一个51单片机实现软件计数器的源程序代码-a 51 SCM software counter of the source code

3*4键盘扫描程序 已加消抖功能 可以扩展为4*4~~~ 只用8个I/O口就能实现-3* 4 keypad scanner Buffeting extinction have been added functions can be extended to 4* 4 ~ ~ ~ only eight I/O port will be able to realize

51单片机的源程序集，有存储器，点阵式液晶，进制转换，led,ad等。-51 SCM source collection, storage, dot-matrix LCD, the base for the conversion, led, ad so.

实现IEEE802。15。4协议的开发板的USB驱动，完成了高速数据传输-Realize IEEE802. 15. 4 protocol development board

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

用单片机的C语言编的键盘递增递减的C程序的源代码（按一下键，对应的键值增或减一），在很多领域用到此思想，如空调调温等，可供单片机开发工程师参考。-the MCU series of the C language keyboard incremental decrease in C program"s source code (by pushing a button, the corresponding increase or decrease of the pair a), used in many areas here thinking, such as air-conditioning thermostat, MCU development engineers for reference.

51单片机测量电机转速，利用计数脉冲数显示到汉字液晶屏上面。脉冲是由对管扫描码盘产生的-51 MCU measuring motor speed using pulse-counting the number of
