I am a great scientist

Chapter 39 Is He Your Son?
"Xiaoxing, are you awake? When did you wake up?" Zhou Wenhua looked at Zhou Xing in surprise, and asked:

Zhou Xing turned over and got up from the bed, and said honestly: "Uncle, you woke me up! Your voice is too loud!"

Zhou Xing is not sleeping, he is conducting electronic experiments in the virtual laboratory.

The meal time was approaching, and the compulsory study status was lifted. When Zhou Xing was about to get up, he found someone chatting in a low voice in his room.

Not knowing who entered his room, Zhou Xing simply pretended to be asleep and listened, to see what they were going to do?
Thinking about it, Zhou Xing was overjoyed when he heard his father begging Liu Qiang to accept him as an apprentice to learn electronic knowledge, and he immediately woke up from pretending to sleep without even thinking about it.

Self-study and someone leading the way are two concepts. In the process of self-study, Zhou Xing encountered many problems. He needed to read a lot of materials to find the answers. Finding the answer is very annoying. Zhou Xing has already accumulated a lot of "difficult and miscellaneous diseases" for which he can't find the answer. He urgently needs the guidance of a famous teacher to solve his doubts.

"Stinky boy, you did a big thing without telling me, and I haven't settled with you yet, yet you dare to dislike my loud voice and itchy skin, don't you?" Zhou Wenhua gritted his teeth and said:

"Uncle, I'm sorry!" Zhou Xing smiled apologetically at Zhou Wenhua, then looked at Liu Qiang, and asked impatiently, "Uncle Liu, I happened to encounter some problems, can you help me answer them!"

"Yes! What's the problem?" Liu Qiang looked at Zhou Xing kindly, nodded and said:

"I designed a single-chip microcomputer to control the motor. Once the power is turned on, the buzzer keeps beeping, and it doesn't work when you press any key! What's the reason?" Zhou Xing asked puzzled:
"The buzzer sounds, and pin 2003 of ULN12 is low level, so is pin 5 also low level? If the relationship between 5 and 12 is not a NOT gate relationship, then there may be something wrong with ULN2003." Liu Qiang didn't even think about it, and directly Say:
Zhou Xing's eyes lit up, and after being reminded by Liu Qiang, he immediately figured out the reason.

"Thank you, Uncle Liu," Zhou Xing's eyes lit up, and he continued to ask, "I have another question. While the program is executing, the timer is also timing. The timer is an independent module, but the interrupt program affects the timing." The accuracy of the instrument, how can I solve it?"

"Well, when entering the interrupt program, first clear TF. The interrupt program should be short. Try not to call the same function as the main program. The execution of the program will affect the accuracy of the timer. When using the timer, It is necessary to consider the time consumed by interrupting the execution of standby, and give compensation in advance when the initial value of the calculator is set." Liu Qiang smiled slightly, and replied with a look of perplexity:
Zhou Xing suddenly looked surprised. Once this question was solved, it was actually not difficult at all, but he didn't think of it.

"Wow, that's incredible! How long have you been studying single-chip microcomputers? You can actually ask such a question, Xiaoxing, are you already engaged in the development of single-chip microcomputers?" Zhou Wenhua asked in surprise when he heard Zhou Xing's question:

"Well, I have been studying for ten days, and the development of single-chip microcomputer is too difficult!" Zhou Xing sighed and said helplessly:

The time limit for the system task is only 6 months, and fifteen days have passed. So far, I have only learned a little in the electronic field. An urgency never felt before.

Hearing this, the three of Zhou Wenhai looked at each other, seeing shock in each other's eyes.

"Ten days? These circuit diagrams are all designed by yourself? You soldered this switch control board?" Zhou Wenhua pointed to the blueprint on the desktop and a circuit board that was still running when it was powered on.

"Yeah! That pile of circuit boards are all experiments I just did: MCU serial communication, revolving lights, timing calculator, audio driver, LED dot matrix, temperature sensor,... I have done all the basic experiments that should be done!" Zhou Xing pointed to the two piles of circuit boards on both sides of the desk, and introduced:

"Xiaoxing, didn't you learn electronics after the college entrance examination?" Zhou Wenhua looked at Zhou Xing incredulously:

"The college entrance examination is not over, how can I have the time to do this!" Zhou Xing looked at Zhou Wenhua like a fool, and said angrily:
Hearing this, Zhou Wenhua gasped, "No comparison means no harm. Hearing Zhou Xing's words, he suffered [-] points of critical damage in his heart.

In college, Zhou Wenhua spent two years learning these basic knowledge. However, Zhou Xing only took a dozen days to master all of them, and his knowledge is more solid than him. With such a terrifying learning efficiency, is this guy still human? ?

It's too evil, there is a big evil in the Zhou family!
"Brother, he is your son, are you sure?" Zhou Wenhua looked at Zhou Wenhai in a daze, and asked stupidly:

Facing Zhou Wenhua's question, Zhou Wenhai smiled wryly, unable to answer this question. After all, he spent very little time with Zhou Xing. Aptitude for learning?

"Uncle, what do you mean? If you have the guts to ask my mother this question?" Zhou Xing glared at Zhou Wenhua angrily, and shouted:
Hearing this, Zhou Wenhai realized something, and immediately became angry: "Wenhua, what nonsense are you talking about! Your skin is itchy, right?"

"Brother, Xiaoxing, I'm sorry, I made a slip of the tongue, a slip of the tongue!" Zhou Wenhua smiled awkwardly, and apologized repeatedly:

"My mother is so kind to you, if she hears this,..., hum!" Zhou Xing snorted angrily.

Zhou Wenhua blushed, feeling ashamed at what Zhou Xing said, wishing he could dig a hole and bury himself.

"Haha, Xiaoxing, Wenhua is surprised by your talent, it doesn't mean that! You should spare him!" Liu Qiang laughed, and chimed in:
"Yes! Yes! Xiaoxing's talent is amazing. If we continue to learn at this speed, our factory will soon have a technical expert." Zhou Wenhua nodded excitedly:

"Yeah! However, Xiaoxing is going to college, so let's talk about residing in the factory after he graduates!" Zhou Wenhai said proudly:
"That's right, Xiaoxing is going to study at Peking University in one and a half months. If Xiaoxing wants any gift, just tell me, and my uncle will give it to you." Zhou Wenhua looked at Zhou Xing lovingly, and said generously:
"Xiaoxing, Dad is so happy that you can be admitted to university. Just tell me what you want, and Dad will do his best to satisfy you." Zhou Wenhai said happily:
Hearing this, Zhou Xing felt a pain in his heart, and his face was filled with bitterness. Before he got the system, he wished his father and uncle could tell him that most of his time can only be used for studying now, what needs does he have!

My life is so miserable!
