The Crystal Circuit of 51 Single-Chip Computer
In the 51-bit single-chip computer, the crystal circuit was a crucial part of the peripheral circuit of the single-chip computer. From the perspective of pin connection, the 51 single-chip computer had two pins, XTAL1 and XTAL2, for connecting to the crystal oscillation (crystal resonant). These two pins were connected to an internal phase shifter of the MCUs to form a Pierce Oscillator with the external crystal oscillation. The working principle was that the Pierce Oscillator needed to meet the two conditions of 2k Pi loop phase shift and closed-loop gain of 1 in the ideal circuit form. The phase shifter provides a 180° phase shift for any frequency component and can be seen as a buffer. It is easy to obtain a loop gain of 1 by adjusting its output characteristics. However, this was not enough to start the vibration. The crystal itself was very important. Quartz crystals had a piezo electric effect. After processing, the Quartz Crystal Resonator (QCPR) could be represented by an ideal circuit model consisting of a L1 - C1 - R1 series resonant circuit plus a very small C0. The QPR was connected in parallel with the phase shifter to act as a frequency selection network. When it was powered on, it could be seen as a step signal being input into the output of the phase shifter. The QPR picked out the signal at the resonance point frequency. When the loop gain was 1, the circuit tended to be stable. In the crystal circuit, the common crystal frequencies were 4, 8, 11.0592, 12, etc. The crystal was used to provide a stable clock signal for the single-chip computer. All the instructions of the single-chip computer were based on this. The speed of the single-chip processor was related to the clock frequency provided by the crystal. The higher the clock frequency, the faster the single-chip processor would run. From the composition of the crystal circuit, it was composed of a Quartz crystal and a circuit. Together with the reset circuit, it ensured the stable operation of the single-chip system. The main function of the crystal circuit was to provide clock signals for the operation of various modules within the single-chip computer to ensure the correct execution of the program.

A novel about the White Jade Pagoda
There was no reference material that specifically used the white jade tower as the theme of the novel. There was only a description of a character arriving at a white jade tower during the development of the plot in a fantasy novel, but it did not indicate that the white jade tower was a special creation based on the historical white jade tower. Therefore, it was difficult to pinpoint which novels were specifically about the White Jade Pagoda. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

A person's experience in racing 300 words
Running was a sport full of challenges and rewards. In the process of running, one must first understand their own physical condition. This was the foundation. Make a suitable training plan according to your own situation to avoid excessive burden. Secondly, the adjustment of mentality was crucial. Maintain patience and perseverance, overcome nervousness, and face it with a calm heart. Furthermore, using reasonable force was the key. It was easy to get tired if you used too much strength. Only by distributing strength and rhythm appropriately could you stabilize your long-distance running. In the face of fatigue and defeat, a firm belief could make one more confident and determined. Finally, he had to enjoy the entire process and the result of the race. It was not only a competition for ranking, but also an opportunity to feel the changes in one's body and gain inner peace. These experiences were precious treasures in life. Whether it's physical challenges or psychological growth, we get exercise and improvement in the race.

How to make a quick shot video
Here's how to make a fast-motion video in Coursemaker: 1. He opened the software and inserted the video that needed to be fast-paced. 2. He previewed the video and found the point where he wanted to make a quick shot. He then right-clicked on the time track to split the object. 3. After the division was completed, the two clips were separated on the time track to avoid incomplete shots due to insufficient time tracks when setting up fast shots. The distance could be maintained by dragging the clip. 4. He continued to find a splitting point on segment 2 and split it (the same method as above), then dragged it to maintain the distance. 5. On the time track, select clip 1 and right click to open the tool bar. Find the playback speed and set the speed to 2 (the higher the value, the faster the speed). 6. After connecting the three clips in time, the fast-motion video was completed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is it okay to write a novel of 100 words yourself?
Of course he could. Creating a novel was a creative activity. No matter the number of words, it could show the author's creativity, imagination, and ability to express himself. A 100-word novel belonged to the category of micro-novels or flash novels. It required concise language to construct the plot, shape the characters, and convey the theme. Although the number of words was limited, it could also write a wonderful story. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Why is Huang Qilin's birthday 1221?
His family had always celebrated his birthday on the 23rd of November according to the lunar calendar. Before his 16th birthday, he found out that the 23rd of November in the 2016 lunar calendar corresponded to the 21st of December in the solar calendar, so he thought that his birthday could also be on the 21st of December. Therefore, he had a birthday on the 21st of December. While waiting for the anime, you can also click on the link below to read the classic original work of The King's Avatar!
