读写器与射频卡通信的设计采用RC522射频读写芯片与射频卡进行通信，符合ISO14443规范协议；硬件系统设计中主要有AVR单片机主控模块、电源模块、存储模块、外部时钟模块、LCD模块；软件系统设计采用C语言，遵循模块化和结构化编程模式，设计了射频卡操作程序、软关机与自动关机程序、LCD显示、串行Flash存储器、外部时钟等外部设备驱动程序。所设计的手持式读写器具备对MF1 S50、S70射频卡的读写、实时状态显示、系统在线升级以及关机等功能。(This handset can process the data offline or online, reading and writing from 10 cm far. This handset is low-power, miniature, modular design and so on. This article includes: the communication design between RF card and Reader, hardware system design and software systems design. The communication design between RF card and Reader used to RC522 RF chip control RF cards, in line with ISO14443 standard protocol Hardware system design mainly include AVR microcontroller control modules, power modules, memory modules, external clock modules, LCD modules Software system designed with C programming language, and follow the modular structure of the programming model, and has the RF card operation procedures, soft shutdown and automatic shutdown procedures, LCD display, serial Flash memory, an external clock, and other external device driver Procedures. The handset readers has the MF1 S50, S70 RF card reader function, real-time status display function, the system online update function and so)

利用MSP430单片机实现5分钟倒计时。用Timer_A实现1s定时，4位共阳型数码管显示时间，显示格式为：“x-xx”，分别代表“分”、“十秒”和“秒”。每隔1s，倒计时器的时间减1，倒计时从4分59秒开始计时，至0分0秒结束，停止计时。(MSP430 microcontroller is used to realize 5 minute countdown. Timer_A is used to realize 1s timing and 4-bit common-sun digital tube display time. The display format is "x-x x", representing "minutes", "ten seconds" and "seconds" respectively. Every 1s, the countdown time is reduced by 1. The countdown time starts at 4:59 seconds and ends at 0:0 seconds.)

AD7991采集数据程序，C语言编程，keil软件，可实现三通道轮流采集，程序中添加串口显示返回值，亲测，可用(AD7991 data collection procedures, C programming language, keil software, can achieve a three channel samples in turn, add serial program to display the return value, pro test available.)

用简单的51单片机制作八路温度巡检仪表，绝对好用，AD用的ADC0809,传感器用的PT100(Making eight road temperature inspection instruments with a simple 51 single chip microcomputer)

安富莱这个二代示波器无敌牛，建议下下来学习学习！(Anfulei, the second generation oscilloscope, is invincible. It is suggested that we should learn from it.)
