Chapter 10
It was two weeks later that Ye Li was called to the office by Tong Yan again.
"Here?" Tong Yan saw Ye Li enter the door, and stopped what he was doing, "Wait a minute, I'll go find Lin Li."
Ye Li stood in the room, looking around.It's the end of November, and the school has started to heat up.Although this department building has been built for a few years, Tong Yan's office is in the shade, the lighting is not good, the temperature is low, and unlike other houses, there are many flowers and green plants.Tong Yan doesn't seem to care much about his working environment, and he has a strong endurance.Wear long-sleeved shirts in summer, and just an extra top in winter.
The mainframe of the desktop computer on the table is covered with notices, with flying and flying phoenixes written on it, "Party meeting at x o'clock in the morning of x week", "doctoral student defense meeting in conference room xx", "mid-term summary of no. xx" and so on. memo.In addition to the bookcase and table, there is also a water dispenser, and the glass on the table is also the simplest white water.Steam was rising from the cup.
"Come on, let's get acquainted." Tong Yan said as he entered the room.Ye Li saw that it was indeed Lin Li.
Before he could speak, Lin Li smiled: "Teacher Tong, you don't need to introduce me. I ran with Ye Li last night."
"Oh?" Tong Yan glanced at Ye Li, then at Lin Li, "Have all the new students been dragged in?"
"Yeah, I told you to run together and you still haven't come."
Tong Yan pulled out his chair and sat down: "I won't come, it's too time-consuming."
"It's just like you, who work all day and night, and the body is more likely to have hidden dangers. The most important thing is to run more and exercise your heart and lung function. The youngest doctoral supervisor at the C University next door died of a heart attack. You heard What?" Lin Li circled around and stood behind Tong Yan.
"I heard. You are expecting my sudden death. No one is watching you work."
"That's not what I meant." Lin Li smiled and blinked at Ye Li, then tilted her head to look at Tong Yan's expression from behind, "I'm worried that you are overworked."
Tong Yan said without looking back: "You can save me a lot of worry by using your own brain."
Lin Li squeezed her nose at the back of Tong Yan's head and said nothing.Tong Yan took a small box and a stack of documents.
"This is the chip to be tested this time, the ARM core, and five samples are given. This is the manual. The main task is to design the test circuit first, make the test board, then program, and do the test experiment. I thought about it, because Lin Li still There is a final design to be done, so Ye Li is mainly in charge, and you can ask Lin Li if you have any questions."
Tong Yan explained a few more words, and led them to the diagonally opposite room, where there were four tables in total.On the table are two computers, an oscilloscope, and some odd tools for making circuit boards, such as soldering irons, welding rods, and pliers.
"Ye Li, sit here." Tong Yan pointed to the seat next to Lin Li, "I have other things, please ask me if you have any questions."
Ye Li sat down and turned on the computer.Although this computer is an old computer and the model is relatively old, it is still something he can use casually.In the past, if he wanted to surf the Internet, he had to go to the public computer room of the school. Although it was not expensive, he had to pay for it.
This is Ye Li's first "laboratory".
"Senior Sister?" Ye Li asked cautiously, "Can I stay here after class?"
Lin Li suppressed a smile and said, "Of course, no one cares. It's fine to watch movies."
Ye Li asked Lin Li for a long time, and Lin Li told him to check the C language first, as C is the foundation of programming.But there is no C class in the freshman year.So Ye Li went to the library to borrow a book, and began to soak in the code composed of letters and numbers all day long.I was in the laboratory every day except for class. At the beginning, I went back to the night run at 9 o'clock, and then went back to the dormitory.After studying for a period of time, I found that there were more and more things I didn't understand. If this continues, there is still a long way to go before I can basically master the basics of programming.It is not easy for him to complete his usual study tasks, and he also has to do part-time jobs as a tutor and a supermarket, so he will not be able to find time all of a sudden.So starting from December, Ye Li changed the long-distance running to the 12:05 stall in the playground of the teaching area, and then stayed in the department hall at night until the lights were turned off at 30 o'clock before going back.Lin Li sometimes didn't come to the laboratory, and she would leave after 11:[-] pm, so Ye Li was often alone in the room, and she was quiet.
Ye Li and Lin Li's house has nothing but four sets of tables and chairs.Ye Li was here all day, and once saw the cleaning aunt in the corridor, because he saw that there were green plants in other offices, so he asked casually if there were any green plants to display.Auntie said that there are green radish, anthurium and monstera.He said he wanted two pots.Aunt Cleaning said "Yes, water yourself".
The next day she really pulled the cart and got some pots of flowers.As soon as Ye Li put it in the room, he immediately felt much more comfortable.In the past, Ye Li's grandfather liked to grow flowers very much. In summer, the yard was like a garden. In winter, the house was filled with flowerpots of all sizes, and it was very cramped to walk.But Ye Li's childhood memories are all green because of this.Later, when my grandfather passed away, the habit of growing flowers was carried on by him.The green plants brought here are the best things to grow. The pothos and the monstera are not blooming, but two flower buds have emerged from the two pots of anthurium.
