"Xiao Xing, are you awake? When did you wake up?" Zhou Wenhua looked at Zhou Xing with surprise and asked:
Zhou Xing turned over and got up from the bed, and said honestly: "Uncle, you woke me up! You were too loud!"
Zhou Xing is not sleeping, he is conducting electronic experiments in the virtual laboratory.
It was almost lunchtime and the forced study state 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 planning to do.
When he heard that his father begged Liu Qiang to accept him as his apprentice and learn electronic knowledge, Zhou Xing was overjoyed and immediately woke up from pretending to be asleep without even thinking about it.
Self-study and having someone lead the way are two different concepts. During the self-study process, Zhou Xing encountered many problems and needed to read a lot of information to find the answer. Sometimes there was no place to find the answer, so he could only silently keep the problem in mind, and slowly Looking for answers is very annoying. Zhou Xing has accumulated a lot of "difficult diseases" for which he cannot find answers. He is in urgent need of the guidance of a famous teacher to help him solve his doubts.
"You brat, you did something big without telling me, and I haven't even settled the accounts with you yet. How dare you despise me for having a loud voice? It's making my skin itch, right?" Zhou Wenhua gritted his teeth and said:
"Uncle, I'm sorry!" Zhou Xingchong smiled apologetically at Zhou Wenhua, then looked at Liu Qiang and asked impatiently: "Uncle Liu, I happened to encounter a few difficult problems, can you help me answer them!"
"Okay! What's the problem?" Liu Qiang looked at Zhou Xing kindly, nodded and said:
"I designed a microcontroller to control the motor. The beeper keeps beeping as soon as the power is turned on, and it cannot work normally when I press any button! What's the reason?" Zhou Xing asked puzzledly:
"The buzzer sounds. Pin 12 of ULN2003 is at low level. Is pin 5 also measuring low level? If the relationship between 5 and 12 is not a NOT gate, then there may be something wrong with ULN2003." Liu Qiang didn't even think about it, and directly explain:
Zhou Xing's eyes lit up. He was reminded by Liu Qiang and immediately understood 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 interrupting the program affects the timing. How can I solve the problem of instrument accuracy?"
"Well, when entering the interrupt program, clear TF first. 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, We must consider the time consumed by interrupt execution and standby, and compensate it in advance when setting the initial value of the calculator." Liu Qiang smiled slightly and replied in a difficult tone:
Zhou Xingdun showed a look of surprise. Once the question was answered, it was actually not difficult at all. It was just that he had not thought of it.
"Wow, that's incredible! How long have you been studying microcontrollers? You can actually ask this kind of question, Xiaoxing, are you already engaged in microcontroller development?" Zhou Wenhua asked in surprise when he heard Zhou Xing's question:
"Well, I've been learning for more than ten days. Microcontroller development is too difficult!" Zhou Xing sighed and said helplessly:
The time limit for the system task is only 6 months, and it has been fifteen days. So far, I have only learned a little bit about the electronic field. There is no progress in the task, and I can't even determine the direction of the paper. As time passes day by day, Zhou Xing feels An unprecedented urgency.
Hearing this, Zhou Wenhai and the other three looked at each other and saw shock in each other's eyes.
"Ten days? Did you design these circuit diagrams by yourself? Did you weld this switch control board?" Zhou Wenhua pointed at the drawings on the table and a circuit board that was powered on and still running. His expression changed drastically and he was filled with disbelief:
"Yes! Those piles of circuit boards are all experiments I just did recently: microcontroller serial communication, revolving lantern, timing calculator, audio driver, LED matrix, temperature sensor... I have completed all the basic experiments that need to be done!" Zhou Xing Pointing to the two piles of circuit boards on both sides of the desk, he introduced:
"Xiao Xing, didn't you learn electronics after the college entrance examination?" Zhou Wenhua looked at Zhou Xing in disbelief:
"The college entrance examination is not over yet, 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 took a deep breath. Without comparison, there would be no harm. After hearing Zhou Xing's words, his heart suddenly suffered 10,000 points of critical damage.
During his college days, Zhou Wenhua spent two years learning these basic knowledge. However, Zhou Xing mastered them all in just a dozen days, and the knowledge he learned was more solid than him. With such a terrifying learning efficiency, is this guy still human?
What a monster! A big monster has appeared in the Zhou family!
"Brother, he is your son, are you sure?" Zhou Wenhua looked at Zhou Wenhai in confusion and asked stupidly:
Faced with Zhou Wenhua's question, Zhou Wenhai smiled bitterly, unable to answer the question. After all, he had spent very little time with Zhou Xing. Before joining Zhou Xing, he gave up on himself, lost his mind in playing with things, and had no intention of learning. How could he have the chance to understand Zhou Xing? A talent for learning
"Uncle, what do you mean? How dare you ask my mother this question?" Zhou Xing glared at Zhou Wenhua and yelled:
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!" Zhou Wenhua smiled and apologized embarrassingly:
"I don't think my mother is so good to you. If she hears this... Humph!" Zhou Xing snorted angrily.
Zhou Wenhua's old face turned red. He was so embarrassed by Zhou Xing's words that he wished he could dig a hole and bury himself.
"Haha, Xiaoxing, Wenhua is surprised by your talent, that's not what it means! Please spare him!" Liu Qiang laughed and said in support:
"Yes! Yes! Xiaoxing's talent is so amazing. If he continues to learn at this speed, our factory will soon have a technical expert." Zhou Wenhua nodded excitedly:
"Yeah! However, Xiaoxing is going to college. Let's wait until he graduates to work in the factory!" Zhou Wenhai said proudly:
"Yes, Xiaoxing will go to Peking University in one and a half months. If Xiaoxing wants any gifts, just tell me. My uncle will give them to you." Zhou Wenhua looked at Zhou Xing lovingly and said generously:
"Xiaoxing, dad is so happy that you can go to college. Just say whatever you want, and dad will try his best to satisfy you." Zhou Wenhai said happily:
Hearing this, Zhou Xing felt a pain in his heart and his face was full of bitterness. Before he got the system, he wished his father and uncle could tell him this. Now he can only spend most of his time studying, so what does he need
My life is so miserable!
