MCS
MCS-51单片机有5个中断源,其中两个是由-INT0、-INT1引脚输入的外部中断源;另外三个是内部中断源即由T0、T1的溢出引起中断和串行口发送完一个字节或接收到一个字节数据引起中断。触发外部中断有两种方式,即下降沿引起中断或低电平引起中断。当编程TCON中的ITi(i=0、1)为1时,则引起触发的方式为边沿触发方式,反之(ITi=0)为低电平触发方式。每个中断源的中断请求能否得到响应要受两级“开关”的控制,即一个总“开关”-MCS-51 single-chip has five interrupt sources, two of which are by-INT0,-INT1 pin input external interrupt source the other three internal interrupt sources from the T0, T1 overflow caused by the disruption and serial port sending or receiving end of a byte to a byte of data caused by interruption. Triggered external interrupt has two modes, namely, falling edge or low-level disruption caused disruption caused. When programming TCON in ITi (i = 0,1) for the 1:00 has been the subject of a way to trigger the way to the edge of the trigger, on the contrary (ITi = 0) for low-level trigger mode. Each interrupt source interrupt request can be subject to levels in response to

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

六位电子密码锁
采用89s52(51,52都可),4*4键盘,六个数码管,74ls04(位选),573(8D锁存器)。
说明:P2---数据(接573)―――(接数码管)
P1---位选 ---(按74ls04)
P0--4*4键盘
密码一次性设置(编程时写入的)
电路简单,此源程序仅供初学者学习,可自行扩展密码模块(加24C02)。
