"Xiaoxing, are you awake, when did you wake up?" Zhou Wenhua looked at Zhou Xing with a look of surprise and asked:

Zhou Xing turned over and got up from the bed, and said honestly: "Uncle, I was woken up by you!

Zhou Xing is not sleeping, he is conducting electronic experiments in the virtual laboratory. Pen & Fun & Pavilion www.biquge.info

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

I don't know who entered his room, Zhou Xing simply pretended to be asleep and listened, to see what they were going to do?

Thinking about it, hearing his father begging Liu Qiang to take him as an apprentice and learn electronic knowledge, Zhou Xingdeng was overjoyed, and he didn't want to wake up from pretending to be asleep immediately.

Self-study and someone to lead the way two concepts, the process of self-learning, Zhou Xing encountered a lot of problems, need to read a lot of information to find the answer, sometimes even have nowhere to find the answer, can only silently keep the problem in mind, slowly look for the answer, very annoying, Zhou Xing has accumulated a lot of can't find the answer to the 'incurable diseases', urgently need a famous teacher to guide him, for him to solve his doubts.

"Stinky boy, I did a big thing without me, and I haven't even settled accounts with you, you dare to dislike me for having a loud voice and itchy skin, 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 couldn't wait to ask: "Uncle Liu, I happened to encounter a few problems, can you help me solve 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, and as soon as the power is turned on, the beeping device keeps ringing, and pressing any key can't work properly! What is the reason?" Zhou Xing asked puzzledly:

"When the buzzer sounds, the 12 pins of the ULN2003 are low, and the 5 pins are also low? If the relationship between 5 and 12 is not NAND gate, then there may be a problem with ULN2003. Liu Qiang didn't think about it, and said directly:

Zhou Xing's eyes lit up, and 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 still have a problem, the program is executing at the same time, the timer is also timing, the timer is an independent module, but interrupting the program affects the accuracy of the timer, how can I solve it?"

"Well, when entering the interrupt program, first clear the 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 timing with the timer, you should consider the consumption time of interrupt execution standby, and compensate in advance when the initial value of the calculator. Liu Qiang smiled slightly, and replied with a look of embarrassment:

Zhou Xing suddenly showed a sudden expression, as soon as this question is explained, it is actually not difficult at all, but he didn't expect it.

"Wow, it's amazing! How long have you been learning single-chip microcomputer? Can you ask this kind of question, Xiaoxing, are you already engaged in single-chip microcomputer development?" Zhou Wenhua heard Zhou Xing's question and asked in surprise:

"Well, I've been studying for more than ten days, and it's too difficult to develop a single-chip microcomputer!" Zhou Xing sighed and said helplessly:

The time limit for the system task is only 6 months, fifteen days have passed, so far I have only learned a little bit of the surface of the electronic field, the task has made no progress, and even the direction of the paper cannot be determined, time passes day by day, Zhou Xing feels an unprecedented urgency.

Hearing this, Zhou Wenhai and the three of them glanced at each other, and they all saw a trace of shock in each other's eyes.

"Ten days? These circuit diagrams are all designed and painted by yourself? And this switch control board is soldered by yourself?" Zhou Wenhua pointed to the drawings on the desktop, and a circuit board that was still running after being energized, his face changed drastically, and his face was full of incredulity:

"Yes, those circuit boards are all experiments that I have just done: microcontroller serial port communication, marquee, timing calculator, audio driver, LED dot matrix, temperature sensor,... , I've done all the basic experiments that should be done!" Zhou Xing pointed to the two stacks of circuit boards on both sides of the desk and nodded:

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

"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 asked angrily:

Zhou Wenhua gasped, there was no harm if there was no comparison, and after listening to Zhou Xing's words, his heart suddenly suffered 10,000 points of critical damage.

When he was in college, Zhou Wenhua spent two years learning these basic knowledge, however, Zhou Xing mastered them all in more than ten days, and the knowledge was more solid than him, such a terrifying learning efficiency, is this guy still human?

It's too demonic, there is a big demon in the Zhou family!

"Brother, this is a son, are you sure?" Zhou Wenhua looked at Zhou Wenhai with a confused expression, and asked stupidly:

Facing Zhou Wenhua's question, Zhou Wenhai smiled bitterly, unable to answer this question, after all, he had little time with Zhou Xing, and Zhou Xing had given up on himself before, his playthings were demoralized, and he didn't have any intention to study, how could he have the opportunity to understand Zhou Xing's talent in learning!

"Uncle, what do you mean? Do you dare to ask my mother about this question?" Zhou Xing glared at Zhou Wenhua angrily and roared:

Hearing this, Zhou Wenhai realized something, and he was also angry: "Wenhua, what are you talking nonsense!

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

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

Zhou Wenhua's old face turned red, and he was embarrassed by Zhou Xing's words, and he couldn't wait to dig a hole and bury himself.

"Haha, Xiaoxing, Wenhua is surprised by your talent, I don't mean that! You spare him!" Liu Qiang laughed and hurriedly said:

"Yes! Yes! Xiaoxing's talent is amazing, and if we continue to learn at this speed, our factory will soon have a technical power. Zhou Wenhua nodded excitedly:

"Well, however, Xiaoxing is going to college, and the matter of staying in the factory will wait for him to graduate!" Zhou Wenhai said proudly:

"That's right, in another month and a half, Xiaoxing will go to Peking University to study, what gift does Xiaoxing want, just say, Uncle will give you. Zhou Wenhua looked at Zhou Xing fondly, and said:

"Xiaoxing, you can be admitted to university, Dad is so happy, just say what you want, Dad will do his best to satisfy you. Zhou Wenhai smiled brightly and said happily:

Hearing this, Zhou Xing's heart hurt greatly, his face was full of bitterness, before he got the system, he wished that his father and uncle could say this, now most of the time can only be used to study, what else does he need!

My life is so miserable....
