在keil编辑环境下完成了等精度脉冲宽度（时间间隔）的测量，该程序的硬件平台是用at89C52单片机和CPLD（epm7128slc84）以及液晶组成(The keil completed the editing environment such as precision pulse width (time interval) measurements, the program' s hardware platform is at89C52 MCU and CPLD (epm7128slc84), as well as liquid crystal composition)

一种占用很少资源的多事件操作系统，应用在M128上，极容易扩展到其他微控制器(A few more resources occupied events in M128 operating systems, applications, extremely easy to expand to other micro controller)

实现蜂鸣器驱动，蜂鸣器应用。非常好的实例。(Buzzer driver, buzzer application. Very good examples.)

0.2通道180°相位差方波，3通道120°相位差方波，4通道90°相位差方波 1.试验平台stm32f103c8t6 2.2通道用定时器3的1、2通道；3通道用定时器3的1、2、3通道；4通道用定时器3的1、2、3、4通道； 3.实现方法，周期和占空比用捕获通道中断反复修改捕获值来实现 4.相位差采用定时器的生效同步规则来实现（下一次更新时间生效）(0.2 channel 180 degree phase difference square wave, 3 channel 120 degree phase difference square wave and 4 channel 90 degree phase difference square wave 1. Test platform stm32f103c8t6 2.2 channels use 1, 2 channels of timer 3; 3 channels use 1, 2, 3 channels of timer 3; 4 channels use 1, 2, 3, 4 channels of timer 3; 3. Realization method, period and duty cycle are realized by repeatedly modifying capture value with capture channel interrupt 4. The phase difference is realized by the effective synchronization rule of the timer (the next update time takes effect))

说明：  这是一种基于STM32系统的红外光通信装置(This is an infrared optical communication device based on STM32.)
