After Zhang Sanshi finished speaking, not only the other directors, as well as the two directors Zhang Min and Jiang Ning, but even the people in the hardware department couldn't help but prick up their ears, they wanted to hear what hardware problems the director of the software department wanted to ask. Pen % fun % Pavilion www.biquge.info

Although on the surface, it was the other party who asked Jiang Ning about the hardware problem, in fact, everyone knows that this is the director of the software department who came to pick the scene, as the director of the software department, came to the hardware department and asked Jiang Ning about the hardware problem, this is simply Chiguoguo's move of not taking Jiang Ning in his eyes and wanting to slap him in the face, which is tantamount to being bullied by others!

If Jiang Ning can't answer, or even answer imperfectly, in front of so many people, where will he put his face? What kind of face does he, the newly appointed deputy director of the R&D department, have to speak of?

Shen Jia, Cao Jianwei, Liu Yunlong and several other colleagues who have a very good relationship with Jiang Ning couldn't help but sweat for Jiang Ning, and hated Zhang Sanshi, the director of the software department who came to the door.

However, no matter how much they hate each other, in such a situation, it is useless at all, people are openly and honestly 'consulting' with you, a 'hardware genius', you can't even have the courage to answer, right? In that case, Jiang Ning's face will have no place to put it.

So, everyone had to hope that Jiang Ning could answer each other's questions.

"Huh...... Deputy Director Jiang, the first question I want to ask is...... What is a pull-up resistor?"

Software director Zhang Sanshi looked at Jiang Ning with a smile and asked.

Pull-up resistor!

Hearing this word, Shen Jia, Liu Yunlong and several other sketchboard engineers couldn't help but look at each other, although they deal with components all day long, but, what is this 'pull-up resistor' is really the first time to hear, this is not to say that they are lonely and unheard, but, this name is really not what they can hear on a daily basis as drawing board engineers!

Because, this is a technical term related to software drivers!

For this term, hardware engineers who often deal with software engineers still know it, but Jiang Ning, who started as a 'sketchboard engineer' and is completely halfway out of the house in terms of hardware, can you answer it?

Cao Jianwei and even Bi Zhonghua on the side couldn't help but be secretly worried in their hearts.

It's not that Cao Jianwei doesn't believe Jiang Ning, but the software director Zhang Sanshi's question is too biased, it's not that they are hardware engineers who have worked for several years, even if they answer, most of the answers are unsatisfactory, and Jiang Ning, a student who has just graduated from school for a year, how could he be exposed to such a professional vocabulary?

Zhang Min on the other side couldn't help but raise her eyebrows slightly, she could naturally answer this question, but her little boyfriend Jiang Ning, can she say it?

Zhang Chenglin, the maintenance supervisor, and Wu Xiaowei, the structural supervisor, although they didn't know much about the pull-up resistor, but seeing that many people in the hardware department were worried, they knew that Zhang Sanshi's question was definitely not simple, and it was not so easy for Jiang Ning to answer it.

So, the maintenance supervisor Zhang Chenglin couldn't help but show a smug look, and although Wu Xiaowei, the director of the structure department, did not show anything on the surface, he was also happy in his heart, he was also happy to be able to kill the majesty of the deputy director who came out of nowhere, of course, the most important thing is that he doesn't have to take the blame, this is completely the software director's side of the difficulty.

At this moment, Zhang Sanshi, the software director, didn't think about it so much, he was very satisfied with the first question he asked, although this question is related to the software driver, but as a qualified hardware engineer, the concept of the pull-up resistor, must also be to know, or how to cooperate with the software driver engineer to debug the circuit board?

Therefore, asking this question not only ensures great difficulty, but also makes others unable to say anything, because if this is strictly speaking, it is indeed a hardware problem.

Zhang Sanshi, the software director, couldn't help but slightly upturn the corners of his mouth, looked at Jiang Ning, and said: "Deputy director, I think, you are extremely professional in hardware, you won't know this word, right? ”

In Zhang Sanshi's opinion, Jiang Ning, who has only graduated for one year and is estimated to have never met with a software engineer, how can he know such a professional vocabulary? So he waited for the moment when Jiang Ning couldn't answer and made a fool......

However, what surprised Zhang Sanshi a little was that when he looked at Jiang Ning, he found that the other party's face did not have the negative expressions of doubt, hesitation and even anger that he imagined, but was still the same as just now, with a breezy and calm face......

"Brother Sanshi, what should I be, it turned out to be a pull-up resistor, this problem, I happen to really know something, the so-called pull-up resistor, is to increase the 'driving ability' and add a high level on the signal line, this high level and the signal line has a current limiting resistor, and this current limiting resistance is called a pull-up resistor. ”

"Several commonly used values of pull-up resistors are, 1K ohms, 4.7K ohms, 5.4K ohms, and even 10K ohms. ”

"Well, as far as I know, this pull-up resistor is generally used when debugging I2C signals or differential signals, which has a great relationship with software drivers, Brother Sanshi, as a software director, you don't even know the most basic professional vocabulary in software drivers, right?"

Speaking of this, Jiang Ning looked in disbelief.

Jiang Ning, this rabbit cub can pretend to be thirteen better than me!

At this moment, Zhang Sanshi, the software director, couldn't help but slander in his heart, he felt that his face was a little hot, he wanted to embarrass Jiang Ning with this question, and when the other party couldn't answer, he pretended to teach the other party a few words.

Where did I think, the other party not only gave a perfect answer, but also threw the pot on himself in the end, pointing out that this question is more inclined to the software driver, which can't help but make him, the director of the software department, a little embarrassed.

You, a dignified software director, took a problem that was greatly related to software drivers, ran to Jiang Ning, who was born in hardware, and said unashamedly to ask the other party a hardware problem.
