我做的設計
手機裝個藍牙助手，實現指定串口內容控制LED開關。

單片機源程序如下:

#include "main.h"
void main(void)
{
EA = 1;
LED1 = 0;
LED2 = 0;
Delay = 0;
ConfigTimer0();
ConfigUART(9600);
LCD_INIT();
// Write_String(0,0,"Hello");
// Write_String(0,1,"1602113");
string(0x83,"Welcome",7);//寫入welcome
string(0xc3,"1602113",7);//寫入Harbin China
while(1);
}
//main
void delay(int ms)
{
int i,j;
for(i=0;i<ms;i++)
for(j=0;j<125;j++);
}
/* 串口配置函數，baud-通信波特率 */
void ConfigUART(unsigned int baud)
{
SCON = 0x50; //配置串口為模式1
TMOD &= 0x0F; //清零T1的控制位
TMOD |= 0x20; //配置T1為模式2
TH1 = 256 - (11059200/12/32)/baud; //計算T1重載值
TL1 = TH1; //初值等于重載值
ET1 = 0; //禁止T1中斷
ES = 1; //使能串口中斷
TR1 = 1; //啟動T1
}
/* 配置并啟動T0，ms-T0定時時間 */
void ConfigTimer0()
{
TMOD &= 0xF0; //清零T0的控制位
TMOD |= 0x01; //配置T0為模式1
TH0 = T0RH; //加載T0重載值
TL0 = T0RL;
ET0 = 1; //使能T0中斷
TR0 = 1; //啟動T0
}
//1602
void LCD_INIT(void)
{
LCD_RW=0;
write_com(0x38); //顯示模式設置：16×2顯示，5×7點陣，8位數據接口
delay(20);
write_com(0x0f); //顯示模式設置
delay(20);
write_com(0x06); //顯示模式設置：光標右移，字符不移
delay(20);
write_com(0x01); //清屏幕指令，將以前的顯示內容清除
delay(20);
}
void write_com(uchar com)
{
P0=com;
LCD_RS=0;
LCD_EN=0;
delay(10);
LCD_EN=1;
delay(10);
LCD_EN=0;
}
void write_date(uchar date)
{
P0=date;
LCD_RS=1;
LCD_EN=0;
delay(10);
LCD_EN=1;
delay(10);
LCD_EN=0;
}
void string(uchar ad,uchar *p,uchar n)//顯示字符函數
{
uchar i;
write_com(ad);
for(i=0;i<n;i++)
{
write_date(*p++);
delay(50);
}
}
void UART_INT(void) interrupt 4
{
EA = 0;
while(RI)
{
RxdByte = SBUF;
SBUF = SBUF;
switch(RxdByte)
{
case 0x31:LED1 = 1;//LED1開
//Write_String(0,0,"LED1 ON ");
write_com(0x01);
string(0x80,"Controling",10);
string(0xc0,"LED1 ON ",9);
break;
case 0x32:LED1 = 0;//LED1關
//Write_String(0,0,"LED1 OFF ");
write_com(0x01);
string(0x80,"Controling",10);

//Write_String(0,0,"LED2 ON ");
write_com(0x01);

break;

//Write_String(0,0,"LED2 OFF ");
write_com(0x01);

break;
