PWM 控制 LED 灯渐亮渐灭程序 适用 ME300B 开发系统 利用定时器控制产生占空比可变的 PWM 波 按K1，PWM值增加，则占空比减小,LED 灯渐暗。 按K2，PWM值减小，则占空比增加,LED 灯渐亮。 当PWM值增加到最大值或减小到最小值时，蜂鸣器将报警。-PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.

此程序为KEIL环境下开发的代码（开发环境备选里没有KEIL），功能在成功运行后可以播放“生日快乐”歌。所需要的开发硬件为AT89C51为主芯片的单片机。-This program is developed under the code in KEIL environment (development environment, where there is no alternative KEIL), features a successful running play " Happy Birthday" song. Required the development of hardware-based chip microcontroller AT89C51.

本系统以AT89S52单片机为核心部件，外加温度采集电路、及显示电路和越限报警等电路。采用单总线型数字式的温度传感器DS18B20，使系统具有测温误差小、分辨率高、抗干扰能力强，动态显示的方式等特点。本设计既可以对当前温度进行检测又可以对温度进行数码显示，两位整数两位小数的显示方式具有更高的显示精度，若超越极限温度则触发蜂鸣器报警。利用功能强大的Keil和具有互动电路仿真的Proteus进行程序的编写和仿真。-The system AT89S52 microcontroller as its core components, plus the temperature acquisition circuit, and display circuitry, and the more limited alarm circuits. Single bus-type digital temperature sensor DS18B20, the system has a temperature measurement error of the small, high resolution, anti-interference ability, dynamic show the way and so on. This design not only can detect the current temperature can also right temperature digital display, two integers with two decimal places are displayed to show a higher precision, if the temperature is beyond the limits of buzzer alarm is triggered. Keil and the use of powerful interactive circuit simulation of the Proteus programming the preparation and simulation.