There are usually no people in the department hall at night, but the lights will not be turned off and the doors will be locked.After 6 o'clock in the evening, it was completely dark.In the entire four-story corridor, only two or three houses were still lit.Tong Yan went on a business trip for two weeks at the end of November and just came back this week.On the first day back, after dinner, I found that the light was on in the room diagonally opposite the door.Normally, Lin Li is rarely caught. How can she still be in the department so late?
Tong Yan walked to the door and saw Ye Li lying on the table reading a book.The computer screen has a pure blue background, with half a screen of code written on it, and the cursor keeps blinking at the end.
He deliberately made his steps a little louder, and walked behind Ye Li.
"Teacher Tong, are you back?"
Tong Yan let out a "huh" and said, "Have you left yet?"
He glanced at Ye Li's screen, which involved pointers and bsearch functions, it seemed that he had learned a lot by himself.
"Is there a problem?" he asked.
Ye Li hesitated for a moment: "No."
Tong Yangang saw him holding the pen in his mouth, and knew that he must have a lot of questions, but he was too embarrassed to ask.
Tong Yan nodded, and saw Ye Li's mobile phone on the table, it was very old, very old style, and it was covered with an ugly transparent plastic case, the color of the plastic was yellowed.
He straightened up, only to realize that there were many more plants in the room.
"You did this?"
"The property management needs it." Ye Li said, "Can I bring you two pots?"
"You keep it. I've raised several pots to death." Tong Yan turned and walked out.
For several days, Ye Li didn't leave the department hall until after ten o'clock.In the past, Tong Yan was the only person on the entire floor at night, but now there is one more person diagonally opposite the door.The lights of the two houses shone in the corridor through the half-closed door, which seemed to be accompanied.But Tong Yan never asked him about his progress.Ye Li was actually still reading, and hadn't made any progress at all.
A few days later, two bright red flowers sprang out from the two pots of anthurium.Ye Li moved one of the pots and brought it to Tong Yan's office.
Tong Yan was talking to a teacher, glanced at Ye Li, and ignored him.Seeing that his desk was covered with blankets, Ye Li had no choice but to put the flowers on the window sill.
That afternoon, Ye Li was looking at the code on the computer when Tong Yan walked in suddenly and saw a piece of paper on Ye Li's desk with a circuit diagram drawn on it, so he picked it up and looked at it.
"Lin Li painted it for you?"
"Ah."
As for the test circuit of the chip, Ye Li hadn't started learning circuits this semester, so he had no clue.I want to ask Tong Yan, but I feel that I can't ask. I still want to look at the circuit before asking.Lin Li took the time to draw a sketch for him.
Tong Yan picked up the pen, added a resistor, a diode, and a timing module to it, and then put the paper on the table.
"Do it this way, first make the board."
"Oh."
Seeing his bewildered expression, Tong Yan comforted him and said, "If you don't understand, read it slowly."
He looked at Ye Li's screen again and asked, "Is there a problem?"
Ye Li has spent three hours in this program today, he gritted his teeth and said, "Yes."
"what is the problem?"
Ye Li took a breath: "I don't know, the result is wrong."
"stand up."
Ye Li realized that he was sitting, so he quickly stood up and gave Tong Yan his chair.
Ye Li compiled a typical test program, including some basic instruction sets of ARM. There are about 100 lines of the program, and the output results are always wrong.
Tong Yan glanced at it twice, got up and went to the house to get a book back, and sat down to read it again.Ye Li saw that the book over there was called "ARM9 System Design and Development".He estimated that Tong Yan might not be familiar with the specific instructions. After all, a teacher has many research directions. Tong Yan has mainly been doing drone control in the past two years, and it seems that Lin Li has only tried to get involved with ARM.
Tong Yan puts his right hand on the arrow keys on the keyboard, moves the cursor to the first line of the program, presses the down arrow key, and looks down line by line.
He saw the reading part of the stack in the middle, stopped to flip through the book, and moved the cursor up and down.
Tong Yan watched for 10 minutes without speaking.Ye Li didn't dare to show his anger, he didn't know if Tong Yan could see what was wrong, and how long it would take to see it.He glanced at his phone, it was already 05:30.
Tong Yan was really not familiar with this set of instructions, and repeated the grammatical format of the instructions over and over again.
"StakckIrq contains the address of the top of the stack," Tong Yan pointed to a line of syntax in the book "
"Here?" Tong Yan saw Ye Li enter the door, and stopped what he was doing, "Wait a minute, I'll go find Lin Li."
Ye Li stood in the room, looking around.It's the end of November, and the school has started to heat up.Although this department building has been built for a few years, Tong Yan's office is in the shade, the lighting is not good, the temperature is low, and unlike other houses, there are many flowers and green plants.Tong Yan doesn't seem to care much about his working environment, and he has a strong endurance.Wear long-sleeved shirts in summer, and just an extra top in winter.
