PWM

DDS9850，亲测可用，有中文解释，信号发生器(DDS9850, pro-test is available, there are Chinese explanation, the signal generator)

99秒马表，在Proteus设计两个数码管动态显示及一个键盘SP。在ucos下结合keil完成开始时，显示“00”，第1次按下SP后就开始计时。 第2次按SP后，计时停止。第3次按SP后，计时归零。 (99 seconds stopwatch, two in the Proteus design dynamic digital tube display and a keyboard SP. Keil in combination ucos completed under the beginning of the show " 00" , 1st timer after pressing the SP. 2nd by SP, the time to stop. The 3rd by the SP, the time zero.)

基于51单片机的数字电子秤，有文档的详细说明(A digital electronic scale based on 51 single chip microcomputer with detailed description of the document)

设计并制作一个功率可程控的高效率音频功率放大器及其参数的测量、显示装置。功率放大器的电源电压为+12V（电路其他部分的电源电压不限），负载为8Ω电阻。(Audio amplifier)

ADS 0.18um library which have all kind of mosfet you need

这是一个自制万年历的显示程序。能显示温度日期时间等。。。。。。(This is a homemade calendar display program. Can display the temperature of the date and time. . . . . .)

DS1302+DS18B20+无线遥控应用程序(DS1302+ DS18B20+ wireless remote control applications)

定时器：设定时间格式（00：:00）后，到时间弹出提示(timer：set time(00:00),then run up)

基于ARM的俄罗斯方块设计，本次将设计实现一个用C语言编写的、在基于ARM核心的ADuC7020 ARM开发板上实现的单机版的俄罗斯方块小游戏。使用Keil3编程软件对C语言代码进行编写，支持按键操作，在实现过程中涉及了LCD液晶屏的图形显示、按键控制、LED控制、中断、蜂鸣器等嵌入式的编程技术。(Tetris ARM-based design, this will be designed to achieve a C language, the ADuC7020 ARM development board ARM core-based implementations of stand-alone version of the Tetris game. Use Keil3 programming software code written in the C language, support for key operations involved in the implementation process of the LCD screen graphical display, control buttons, LED control, interrupt, buzzer embedded programming techniques.)

基于K60的PID调速，飞思卡尔都要用到，很重要的(K60 is based PID control, Freescale must be used, it is important)
