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))

单片机通过PWM输出供电，驱动3个串联电阻，其中50K是一个电位器，人为不断的旋动电位器，来模拟负载无规律的变化。 目标要求：100uF电容两端的电压不受负载的影响，即ADC读数要求稳定在100左右。 大概的输出电压mV = 5000mV * ADC读数 / 255 调整 P、I、D 这三个系数，还有调整间隔检测时间，即可调整负载电压的稳定度和皱纹度。 (单片机通过PWM输出供电，驱动3个串联电阻，其中50K是一个电位器，人为不断的旋动电位器，来模拟负载无规律的变化。 目标要求：100uF电容两端的电压不受负载的影响，即ADC读数要求稳定在100左右。 大概的输出电压mV = 5000mV* ADC读数/255 调整 P、I、D 这三个系数，还有调整间隔检测时间，即可调整负载电压的稳定度和皱纹度。 )

基于89C51的光照模块程序，用的器件是BH1750。比较有用(89C51-based lighting module program, with the device is BH1750. More useful)

此款用法同其他剥头皮一样，对点差要求高，平台相应速度要快(This EA is based on a variety of MT4 software, simple and practical)

S52三个定时器实现两路测速（测频）系统，一个定时器作时间基准，另外两个定时器作输入捕捉用，实现测频。(S52 3 Two Speed Timer (measuring frequency) system, a timer for a time basis, for the other two timers with input capture, to achieve frequency measurement.)
