51 单片机 实现 计算器功能，通过键盘输入并且由数码管显示，由蜂鸣器判别按键音-51 MCU calculator function, through keyboard input and the digital display, touch-tone discrimination by the buzzer

PIC单片机采用SR锁存器功能写的电容触摸按键的代码mTouchDemoCap12F206-mTouchDemoCap12F206

与单片机相连的12864液晶，led灯，按键等的驱动控制程序-12864, led lights, buttons, connected with the microcontroller drive control program

基于MSP430的红外遥控解码实验，通过红外遥控板按键发送给MSP430，单片机按照相应的解码规则解码出对应的键盘数字。-Send via infrared remote control panel makes infrared remote control decoding experiments based on MSP430, MSP430, microcontroller decoding in accordance with the appropriate decoding rules

这是一个能够不触摸就能检测到按键是否按下的芯片的编程源代码，我已经使用过很多次了，很好用，是模块式的可以和任何单片机结合使用。-This is a can not touch can detect whether keys pressed chip programming source code, I have used many times, very good, is the module type can be used in conjunction with any single chi
