基于sVPWM的三相并网逆变器仿真模型，可用于光伏逆变器-(Simulation model of three-phase inverter)

两份基于51单片机的交通灯，包括原理图，proteus仿真，PCB，实训报告等。是我单片机实训时的成品，调试成功的。(Based on 51 single two traffic lights, including schematics, proteus simulation, PCB, training reports. SCM training when I was finished, debugging success.)

说明：  本系统采用下位机负责模拟数据的采集,从51单片机负责采集数据，并应答主机发送的命令，上位机即主机是负责处理接受过来的数字量的处理及显示，主机和从机之间用RS-485进行通信。这样用户可以在上位机上编写各种程序对文件中的数据进行有效查询和分析,有利于工业过程的长期正常运行和检查。该系统采用的是STC89C52单片机，此芯片功能比较强大，能够满足设计要求。(In this system, the lower computer is responsible for the acquisition of analog data, and the 51 single chip microcomputer is responsible for collecting data and answering the commands sent by the host computer. The host computer is responsible for processing and displaying the received digital quantity. The communication between the host computer and the slave computer uses RS-485. In this way, users can write various programs on the upper computer to effectively query and analyze the data in the file, which is conducive to the long-term normal operation and inspection of industrial processes. The system uses STC89C52 single chip microcomputer, which is powerful and can meet the design requirements.)

近段时间闲来无事做了一款AV和HI-FI两用的前级，采用音量音调处理芯片PT2322完成音量音调的处理，支持六声道音量0~15分贝可调，高中低音支持-7db~+7db可调，总音量支持0~79分贝可调，步进为2分贝每次，并且具有静音、3D和直通功能，不论是在听音乐还是在看电影两不误；采用pt2323实现音源输入选择和2声道转换成6声道的功能，支持四组普通立体声输入和一组DVD六声道输入，并且能够将四组立体声其中的任何一组转换成六声道，即使是用VCD看普通碟片时也能欣赏到有如DVD一样的环绕音效。由于PT2323和PT2322支持I2C总线控制，利用89c51对其进行控制，PCB板连线方便，控制简单。本板除了以上功能外，还特留有一个输出口，用来控制后面所接的功率放大模块的电源的关断，以实现遥控开关机，静音时也将功率放大模块的电源模块关断，以实现节能的目的。本电路还有一个重要特点，整个电路采用单5V电源供电，接口简单，连线方便，便入摩机用。人对电路操作主要有两种方式，一是通过键盘来进行控制，二是通过配有的红处的遥控接收头来控制，遥控器可选市面上很容易买到的由TC9148型的遥控器即可。本人提供少量PCB板，供爱好音响和单片机的同行做实验， 如有需要也可提供全套散件或成品板。 (err)

oled屏幕上面显示时分秒，可自行控制暂停(Time and seconds are displayed on the OLED screen, and the pause can be controlled by itself.)

说明：  msp430g2553使用1306显示超声波测距(2553 Displays Ultrasound Ranging by 1306)

窃听器的简单电路，呵呵，供研究使用，请勿用于其他非法用途。(wiretapped simple circuit Oh, for research use, please do not used for other illegal purposes.)

说明：  最简单的读取AD值的程序。初始化时调用初始化程序，运行过程中，可以定时读取AD值。可以用做温度检测或者电压检测。(The simplest program to read AD values. Initialization call initialization program, running process, can read AD value at regular intervals. It can be used for temperature detection or voltage detection.)
