51 uses assembly language, which is a compulsory course in the electrical, automation, microelectronics and other electrical colleges. Every student in the electrical college has learned it, but it is less able to apply what he has learned. It is no exaggeration to say that Liu Chen is building 51 hardware on CPLD and FPGA, and he is very familiar with its assembly driver.

Liu Chen clicked over and saw it with a glance. The main program, interrupted call, reset, drive, and detect. Liu Chen nodded and said to Fang Zhigao beside him: "The program logic is great."

Fang Zhigao smiled shyly, and was shocked again. He thought he had seen Mr. Liu's limits every time, but Mr. Liu was shocked every time he made an action.

When laymen watch the fun, experts look at the tricks. Fang Zhigao believes that he has the highest level of embedded development, especially 51 chips, and uses assembly as C, which is very few people can do this.

Witnessing Liu Chen's development process, he understood that this was an embedded master, and that the theory and hardware level reached a level of perfection. It was impossible to achieve this without a few years of immersion experience. He felt frustrated in his heart. In just a moment, he was more excited and itchy. In the past, he could not devote himself to it.

Now, he must reach Liu Chen's height and even surpass it. This kind of pleasure that can be easily enjoyed is really fucking.

Liu Chen found the location of the control logic, started writing 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 said softly, "Can you fly?"

Everyone was also confused when they saw his series of actions. At this moment, they held their breath and looked at it with wide eyes, thinking that if they couldn't fly, it would be embarrassing.

Liu Chen pressed the power switch, and the four stepper motors rotated, shaking for a while and then flew up. Everyone opened their eyes wide. It was really possible to fly. It was unbelievable. It was only a dozen minutes.

Turning stones into gold, watching the scene that turns decay into magic.

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

Liu Chen's expression was still calm, staring at the small plane slowly flew up, and it was not enough to reach a complete balance in the air, and it was very likely to rush up the roof.

Even so, everyone found it amazing.

He quickly tore a piece of white paper into pieces and kneaded it into small balls and particles. Liu Chen gently put it into the small pallet under the small plane. After putting three, the small plane stabilized and floated up and down in a small area, looking like it was spiritual.

"It's really possible to fly."

"It's still floating in the air."

Li Lin and Wan Niu exclaimed that their professionalism was incredible to them, but it happened in front of them.

Guo Liang and Shi Sen are both technical experts, with solemn and meditative eyes, no remote control, and paper scraps. In their opinion, low-level methods that they disdained can have a big effect.

"If I were to be bigger, wouldn't I take me into the air?" He Qian was most excited and couldn't hold back his body.

"The technical difficulty of a four-rotor aircraft lies in autonomous hovering. Today, I just throw a brick for you. The stepper motor has little power and is replaced with a permanent magnet synchronous motor. It is not easy to control accurately. There are also long-distance communication, picture transmission and other issues." Liu Chen said.

Fang Zhigao started to applaud, and everyone followed him, and the small plane was still hovering, so he couldn't help but accept it.

"When the wheel rotates around the ground, the curve that passes through a certain point on the circumference of the wheel is called a rotary wheel line." Liu Chen said and drew it on the whiteboard, "In mathematics and physics, rotary wheel lines have very important and beautiful properties."

He Qian was quick-witted and reached out and shouted, "For example, the area below a section of rotating wheel line is exactly three times the area of ​​this circle."

After all, he is a young man, and his personality is almost instinctive.

Liu Chen nodded with a smile and said, "This conclusion was first discovered by Galileo. However, in the era without calculus, calculating the area below the curve is almost an impossible task. How did Galileo find it?"

He Qian did not speak anymore, but started to think about it, and had no idea for a while.

"His method is so simple that it is so simple that he cuts out the shape of a rotating wheel line on the metal plate and weighs it on the scale. He found that the weight is exactly three times that of the corresponding circular metal sheet. After trying all kinds of mathematical methods but failing, Galileo decisively acted as a rogue and used physical experiments to measure the area of ​​the figure."

With a little humor, all the academic masters present laughed out loud. This was the excitement point of the academic masters. The shock just now, they were thinking about Liu Chen's words, and their thinking quietly changed.

"The generalized Fermat problem can be solved with a set of uncomplexing mechanical systems, and the Steiner problem can also be instantly killed with soap film experiments. In fact, hardware does not require such complex theoretical modeling. I hope you can take aerial photos of the Bund in Jianghai in one month."

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

How big a person can do depends on how big he thinks he can do. Before no one climbs Mount Everest, anyone thinks it is impossible. When someone does it, you will say, oh, it can still be done.

When Ergouzi around you did it, you will think, I am a grass-hit-mom, this is OK, I will definitely have no problem, so you also went to climb. If you encounter many difficulties in the middle, you will also firmly believe that I will not be worse than that.

Today, Liu Chen opened a window for them. It turned out that technology could reach this level. Someone did it, and it was right in front of me, so I can do it too.

Fang Zhigao has always felt that he was awesome in technology and theoretical height. He has learned to the doctoral level in two years. In terms of hardware, he even killed doctoral graduates in seconds. He often lamented that his fate was unfair. After these two days of contact, he realized that there was still a lot of room for improvement. He was eager to make progress and change the world with his bare hands.

"In one month, we will definitely be able to take aerial photos of the Bund."

After saying that, Liu Chen left, sat down in the general manager's office, and looked at the basic management book online. How can we stimulate the enthusiasm of scientific researchers to the greatest extent while ensuring freedom? Just like couriers receiving and dispatching personnel, how can we quantify work? Liu Chen understands very well that a set of management methods is to leave behind the magic weapon for these top students.

In the afternoon, Ba E-commerce continued the interview. When Liu Chen arrived, he saw how many people he had seen, but the number was smaller. However, they were all very serious and looked cold and arrogant. He actually saw an acquaintance again, Professor Chang's disciple Bai Lei, who was also the president of the Student Union, and was also attracted by surprise.
