cPP

这是一个气体传感器的元件封装库，型号为mq-135，使用dxp开发。(This is a gas sensor element package repository, model mq-135, using dxp development.)

说明：  这是一个使用了8位移位寄存器HC595的电子钟程序，里面包括了仿真程序。以及HC595的操作说明。(This is a used 8-bit shift register of the electronic bell HC595 procedures, which include the simulation program. As well as instructions HC595.)

可以产生幅度、频率可调的方波，频率50hz到1M(Can produce the amplitude, frequency adjustable Fang Bo, frequency of 50Hz to 1M)

基于PSCAD/EMTDC的感应电动机负荷模型对电压恢复的影响。(Influence PSCAD/EMTDC induction motor load model based on voltage recovery.)

GUI用户界面用来显示电路波形，即示波器，STM32编程实现(STM32 and GUI for application to show electronic waves accounting for testing the circuits.)

This second edition cancels and replaces the first edition, ISO/IEC 9899:1990, as amended and corrected by ISO/IEC 9899/COR1:1994, ISO/IEC 9899/AMD1:1995, and ISO/IEC 9899/COR2:1996.

模拟PWM信号控制小灯，控制二极管占空比(Analog PWM signal control light)

对RC500卡的读和写，假如刷卡正确的话模块上的LED灯就会亮，没有卡、卡不对、或是其他的不能识别的都不能通过(RC500 card to read and write, if correct module on the card will be light, LED lamp without card and card wrong, or other cannot identify cannot pass)

使用读卡器实现了为个人化的IC卡数据读写(Achieved using the reader for personal IC card data read and write)

改程序适应于电力系统短路电流计算，生成节点导纳矩阵和阻抗矩阵。(Change program suitable for power system short-circuit current calculation, to generate the node admittance matrix and the impedance matrix.)
