Liu Chen said categorically: "No, now countless small companies have begun to play the idea of MP3, Kang Wenbin's sentence is right, as long as the chip is good, the technical content of MP3 itself is not high, but the price cannot be lowered, the interest space is small, it is not competitive, it is difficult to survive, the time is very urgent, and it must be listed as soon as possible." Pen "Fun" Pavilion www.biquge.info"

"Are you sure?"

Actually, I've been preparing for a long time, and this is a steady opportunity to make a fortune, so I'll take you with me. ”

Lan Jun felt that it sounded a little strange, and in the morning he was still talking about bringing others to make a fortune, and it was reversed so quickly.

"But I can't seem to do anything but make some money, so you can do it yourself. ”

Liu Chen looked at him seriously and said, "You are very important, and you need to do a lot of work." ”

This sentence is more than 10% profit for Lan Jun, he is still happy, this gentleman has no shortage of money in his family, and he comes out to prove himself, and the other is to spend money freely, and he is recognized by Liu Chen, who thinks he is a great talent, and he is very excited all of a sudden.

"Okay, done, I'll go register the company now, and if there's anything I can do, just ask. ”

"The name of the company is Soundmaster, and since we want to do it, we want to be the overlord of the digital music playback industry. ”

"I like the name, but what else?"

"I believe you can find a relationship to register as soon as possible, and then fly to the deep city immediately, purchase 128MB flash memory, and sigmatel chips, just 400,000 funds, I need you to buy back at the lowest possible price, as much as possible, I believe that your ability is no problem, BMW7 car keys or those palmistry skills can be used." ”

Lan Jun sneered, "You guy! Okay, I'm good at this job, I heard a lot of things from Kang boy just now, I almost hit my head against the wall, okay, I'll do it." ”

"Also, the shape of MP3, you can directly find a manufacturer to use a public model, and then open a mold is not necessary, and waste time and money, remember to let them print our logo, sound master, the pattern is the outline of an ear, I have registered the trademark in advance, and the relevant patents have also applied for several, or that sentence, the funds are 400,000, not enough to figure out their own way. ”

Lan Jun looked at Liu Chen's eyes and was about to worship, it seems that people are indeed prepared, so they will do it immediately, thoughtful, they really don't need to use their brains to work for Liu Chen, he loves to do this work.

Liu Chen found that he was excited, sure enough, the money was too little and he didn't feel it, he promised Lan Jun to earn 600,000 yuan, it was definitely not a fool, it was absolutely okay to do well, then he could earn three million, with this money, it would feel different, and he was also a little confident in Jianghai.

In college, you can be happy and carefree to talk about love with Zhuo Ling.

Lan Jun had long since run away, his high-efficiency personality was appreciated by Liu Chen, he calmed down and turned back to the laboratory.

His battlefield is here, solving technical problems.

Kang Wenbin saw Liu Chen coming back and said with a smile: "Heh, I thought you ran away, but you really dare to come back." ”

"As long as you help me, the cost of 10,000 yuan will be yours. ”

The faces of the three guys are all happy, Lan Jun is indeed very generous, and he gave the money directly, but this job is not easy to do, he is tired to death in the past few days of collecting data and analyzing it, and there are still 108,000 miles to make the product below.

Kang Wenbin was a little older, and asked his cousin Kang Wencheng, "Can he call the shots in this matter?"

Kang Wencheng was very shy and didn't know what to say.

Liu Chen said firmly: "I can naturally call the shots, Wen Cheng, Mr. Lan has gone out to do errands, let you stay here for the next few days, and you are mainly responsible for buying us food." ”

As he spoke, he gave him a few hundred dollars.

"Let's get started, two and a half days to get the first demo out. ”

Kang Wenbin said: "Let's talk about it first, in the past two and a half days, whether you can figure it out or not, the 10,000 yuan will belong to us, in black and white, you write it down." ”

Liu Chen wrote a note to them, and it was really not worth so much money for a few of them to help, but this ready-made laboratory, complete equipment, and free to use, helped a lot.

"Is there a ready-made development board for the Sigmatel chip?"

"Nope!"

Liu Chen sat directly in front of the computer that opened the Protel interface, and quickly drew a chip debugging PCB, because there was no need to consider the layout and size, it was drawn in ten minutes.

Although it was very simple, but when the PCB came out of the board-making machine, Kang Wenbin and the two undergraduates still felt a little unreal.

Kang Wenbin said: "Don't you even look at STMP3410's datasheet?"

Liu Chen said with a smile: "When you have seen the datasheet of thousands of ICs and designed ten ICs using FPGAs, you will know that the external pins are nothing more than that." ”

Kang Wenbin opened his mouth, thousands of ICs, FPGA as IC, he suddenly felt that the guy in front of him who looked very young was not simple, and his contemptuous heart was taken back, and he took the board and said: "I'll go to the electronics market to find someone to solder the chip." ”

Liu Chen had already sat down on the soldering iron and said, "Don't bother, I'll solder." ”

This is the IC of the SMD SOC cover, and it is very difficult to solder, Kang Wenbin blurted out: "You can also weld the SMD?"

Oh, I have welded both the FPGA and DSP28 series, and this piece is only a few feet, Liu Chen replied casually: "I have welded a few times." ”

"But the oblique mouth of our soldering iron is too thick, and the chip pins will stick when you click it lightly, and the chip may be broken when the heat gun blows. ”

Liu Chen didn't speak, and he had to speak obliquely to solder the chip with this kind of pin.

Focused and meticulous.

Holding the soldering iron in one hand, click on the rosin, puff up a burst of white smoke, and carefully align the chip with the solder joints on the PCB with the other straight hand.

Then, the other three sides are also brushed.

Liu Chen picked it up and looked at the light, waved it, and then handed it to Kang Wenbin and ordered, "Test the pin connection." ”

Kang Wenbin and the two undergraduates were stunned, this is the same as a martial arts master, and it can be done with three or two clicks.

This welding component is more like a handiwork, it can't be faked, the three of them mechanically obey, do a good job of laying down the hands, and test it in the past.

Liu Chen turned on another computer and began to write algorithms.

A few minutes later, Kang Wenbin said: "The test is complete, every pin is soldered, and there is no short circuit." ”

There was a lot of admiration in the tone.

"The circuit diagram is on that computer, can the chip capacitors, resistors, and inductors be soldered?"

"I can weld this. ”

"Then solder all the other devices, then plug in the power supply, check the power on of the chip, and then find an ordinary headset to come over, and I will write the algorithm and transplant it in. ”

Several students were already completely convinced and fully cooperated.

Why are there so many fewer recommendation votes all of a sudden, brothers! The fat man is going to cry.
