这是一个关于单片机开发的实例，讲述的是单片机上18B20的使用，通过用C语言进行一定的编程，以实现温度传感器的应用。(This is a single chip microcomputer development as an example, tells the microcontroller on the use of 18 b20, through certain programming in C language, in order to realize the application of temperature sensor. )

基于51单片机的 红外+LCD+继电器C程序显示 实现的功能较多，比较适合初学的人。(Based on 51 single-chip infrared+LCD+ relay C program display of more functions, more suitable for beginners person.)

使用C语言代码51单片机的串口仿真实现,意识到C被用来模拟串口的功能 (Using C language code of the serial port of 51 single-chip microcomputer simulation implementation, realized how C was used to simulate the function of the serial port )

说明：  系统工作电源AC220V 根据室内光线调节遥控灵敏度。 主控室电脑负责接收由控制终端传来的遥控信号播放相应多媒体影音文件； 通过主控电脑也可直接点播各展品文件，同时控制打开对应的展品照明； 遥控终端接收激光棒控制信号，控制开灯照明正在解说的展品，并通过通信总线通知主机播放相应文件； 通信中继器负责全部终端与主机间的双向信号传递； 扩展功能：设计上位机播放操作软件，控制照明灯亮度。 (无)

通过PWM定时器延迟一秒，实现一个LED灯的明灭。实验中观察I/O口的值对LED灯的明灭的控制，学习I/O口的输入输出方式和设置，了解PWM的配置方式(Through the PWM timer to delay a second, the realization of a LED lamp at. I/O values for LED lamp light control experiment, learning I/O port input and output method and setting, understanding of PWM configuration methods)

基于低功耗单片机msp430f5438a的spiflash w25q128驱动 读写擦除(Based on low-power microcontroller msp430f5438a of spiflash w25q128 drive to read and write erase)

说明：  18B20数字温度计，驱动液晶显示的，可以实现报警功能(18B20 digital thermometer, to drive liquid crystal display, alarm function can be achieved)

STM32F1与FPGA通过SPI进行通信，我上传的是32部分的程序，已经通过串口测试成功。此程序可拓展为和单片机，DSP通过SPI进行通信(STM32F1 and FPGA communication through the SPI, I uploaded the 32 part of the procedure has been successfully tested through the serial port. This program can be extended to and single-chip, DSP communication through the SPI)

由于太阳能充电系统多在户外，为了方便研究太阳能充电控制系统对蓄电池的充电情况，本文使用GPRS无线传输技术，设计了一套太阳能充电系统蓄电池的充电电压电流远程实时监测系统。系统的硬件部分由电压电流检测电路、单片机STC89C52RC、GPRS模块SIM300以及相应的外围电路构成，下位机软件由C语言编写并与硬件部分构成系统下位机部份，实现了对充电电压电流的信息采集以及数据的无线数传。上位机在LabVIEW2010环境下编写，具备友好的人机交互界面，实现了数据的远程接收、实时显示、数据库管理、报表生成和打印等功能。经过系统测试系统实现了对电压电流的远程监测。(As the solar charging system more outdoors, in order to facilitate the study of solar charge control system for charging the battery case, we use GPRS wireless transmission technology, we designed a solar charging system battery charge voltage and current remote monitoring system. The hardware part of the system by the voltage and current detecting circuit, microcontroller STC89C52RC, GPRS module SIM300 and corresponding peripheral circuits, lower computer software written in C language and hardware parts lower position machine part of the system, the realization of the charging voltage and current information collection and wireless data transmission of data. PC at LabVIEW2010 prepared environment, with friendly interactive interface, realize the remote receiving data, real-time display, management, report generation and printing. After the system test system enables remote monitoring of voltage and current.)

该程序主要用来测量信号的脉冲宽度，具有较好的稳定性和精度。(The program is mainly used for the measurement of pulse width signal,and has good stability and accuracy. )
