这是一个判断某一年是否为润年的程序，运行可执行程序Ifleap.exe后，输入具体的年份， 可输出是本年是否为闰年的提示信息。-This is a judgment of whether a particular year Runnian procedures, Ifleap.exe running executable, the importation of specific years, output this year is a leap year if the message.

从输入文件如in.txt读取数据，经com1端口发送（自发自收），收到的内容存入输出文件如out.txt。 在按键后启动发送，并开始计时，发送完毕后，结束计时，并显示发送所花时间。

本应用为温度计的源程式,用C写的,不错哦-This application for thermometer source programs, written using C, yes Oh

PWM控制电机,编辑控制方式。在这个DEMO里建了一个函数F_Pwm(int a,int b) 用于PWM设置，传入两个参数第一个用于频率设置，第二个用于占空比设置。另外还开了外部中断可进行频率和占空比的步进，从而达到调整速度的目的-PWM motor control, edit control mode. In this DEMO was built inside a function F_Pwm (int a, int b) for the PWM settings, with two arguments the first one for the frequency setting, the second set for the duty cycle. It also opened the external interrupt can be the stepping frequency and duty cycle to achieve the purpose of adjusting the speed of
