51单片机的4x4键盘扫描c语言程序，大家看看，(51 single-chip 4x4 keypad scan, we look)

电场，考虑电导率，电流密度矢量关系式变化关系(Electric field, considering the electric conductivity, the current density variation of the relation vector)

通讯程序，利用的是rs485协议,调试运行可以通过，本人实验过的(This programme is used for the commucation of pc and avr)

用单片机产生频率，占空比可调的方波，这是C语言的原代码。(Produced with single-chip frequency, variable duty cycle square wave, which is the C language source code.)

说明：  单片机I/O口控制红外发射管，模拟格力空调遥控器的代码。典型应用：上位机发送一个通用的“开机，温度，模式……”命令，单片机自动发射出和遥控器一摸一样的波形，实现智能遥控器的功能。 (MCU I/O port control infrared emission control, analog Gree air conditioner remote control code. Typical applications: host computer to send a generic &quot boot, temperature, mode ... ...&quot command, microcontroller and the remote control automatically emit the same wave first touch, intelligent remote control functions.)

基于一款EV1527的解码程序,配合330K震荡电阻使用(Based on the a EV1527 decoding program, with the use of 330K shock resistance)
