Reborn not to be a beast of burden, I set the rules.

"I've studied it." Shen Zhiyi opened her notebook, her fingertip pointing to the densely packed notes.

"The performance of the 4020 is not enough. After switching to the 6200, the peripheral circuitry needs to be redesigned."

Serial port, VGA, buzzer and other such devices are all unnecessary and can all be removed.

All physical buttons were removed, leaving only the power indicator light.

Keep the LCD controller and I2C connection for capacitive touch. I've looked at Atmel's solution, which uses QTouch charge transfer detection. It has good anti-interference capabilities and supports glass panels several millimeters thick.

She paused for a moment, then continued, "At the system level, I plan to customize Android myself."

Android's Java Virtual Machine is inherently resource-intensive, and it must be optimized to run on embedded devices.

Cut as many startup services as possible, adjust memory management, and reduce GC frequency. I've read some information suggesting that using native methods instead of Java loops can be 10 to 100 times faster.

Also, when accessing properties, you can't always use getters; accessing local variables directly is more efficient.

There was a few seconds of silence on the other end of the phone.

When Shi Xinglong's voice rang out again, it carried a hint of amusement: "You've done your homework quite thoroughly."

Shen Zhiyi paused for a moment, then remained silent.

"Have you considered capacitive touch solutions?" Shih Hsing-lung asked. "How do you plan to implement Atmel's solution?"

"Electrode patterns are etched using copper foil," Shen Zhiyi said. "They are then bonded to the back of the glass panel. The touch chip uses the FT5206, which connects to the main controller via an I2C interface. The calibration algorithm can be written by ourselves, referencing ANSI C touch screen drivers."

Shi Xinglong was silent for a moment, then asked, "What about the outer shell? What are your plans?"

"The acrylic sheets are hand-cut and hot-bent," Shen Zhiyi said. "The thickness is controlled to within 12 millimeters, and the back panel is sprayed with pearlescent paint to make it look cleaner."

There was a two-second silence on the other end of the phone, followed by a soft chuckle.

"Zhiyi," Shi Xinglong said, "to be honest, your plan is quite difficult to implement."

The 6200 is a chip designed by our ASIC center. Although its performance is stronger than the 4020, there are no ready-made mobile phone solutions on the market to refer to, so you have to figure everything out yourself.

Touchscreen controls, power management, system customization—every step is a potential pitfall.

Shen Zhiyi's heart tightened.

"However," Shi Xinglong changed the subject, "you've considered all these issues. You've thought about simplifying the peripheral circuitry, the touch control scheme, system optimization, and even how to make the casing. This shows that you didn't just come up with these ideas on a whim; you've really put in the effort."

Shen Zhiyi gripped her phone tightly and remained silent.

"The competition rules do stipulate that the 4020 chip must be used," Shih Hsing-lung continued, "but if you can develop this solution, you can submit it to the organizing committee as an optional project. The 6200 is a chip we developed ourselves. The fact that you can run a decent system on it is an achievement in itself. Not to mention that you have also considered touch control, appearance, and user experience, which is already a complete product mindset."

He paused, his tone earnest: "I'll talk to the organizing committee. As long as you can do it, the judges won't make things difficult for you. As for the practical pitfalls... come to me anytime you encounter them, and we'll figure them out together."

Shen Zhiyi was taken aback for a moment, then a warm feeling welled up inside her: "Thank you, Teacher Shi."

"By the way," Shi Xinglong suddenly asked, "Are you doing this all by yourself? Aren't you going to hire some help?"

Shen Zhiyi paused, then said softly, "Try it yourself first, and only ask for help if it really doesn't work."

Shi Xinglong didn't ask any further questions, simply saying, "Okay, as long as you know what you're doing. Go ahead and do it."

After hanging up the phone, Shen Zhiyi stared blankly at her phone screen for a while.

It's not that we haven't considered asking for help. Professor Shi's lab has several senior students who are quite skilled.

My good friend Lin Nuan, who shares a dorm room with me, is also quite skilled in practical skills, even though she studies communications.

But she didn't want to tell anyone about this project, including Lin Nuan.

What if we can't make it?

She bit her lip, suppressing the thought.

Open the competition registration system, log in, find the registration form you submitted earlier, and click to edit it.

Project Title: Portable Smart Terminal Based on SEP6200

In the team member section, only my own name was filled in.

Project Description: Based on the SEP6200 platform, design a prototype smartphone with no physical buttons and using capacitive touchscreen.

Preliminary plan: Simplify development board peripherals, build custom capacitive button circuit, handcraft acrylic casing, and deeply customize the Android system.

I checked it once, saved it, and submitted it.

A message popped up on the screen saying "Submission successful".

The night was deep outside the window, and all was quiet outside the laboratory building. She stared at the notification for a long time, then let out a soft breath.

It wasn't for the sake of the competition.

It was for him.

She glanced down at her phone again and opened her chat window with Ye Ming.

The last time we spoke was at noon.

She typed a few words, then deleted them. She typed again, then deleted again.

The last thing I sent was: "Remember to apply that ointment today. The wound on your back hasn't healed yet."

After sending the message, she placed her phone face down on the table and didn't look at it again.

He stood up, took off his white coat, and hung it on the hanger next to him.

The dark blue sweater underneath gleamed softly under the fluorescent light.

She packed her things, carefully put the draft paper and schematic diagram into her schoolbag, and turned off the light on the lab bench.

The corridor was dark, with only the emergency lights emitting a faint green glow.

She walked quickly, still carrying the faint scent of pine from the laboratory.

As she stepped out of the laboratory building, the moonlight rushed towards her, its silvery light falling on her shoulders and following her all the way back to her dormitory.

The dormitory lights were already off. She tiptoed upstairs and pushed open the door to her room.

Lin Nuan was already asleep, her breathing even. Moonlight filtered through the gaps in the curtains, falling on the edge of her bed.

She lay down, staring at the moonlight, her mind still replaying the lines on that draft paper.

He slowly closed his eyes.

Under the same moonlight, Ruan Xing was still awake.

She lay in bed, staring at the ceiling, her mind a jumble of thoughts.

This afternoon in the computer lab, the image of her staring blankly at the empty document resurfaced. Everyone else could write so smoothly, but she couldn't.

Although Ye Ming said, "The logistics minister is in your hands," she still felt a little uncomfortable.

There's always tomorrow.

Ye Ming agreed to go with her to ask for the money back, but could they really get that five thousand yuan back?

She took out her phone, sent two messages to Ye Ming, and then placed the phone next to her pillow.

I closed my eyes and felt a little more at ease.

Moonlight filtered through the gaps in the curtains, falling on the edge of the bed, white as frost.

Xu Wei, however, kept her eyes open.

The girls' dormitory lights were already off, and it was so quiet that you could hear your roommates breathing.

She stared at the moonlight, her eyes bright, showing no signs of sleepiness.

Lin Zhixia, lying opposite her, turned over and asked sleepily, "Why aren't you asleep yet?"

Xu Wei didn't say anything.

Lin Zhixia became a little more awake and lowered her voice: "I haven't seen you all day, what have you been up to?"

Xu Wei turned over to face her and whispered, "In the computer lab of the Computer Association, help Ye Ming and the others make a game."
