实现一个电池测试系统,用于对电池的充放电情况进行检测。(The realization of a battery test system for charging and discharging of the battery were detected.)

说明：  带中断输出功能的时钟芯片例程序,可移值，编译！(With interruption of the clock chip output function Example procedures, can shift the value, the compiler!)

介绍如何简单可靠而方便测量 4～20mA 信号的文章。许多仪器仪表在远距离传送信号时，都有可能采取 4～20mA 的方式进行传送。本文对使用运算放大器或者不用运算放大器的场合都有介绍。给出了接口电阻的计算方法以及调整4mA＝零点，20mA＝满度的详细说明。并附有局部连接的原理图。(How simple, reliable and convenient measurement of 4 ~ 20mA signal article. Many instruments in the long-distance signal transmission, may take 4 ~ 20mA way transmission. In this paper, an operational amplifier or op amp do not have a description occasions. Shows the calculation of the interface resistance and adjust the 4mA = zero, 20mA = full scale details. Local connections together with the schematic.)

说明：  89C52 TTP224N 触控定时器中断PWM调光(Touch timer interrupt PWM dimming)

说明：  stm32f7采集一遍往外打点一遍用AD采点然后将采样值返回给电脑(Stm32f7 collects points from outside once, uses AD to collect points, and then returns the sampled values to the computer.)

基于51单片机控制的实时时钟显示，芯片选择ds1302,掉电时钟可以继续走。(Based on 51 single chip microcomputer control, according to the real time clock chip ds1302, off the electric clock can continue to go.)
