Mr. Liu's limit every time, but Mr. Liu was shocked every time he made a move.

The layman looks at the excitement, the insider looks at the doorway, Fang Zhigao believes that he has the highest level of embedded development, especially the 51 chip, and uses the assembly as C, and few people can do this.

Witnessing Liu Chen's development process, he understood that this was an embedded master, and the level of theory combined with hardware reached the point of perfection, which was difficult to achieve without a few years of immersion experience, and there was a sense of frustration in his heart, just for a moment, more excitement, itchy hands, and he couldn't devote himself to it in the past.

Now, he must also reach Liu Chen's height, or even surpass, this kind of heartiness is really cool.

Liu Chen found the location of the control logic, began to write it, added the feedback control unit, and it was done in just a few minutes, the compilation was passed, the chip was written, the developer was unplugged, and he whispered, "Can you fly?"

Everyone looked at his series of movements and was also blindfolded, holding his breath at the moment, watching with wide eyes, and said in his heart, if he couldn't fly, it would be too big.

Liu Chen pressed the power switch, the four stepper motors rotated, shook and then flew up, everyone's eyes widened, they could really fly, unbelievable, it was only ten minutes.

Turning stones into gold, watching the scene of decay turning into magic.

He Qian jumped up excitedly, and suddenly became extremely interested in hardware development.

Liu Chen's expression was still indifferent, staring, the small plane slowly flew up, and it could not fully reach balance in the air, and there was a tendency to rush to the roof.

Even so, everyone thought it was amazing.

Quickly tore a piece of white paper into pieces, crumpled it into small balls and small grains, Liu Chen gently put it into the small tray under the small plane, and after putting three of them, the small plane stabilized, floating up and down in a small area, looking like a spirit.

"You can really fly. ”

"It's still suspended in the air. ”

Li Lin and Wan Niu exclaimed, their professional bias was theoretical, which seemed to them to be incredible, but it happened right in front of them.

Guo Liang and Shi Sen are both technical masters, their eyebrows are dignified, contemplative, they don't need remote control, and they also add confetti, which is a low-level means that they disdain in their opinion, but it can have a big effect.

"If you make it bigger, won't you be able to fly me into the air. "He Qian is the most excited at his young age, and he can't help himself.

"The technical difficulty of quadcopter is autonomous hovering, today, I just throw a brick for you, the stepper motor has little power, replaced by a permanent magnet synchronous motor, precise control is not so easy, and there are long-distance communication, picture transmission and other problems. Liu Chen said.

Fang Zhigao began to applaud, the big guys also followed, and the small plane was still hovering, so I couldn't help but be unconvinced.

"When the wheel rotates once on the ground, the curve that is crossed at a point around the circumference of the wheel is called the spinning line. Liu Chen said and drew it on the whiteboard, "In mathematics and physics, the spiral line has very important and beautiful properties. ”

He Qian was quick to think and stretched out his hand and shouted: "For example, the area below a section of the wheel line is exactly three times the area of this circle. ”

In the end, he is a young man, and his limelight is almost instinctive.

Liu Chen nodded with a smile and said, "This conclusion was first discovered by Galileo. However, in the era of calculus, calculating the area below a curve was an almost impossible task. How did Galileo find out?"

He Qian didn't speak again, but used his brain to ponder, and he didn't have an idea for a while.

His method was outrageously simple: he cut out the shape of a spinning wheel wire in a metal plate, weighed it on a scale, and found that it weighed exactly three times the weight of its round metal counterpart. After trying all kinds of mathematical methods and failing to do so, Galileo decisively played the trick of hooliganism and used physical experiments to measure the area of the figure. ”

A little humor, the top students present all laughed, this is the excitement of the top students, the shock just now, for Liu Chen's words, they are all thinking, and their thinking has quietly changed.

"The generalized Fermat point problem can be solved with a set of uncomplicated mechanical systems, the Steiner problem can also be killed instantly with soap film experiments, and the hardware does not need to be so complex theoretical modeling, I hope you can take aerial photos of the Bund in the river and sea in a month. ”

After speaking, Liu Chen had already left the laboratory, and the words were still echoing in everyone's ears.

How much a person can do is how much he thinks he can do, and until no one climbs Mount Everest, anybody thinks it's impossible, and when somebody does it, you say, oh, it can still be done.

When the second dog next to you does it, you will think, I grass--, this ** is fine, I must be fine, so you also went to climb, encountered many difficulties on the way, you will also strengthen your belief, I will not be worse than that **.

Today, Liu Chen opened a window for them, it turns out that technology can reach this level, someone has done it, and it is right in front of me, then I can too.

Fang Zhigao has always felt that he is awesome enough in technology, theoretical height, he has learned the doctoral level in two years, hardware, is a second kill doctoral graduates, often sigh the unfair fate, these two days of contact, he understands that there is still a lot of room for growth, he is eager to make further progress, and change the world with his bare hands.

"A month later, we will be able to do it by aerial photography of the Bund. ”

After speaking, Liu Chen left, sat down in the general manager's office, and looked at the basic management books from the Internet, how can the enthusiasm of scientific research personnel be stimulated to the greatest extent under the condition of ensuring freedom, just like the courier delivery person, how to quantify the work? Liu Chen understands very well that a set of management methods is the magic weapon to leave these high-achieving students.

In the afternoon, Ba E-commerce continued to interview, and when Liu Chen arrived, he deliberately looked at how many people had come down, but the number was less, but all of them were very solemn, their faces were cold and arrogant, and they actually saw an acquaintance, Bai Lei, a disciple of Professor Chang, this guy is still the president of the student union, and he was also attracted by the surprise.

Liu Chen was even more surprised when he saw another person. (To be continued.) )
