Chapter 145 Manuscript

After Arthur helped Lin Hong kill the poison, he went back to his room, and Lin Hong also followed behind him, and took back two books from him, both of which were about infrared communication protocols, and a floppy disk, which was matched with one of the books, which contained some example codes of cases in the books.

Arthur was already very sleepy at the moment, he could no longer hold on, so he could only continue tomorrow during the day.

Lin Hong said that he came to help specify a communication protocol for the calculator, Arthur did not have much hope for this, in his opinion, Lin Hong did not even know what infrared communication was before, how could he develop such a protocol in a short period of time?

However, he did not dampen Lin Hong's enthusiasm, because some things cannot be learned a profound lesson without experiencing them personally, just like the previous poisoning, he did not specifically remind him to pay attention to it before, in his opinion, some things must be felt by himself.

However, Arthur didn't know that when Lin Hong said this, he actually had a certain degree of certainty, in his opinion, the communication protocol was not difficult, this was the feeling he got after reading the book on protocol. The first time he read it, he thoroughly understood the bottom of the agreement, which is the rules, the rules that people specify for the purpose of data exchange, and the various rules and regulations in ordinary life.

And Lin Hong also has a basic understanding of infrared communication from the posts he saw before. In his opinion, infrared communication and radio communication are completely interconnected, infrared also belongs to radio, and radio is his strength, he has read many professional books on this area a long time ago, although it is rarely used in later life, but those contents have been stored in his mind, not forgotten.

Infrared is a kind of invisible light, is the most common electromagnetic wave in life, in fact, all glowing objects, all the moments are emitting infrared rays. In Lin Hong's previous radio communication career, infrared rays appeared as interference radio waves, and they were not studied in depth. Unexpectedly, it turned out that someone used it as a data transmission very early on. However, due to the particularity of its wavelength, it can generally only be used for short-distance transmission, and cannot penetrate obstacles, and data transmission can only be carried out indoors.

After Lin Hong returned to his room, he did not immediately start researching infrared, but ran the email software and began to write the first email in his life.

Because he remembered that he had not yet contacted Lus, and that the other party had given him an email address before, so that since he could now access the Internet, he should send an email greeting to the other party, and by the way, ask how his operating system project is progressing.

When Lin Hong registered for "Tulip" BBS, he automatically got a free email address, and he used this email address to write to LUS at the moment.

After sending his first email, Lin Hong began to formally study infrared communication technology.

The infrared wavelength range is 0.70μm~1mm, but in this wavelength range, the stability of data transmission varies, and each manufacturer has its own understanding.

In fact, as long as the protocol is suitable and the hardware meets the conditions, the rate of infrared communication can also reach a very high rate, Lin Hong saw that there are already manufacturers who have reached more than 100kbits, and theoretically can reach higher speeds.

The infrared communication protocol actually has a lot of similarities with the communication protocol, and it is more streamlined than this protocol, and it also has to go through the process of encoding and decoding in the process of transmission. This part is the function of the hardware, Texas Instruments has done this part of the work well, Lin Hong has to do the work now, completely in the software, as long as the infrared encoding and decoding circuit on this calculator is combined, a set of communication protocols suitable for it can be customized.

The materials that Matthew had asked Texas Instruments to mail were now on Lin Hong's desk, and the circuit diagram of the infrared transceiver was inside.

Under the deliberately dimmed desk lamp, Lin Hong picked up the calculator reference materials for a while, picked up the book of communication protocols and turned a few pages, and then drew a few time sequence diagrams with a pencil on the white paper......

Time passes imperceptibly, the sun rises again in the east, and a new day has arrived.

※※※※※

On the branches of the trees by the lake, unknown birds are chirping happily, jumping around on the branches, savoring the umami and delicious breakfast.

Under the tree, Lin Hong, Arthur and Matthew were exercising in the morning.

"Arthur, are you sure we don't have to stand like Stone?".

Matthew, who was pressing his legs and twisting his waist, looked at Lin Hong, who was standing in a three-body pose not far away, and asked in a low voice.

