CPU正在执行一项任务A，然后突然停止任务A去执行任务B，执行完任务B再回来继续执行任务A的过程。(CPU is performing A task. A, then suddenly stop tasks to perform A task B, perform the task B come back again continue to perform the task A process.)

zlg 关于rc522 rc523 pn512的底层代码和14443A 和14443B 只要掌握了这些代码就可以开发对应的M1卡和CPU卡读写程序(ZLG about rc522 rc523 pn512 underlying code and 14443 a and 14443 b as long as to master the code can develop corresponding M1 card and CPU card read and write procedures)

基于51单片机的FM1702的一段程序（部分测试通过）(A program based on 51 microcontroller FM1702 (test))

说明：  用TIM1输出6路互补的SPWM，实现电机转动，用VF调频调压(Six complementary SPWM outputs from TIM1 are used to realize motor rotation and VF frequency and voltage regulation.)

说明：  TLC5615产生各种波形，dac处理芯片，精度为十位的DAC，产生方波 正弦波 三角波等(TLC5615Produce various waveform形)

基于单片机的智能家居系统：红外遥控，红外报警 ，光与LED灯，串口显示光信息 ，时间显示，电机正转，，电机反转，温度报警 (Microcontroller-based Smart Home System: Infrared remote control, infrared alarm, light and LED lights, serial optical information display, time display, the motor is transferred, motor reversal, temperature alarm)

键盘控制舵机同时会让led闪烁，适合慧净HL-1的初学者，但是没有注释(Keyboard control steering gear at the same time will make the led flashing, is suitable for the beginners, hui net- HL 1 but there is no comment)

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)
