51单片机16*16LED点阵滚动显示-电子工程世界

分享到: 微博; QQ; 微信; LinkedIn

功能：LED16*16点阵滚动显示

说明：74LS154用作发送数据，P0,P2口用来列选

看本程序最好的工具最好旁边有标号和语法着色，推荐keil或UltraEdit

懒人提示：要改成自己所要的显示内容，要怎么改？

1.要改显示内容改第23~92行代码，还有第119行代码，具体改法见下面注释

2.要改滚动速度改第102行代码

/*头文件*/

#include

/*宏定义*/

#define uchar unsigned char

#define uint unsigned int

/*函数声明*/

void delay();

/*全局变量*/

uint lie; //列选标志

/**

字模:反显，纵向取模，开头和结尾均加入32个0xFF，用于改善屏滚动显示时循环的连贯性 **/

/**

基于51单片机的L298N直流电机调速系统

本此设计选择STC89C52单片机作为主控芯片，选取带有光电编码器的直流电机作为被控对象，利用单片机的T0定时器产生PWM信号并送到直流电机。在Proteus仿真环境下搭建了L298N直流电机驱动电路、矩阵键盘扫描电路以及LCD12864显示电路。实现了直流电机的启动、加速、正转、反转、制动等功能。同时，采用PID控制算法可实现电机速度在特定的场合实现自动切换。单片机源程序如下: #include reg51.h #include intrins.h #include math.h #include lcd.h #include Key.h #include Motor.h #include LCD12

MCS-51单片机的存储器结构---单片机基础

ROM和RAM容量和位置 MCS-51单片机的存储器包括程序存储器（ROM）和数据存储器（RAM）两部分，而每一部分的容量又包括片内容量和片外容量。一般8x51系列的单片机的ROM内部容量是4KB，外部扩展容量最大的是64KB；RAM内部容量是128B，外部扩展容量最大是64KB。MCS-51单片机进行了扩容，其内部存储器的容量大小是256B。程序存储器（ROM）的调用 EA引脚接高电平时，CPU将使用内部程序存储器，若程序超过4KB，将使用外部存储器存储超过的部分； EA引脚接低电平时，CPU将使用外部程序存储器，而内部程序存储器将形同虚设。数据存储器（RAM）的调用在汇编语言中，访问内部数据存储器

如何使用keil 5 编写 51单片机工程

目前我们通常编写51程序使用的是keil4，而好多编写STM32等单片机程序的使用keil5。那么如何在keil5中兼容51和STM32程序编写，省去切换版本的繁琐呢？很简单只需两步就可以完成。下面这个方法针对已破解keil5的stm32等一系列。这个肯定是最常见的，因为破解keil5然后编写32工程的教程一大把。 1、首先下载编写51的相关东西。可以在官网上下载，例如百度keil官网。点击右上角的DOWNLOADS进入相关的下载界面，下载你需要的安装包。MDK5、c51、c166等，这里只需要下载c51的。当然也可以在下面这个百度网盘链接里下载： 51相关：链接：http://pan.baid
