单片机C语言程序设计实训 100 例—基于 8051+Proteus仿真案例程序

《单片机C语言程序设计实训 100 例—基于 8051+Proteus

仿真》案例

第 01 篇 基础程序设计

01 闪烁的 LED

#include

#define uchar unsigned char

#define uint unsigned int sbit LED=P1^0; //延时

void DelayMS(uint x) {

uchar i; while(x--) {

for(i=0;i<120;i++); } }

//主程序 void main() {

while(1) {

LED=~LED; DelayMS(150); } }

02 从左到右的流水灯

#include #include

#define uchar unsigned char #define uint unsigned int

//延时

void DelayMS(uint x) {

uchar i; while(x--) {

for(i=0;i<120;i++); } }

//主程序 void main() {

P0=0xfe; while(1) {

P0=_crol_(P0,1); //P0 的值向左循环移动 DelayMS(150); } }

03 8 只 LED 左右来回点亮

#include #include

#define uchar unsigned char #define uint unsigned int //延时

void DelayMS(uint x) {

uchar i; while(x--) {

for(i=0;i<120;i++);

} }

//主程序 void main() {

uchar i; P2=0x01; while(1) {

for(i=0;i<7;i++) {

P2=_crol_(P2,1); //P2 的值向左循环移动 DelayMS(150); }

for(i=0;i<7;i++) {

P2=_cror_(P2,1); //P2 的值向右循环移动 DelayMS(150); } } }

04 花样流水灯

#include

#define uchar unsigned char

#define uint unsigned int uchar code Pattern_P0[]= {
