pic单片机
DB4~DB7:在L CD中的作用,为数据线,DB0~DB2接地,DB3接高电平以完成对液晶的初始化。本Demo例子程序中,与单片机的RB2~RB5连接,用户使用其他的管腿时,只需修改#define部分。
RS为数据、指令控制线,与单片机的RB1连接,当RS为高电平时对LCD模块数据寄存器操作,当RS为低电平时对LCD模块指令寄存器操作;
E为读写使能控制线,与单片机的RA5连接,每当E线向LCD模块发送一个正脉冲,LCD模块与单片机之间将进行一次数据交换;
A、K分别是LCD模块背光的正负电源引脚,1-1所示,我们将用RC2控制背光,改变R29的值将改变背光亮度
R/W为读写选择线,在ICD2DEMO教学实验板中,R/W线接地,只做对LCD模块的写操作

用单片机控制红外编码探测障碍物。本文提出解决干扰的方案是:由单片机控制发射有一定意义的红外编码脉冲串,同时,单片机接收该脉冲串。如果接收到的信号和发射的信号基本一致,才判断为有障碍物的存在。-MCU control infrared obstacle detection coding. In this paper, to resolve the interference of the program are: the launch by the single-chip control has a certain sense the infrared encoder pulse train at the same time, single-chip microcomputer to receive the pulse train. If the received signal and the signals are basically the same as the launch only to have to judge the existence of obstacles.
