一個是LCD顯示溫濕度的程序如下
#include <reg51.h>
#include <intrins.h>
typedef unsigned char BYTE;
typedef unsigned int WORD;
#define uint unsigned int
#define uchar unsigned char
sbit io=P2^2;

void delay(uchar ms)
{

while(ms--)
for(i=0;i<100;i++);
}
void delay1()
{

for(i=0;i<1;i++);
}
BOOL lcd_bz()
{

rs=0;
rw=1;
ep=1;
_nop_();
_nop_();
_nop_();
_nop_();
result = (BOOL)(P2&0x80);
ep=0;
return result ;
}
void write_cmd(uchar cmd)
{
while (lcd_bz());
rs=0;
rw=0;
ep=0;
_nop_();
_nop_();

_nop_();

}
void write_addr(uchar addr)
{

}
void write_byte(uchar dat)
{

{

}
void display(uchar addr,uchar q)
{

}
void start()
{

}

}
void receive()
{

{

}
}
}
void main()
{

while(1)
{

display(0x00,'R');
display(0x01,':');
display(0x02,RH/10+0x30);

display(0x43,TH%10+0x30);
display(0x44,0xdf);
display(0x45,0x43);
}
}
另一個是PWN調光的程序如下
/*單片機實現PWM調節LED燈的亮度*/
#include<reg52.h>
#define uchar unsigned char
sbit P2_0=P2^0;
sbit P2_1=P2^1;
sbit key1=P1^0;
sbit key2=P1^1;
sbit key3=P1^2;
sbit key4=P1^3;
uchar zkb,i;// zkb指占空比
uchar zkb2,i;
void time0(void) interrupt 1 //中斷函數
{
TH0=(65536-10)/256;
TL0=(65536-10)%256;
++i;
if(i>10)
{
i=0;
};
if(i<=zkb)
{
P2_0=1;
}
else P2_0=0;
if(i<=zkb2)
{
P2_1=1;
}
else P2_1=0;
}
void delay(uchar z)
{
uchar x,y;
for(x=z;x>0;x--)
for(y=110;y>0;y--);
}
void init() //初始化函數
{
TMOD=0X01;
TH0=(65536-10)/256;
TL0=(65536-10)%256;
EA=1;
ET0=1;
TR0=1;
}
void keyscan() //鍵盤掃描
{
P1=0XFF;
if(key1==0)
{
delay(5);
if(key1==0)
{
while(!key1);
if(zkb<9)
{
zkb++;
}
}
}
if(key2==0)
{
delay(5);
if(key2==0)
{
while(!key2);
if(zkb>0)
{
zkb--;
}
}
}
if(key3==0)
{
delay(5);
if(key3==0)
{
while(!key3);
if(zkb2<9)
{
zkb2++;
}
}
}
if(key4==0)
{
delay(5);
if(key4==0)
{
while(!key4);
if(zkb2>0)
{
zkb2--;
}
}
}
}
void main() //主函數
{
zkb=2;
zkb2=2;
init();
while(1)
{
keyscan();
}
}
有沒有大俠幫忙看下怎么合并在一起 兩個程序單獨都可以下載到板子里實現功能 想同時實現功能自己不會合并 本人學生新手小白一個 程序是網上找的 有沒有大佬幫忙合并一下 想跟著學學
