LCD应用系统程序，里面有proteus仿真程序。

采用AYG-59C GSM MODEM模块，和at89s52的串行口通信。通过at指令控制GSM模块，同时用单片机处理GSM发给单片机串口的反馈信息，实现远程无线控制。-Used AYG-59C GSM MODEM modules, and AT89S52 serial port communications. GSM through at command control module, at the same time deal with single-chip GSM distributed feedback single-chip serial port, wireless remote control.

编译为ICC AVR6.25A ATMEGA16L芯片 MAX7219驱动八位数码管显示-Compiled for the ICC AVR6.25A ATMEGA16L chip MAX7219 LED display driver 8

功能描述： 利用AT89S51单片机的T0、T1的定时计数器功能，来完成对输入的信号进行 频率计数，计数的频率结果通过8位动态数码管显示出来。要求能够对2－40KHZ 的信号频率进行准确计数，计数误差不超过2/1-Functional Description: Using AT89S51 MCU T0, T1 timing counter function, to complete the input signal frequency counting, counting the frequency of 8 resulted in the adoption of dynamic digital tube display. Request to the 2-40KHZ signal frequency accurately count, counting error of less than 2/1

本设计主要是运用单片机设计一个最小系统――电子时钟，它具有24小时计时功能，能够对时间进行调整，并且能实现时、分、秒的显示，同时还有内设闹钟，时间到时候会响铃，响铃时可以通过按键控制延时再启动或关断。与此同时还设置了整点报时功能；并采用采用了软件去抖的方法扫描键盘，动态刷新显示数码管，并通过查表实现译码输出时间等编程方法；-This design is the use of single-chip design of a minimum system- Electronic clock, it has a 24-hour timer function, capable of time to adjust, and can achieve the hours, minutes and seconds display, but also equipped with alarm clocks, time to When ringing the bell to ring when the button control can delay re-start or shutdown. At the same time also set up the whole point timekeeping function and adopt the use of the software to scan the keyboard shaking method, dynamic refresh display digital tube, and through the realization of decoding look-up table output time programming method

7281读写程序//读出BC728X内部寄存器的值 调用参数为寄存器地址-7,281 literacy procedures// BC728X read out the value of the internal register call parameters register address

采集端程序，可以搜所电信号，每次可以采集32个信号，可以用于检测信号好差。-acquisition software, can be found by the electrical signal that can be collected each 32 signal can be used to detect bad signal.

本单片机开发例程含有电路图及C语言，有一定的参考价值-Containing the single-chip circuitry to develop routines and C language, the value of some reference
