ADC0809进行AD采集电压测量

16位AD转换器mcp3421读写时序例程，c51代码，稍作修改可以移植到其他单片机使用(16-bit AD converter timing mcp3421 to read and write routines with C51.)

能在LCD1602上显示年月日时分秒，采用时钟芯片进行断电保存，拥有闹钟设置功能。(Can display the date when in LCD1602, using the clock chip to save power, with alarm function.)

说明：  智能台灯可以根据光照的亮度自动调节亮度，可以保护大人和孩子的视力。(Intelligent desk lamp can automatically adjust the brightness according to the brightness of light, which can protect the eyes of adults and children.)

采用STC12C5A60S2单片机发生47KHZ的PWM脉冲信号，经过IR2104控制MOS，从而控制整个BUCK电路。单片机内部自带的10位ADC能通过电压电流检测电流实时反馈电流和电压数值，并由此调整输出的PWM的占空比，形成电流电压闭环控制系统。按键能设置输出电流从0.2A到2A，以0.01A递增，输出最大10V，液晶能显示实时输出电流与电压(use STC controller to generate pwm signal ，whic can dribe mos pipe，then control buck circuit)

CC2530,通过PWM调光，实现LED灯由亮变暗，由暗变亮，不断变化，基于IAR编译。(CC2530, by PWM dimming, LED lights achieve the light dimmed by the dark to light, constantly changing, based on the IAR compiler.)

说明：  This is HC-05 Bluetooth module information

基于51单片机的IIC总线的C语言编程，通过51单片机来模拟IIC总线协议(Based on 51 MCU IIC C language programming bus by the microcontroller 51 to simulate the IIC bus protocol)

非常实用的STC15W4K32S4小程序，采集32个AD数据进行求平均值，LCD12864显示AD采集程序(The very practical STC15W4K32S4 program, which collects 32 AD data for the average, LCD12864 shows the AD collection program )

ucOS+ucGUI 人机界面实验源码,采用STM32单片机(ucOS+ucGUI project source code)

飞机的设计和制造一直是与性能优异的材料 联系在一起。20世纪60年代中期以碳纤维为增强体 的复合材料问世，70年代初开始应用于军用飞机 结构，80年代开始应用于民用飞机结构。复合材料 具有比强度高和比刚度高的独特优点，飞机结构 采用复合材料，其重量可相应减少20%~30%[1]。此 外，复合材料还具有可设计性强、疲劳性能好、耐 腐蚀、易于大面积整体成型、维护性好等优点。目 前，复合材料已经成为重要的飞机结构材料。(he design and manufacture of aircraft has been a material with excellent performance Relate. In the mid 1960s, carbon fibers were used as reinforcements The composite material came out and was used in military aircraft in the early 70s The structure began to be applied to civil aircraft structures in 80s. Compound material The aircraft structure has the unique advantages of high specific strength and high specific stiffness The weight of the composites can be reduced by 20%~30%[1] accordingly. this Besides, the composite material has the advantages of good design, good fatigue performance and good resistance to fatigue Corrosion, easy to form a large area, good maintainability and so on. order Before, composite materials have become important aircraft structural materials.)
