51单片机烧不进去程序，我肯定不是硬件问题，求解答啊
我做了一个AT89S52 和16*16点阵滚动显示电路，可以正常下载到单片机，
但是我后来加了一个中断用LED点阵显示温度。。。程序在PROTEUS仿真没问题，一切正常，但是无论怎么样就是下载不到单片机里面，其他的程序都可以。。到底怎么回事
附上源程序

烧不进去从有提示吧？
超出容量了吧？
容量没超，楼主程序第117行定义的数组没有用};结束。
不知道，看看学习，有什么提示？
用示波器量量RX有没有接收到信号，看看晶振有没有跑起来，握手成功吗，握手没成功 就可能还是硬件的问题了
熔丝设置对吗？

这个是我在上传的时候忘打了。。在KEIL中编译通过了，显示data=107 xdata=0&&.HEX文件也生成了，但是就是烧不进去单片机。。其他的程序一切正常，唯独这个不行……

这个没有问题的，因为其他程序都可以正常烧进去

我可以肯定USBASP下载没问题，因为其他程序可以写进去。。。唯独这个不行……我想应该是软件的问题，是不是中断出问题了，可就是找不到原因

没什么反应。。点烧录，然后软件界面显示烧录成功，硬件没反应。。。其他的程序正常
是下载程序的软件没设置好吧，你关闭重新找开试试。我以前也下不进去，但关了就好了，下着着又会下不进去，擦除一下芯片也有时会好。

求：单片机用按键控制一个闪烁灯开和关的C语言程序
求：单片机用按键控制一个闪烁灯开和关的C语言程序
比如在以下的程序里加一个开关按键，按下按键灯闪烁，松开按键按灯灭（以下是的程序）
#include ®52.h&
sbit LED=P2^0;
//延时函数，含有输入参数unsigned int x，无返回值unsigned int是宏定义无符号整型变量，其值的范围是0~65535
void delay(unsigned int x)
& &&&while(x--);
void main(void)
& & while(1)//无限循环
& && && &&&LED=0;//P2.0输出低电平，点亮LED灯
& && && &&&delay(2000);//调用延时函数，更改X值，相当于更改LED灯闪烁的频率
& && && &&&LED=1;//P2.0输出高电平，熄灭LED灯
& && && &&&delay(2000);//调用延时函数，更改X值，相当于更改LED灯闪烁的频率
给你个程序，相互学习下
给个程序，相互学习。
#include ®52.H&
#define uchar unsigned char
#define uint unsigned int
sbit led=P2^0;
sbit key=P1^0;
void delay(uint x)
& & & & uint i,j;
& & & & for(i=x;i&0;i--)
& & & & & & & & for(j=110;j&0;j--);
void keys()
& & & & if(key==0){led=~delay(500);}
& & & & else{led=1;}
void main()
& & & & while(1)
& & & & & & & & keys();
void keys()
if(key==0){led=~delay(500);}
else{led=1;}
写的很好！ 给我感触
