使用usrp1或usrp n210搭建rfid，环境，gnuradio 3.4.2 ubuntu 10.10(usrp1,usrp2,make rfid gnuradio 3.4.2 ubuntu 10.10)

这是一个51单片机小程序，功能是实现跑马表，只有三位。(This is a small program the microcontroller 51, the table function is to achieve the Happy Valley, only three.)

1000以内所有的完数，比较简单，用于学习和交流(1000 all finished within few, relatively simple, for learning and communication)

at89c2051利用74ls164 驱动 共阳极数码管(74ls164 driver to use a total of at89c2051 digital tube anode)

这是一个能生成C程序代码的软件，用来编写液晶屏上的内容非常方便。(This is a program that generates C source software, used to write the contents on the LCD screen is very convenient.)

直流斩波变化的仿真和一些参考文献 可以学习一下(The simulation of dc chopper change and some references can learn )

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.)

该项目首先是利用单片机对鱼缸的温度进行智能控制。首先通过外部按键对鱼缸所需温度进行设定。温度传感器 DS18B20 采集温度信息在外围的 LCD 上显示出来。其次是利用光电耦合器判断有无鱼饵，若无鱼饵，发出提示，若有鱼饵，则执行自动投食或手动投食功能。(The project first is the use of single-chip microcomputer to control the temperature of the fish tank. First, the temperature of the fish tank is set by the external button. The temperature sensor DS18B20 collects the temperature information to display on the periphery LCD. Followed by using photoelectric coupler to determine whether the bait, if there is no bait, alert, if there is a bait, automatic throw in and throw food or manually cast and functional food.)
