dc-dc直流直流转换电路仿真，buck转换电路仿真(Dc- dc dc dc conversion circuit simulation, buck switching circuit simulation )

使用到蜂鸣器、Lcd1602、ZLG7289和串口，键盘实现加法器，控制LCD1602和蜂鸣器音乐播放。借助串口调试助手，可以用电脑发送字符，替代键盘，完成上述三种功能。(To use the buzzer, Lcd1602, ZLG7289 and serial port, a keyboard adder, and a buzzer control LCD1602 music player. With serial debugging assistant, a computer can send characters, instead of the keyboard, the above three functions.)

这是一个智能电压表的实例，里面有完整的程序。这个电压表可以数字显示电压值的大小。 (This is the example of a table of a smart voltage, which has a complete program. This digital voltmeter shows the size of the voltage value.)

硬件资源: 1,DS0(连接在PA8)，DS1(连接在PD2上) 2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3寸LCD模块(仅支持MCU屏) 4,按键KEY0(PC5)/KEY1(PA15)/KEY_UP(PA0,也称之为WK_UP) 实验现象: 通过按键KEY_UP可以控制定时器AutoReloadTimer_Handle的开启，这个是 周期定时器，一旦开启就会不断的运行，直到按下KEY1将其关闭。按下KEY0 可以打开定时器OneShotTimer_Handle，这是个单次定时器，只会运行一次， 运行周期到了以后就会停止运行，除非按下按键KEY0将其再次开启。(Hardware resources: 1, DS0 (connected to PA8), DS1 (connected to PD2) 2. Serial port 1 (baud rate: 115200, PA9/PA10 connected on board USB to serial chip CH340) 3, ALIENTEK 2.8/3.5/4.3 inch LCD module (only supporting MCU screen) 4. Keyboard KEY0 (PC5)/KEY1 (PA15)/KEY_UP (PA0, also known as WK_UP) Experimental phenomena: The timer AutoReloadTimer_Handle can be turned on by keying KEY_UP. This is The periodic timer will run continuously once it is turned on until KEY1 is pressed to turn it off. Press KEY0 You can turn on the timer OneShotTimer_Handle, which is a single timer and only runs once. The run cycle will stop after that unless KEY0 is pressed to turn it on again.)

这是一本超声波2级考证的一本书，也是超声波专业学习者和研究者的基础书籍，很实用的。(This is a book about the ultrasonic level 2, and it is also the basis of learners of ultrasonic professional and researchers books, very practical.)