"You can press your legs with peace of mind, we haven't reached the level of standing in the three-body pose yet." Arthur was simulating several common attacks in his mind at the moment, occasionally ducking his head and dodging, and then quickly counterattacking, as if there was an invisible invisible man in front of him fighting him.

"Three-asana?" The Matthew scholar Arthur's statement reluctantly repeats these three words in Chinese pronunciation.

"Yes, three-body pose, that's how Stone stands now." Arthur made a series of counterattack moves, and then stopped panting, "This is a basic skill, listening to stone, it is very complicated, you can't stand casually, otherwise you may have all kinds of unpredictable pain." ”

"Oh my God, thank you for the timely reminder!" Matthew was startled, he was already thinking about secretly contacting Lin Hong after he went back.

"It seems that I should follow Stone's advice and practice honestly. Using your brain to practice is really a magical way to practice. ”

Matthew honestly began to move his body according to the plan Lin Hong had specified before, although he had doubts, but after all, the living example was in front of his eyes, and he had to believe it. However, the feeling of morning exercise seems to be good, looking at the quiet and wide road, there is no figure in sight, most of his peers are lying in bed at the moment, only the three of them are working hard, so he has a psychological pleasure that is about to surpass others.

After the morning exercise, they went home.

Vina still prepared a hearty breakfast on time, looking at Arthur with a big appetite, her face showed a bright smile, Arthur used to rarely have such an appetite in the morning, and even often went to school without breakfast.

Moreover, it was also evident to her that Arthur was now beginning to have a smile and confidence on his face, which had rarely been seen before. These are all very gratifying changes, all of which happened after Lin Hong moved in, and it is obvious that these are all the credit of Lin Hong.

"Arthur, come to my room later, I've got something for you." After breakfast, Lin Hong whispered to Arthur.

Arthur immediately finished the cereal porridge in the bowl, and then followed Lin Hong to his room, he thought that it might be Lin Hong's computer problem again, and asked him for help.

After coming to the room, Lin Hong took out a stack of white paper from the table and handed it to him.

Arthur wondered, "What is this?" ”

"I've finished the first draft of the communication protocol, you can take a look at it and see if there are any changes that need to be made."

"What?" Arthur suspected that he had misheard.

"Let's take a look at it first, this is the result of my last night."

Arthur glanced at Lin Hong twice, took the manuscript in his hand and began to look at it quickly, these manuscript papers, with words, codes, and pictures, were very concise, and he read them quickly. There was a sense of déjà vu, but there were some innovations that he couldn't understand, but Arthur didn't feel how the manuscripts in his hand were at the moment, but he just felt that Lin Hong's efficiency was very high, and he actually made this so quickly.

"You didn't sleep all night last night?" Arthur looked at the manuscript paper in his hand, a whole stack, at least a dozen sheets, and it would take a long time to write it out by hand.

"Hey, I'm in good spirits, I just need a short amount of sleep." Lin Hong said very tactfully, "There is still room for improvement in some places, but the time is too rushed, you can make it first, and then optimize it." ”

Arthur nodded: "I'll take it to the school to take a closer look, and if you think it's okay, I'll go to the school computer room to test it and see if it works." ”

He didn't have much hope for it, what could he do in one night? What's more, when Lin Hong asked him for a book yesterday, it was already one or two o'clock in the morning, and at that time, Lin Hong didn't know anything about infrared communication.

What is the communication protocol? As far as he knows, due to the lack of a unified standard for infrared communication, there are many similar products with protocols on the market, which are incompatible with each other, and are only compatible with their own products, which are very confusing. A while ago, there seemed to be news that these manufacturers plan to sit together calmly and work together to formulate a unified standard, after all, this is the ultimate trend, just like the agreement, unified agreement, hello, I am good.

After all, Lin Hong is a kind-hearted person, and it is a very remarkable thing in itself to toss so many pieces of manuscript paper after working hard for one night, so although he doesn't think so, he will show enough respect. What's more, the reason why Lin Hong had to stay up late to make it can be said to be to help himself.

Pressed for time, Arthur copied all the programs he had written to a floppy disk, planning to go to the school computer room to continue to complete it when he had time.

After coming to school, Arthur's first class was a history class, and he was not interested in it, so he took out the manuscript that Lin Hong had given him and re-read it.
