急求教一个关于Keil uVision3的问题

只看该作者 · 2008-9-10 12:38

在中Keil uVision3用printf("Hello C51 ")语句，我编译、运行之后打开串口看仿真结果却什么都没显示！请问一下为什么这样？谢谢
#pragma
#include<reg51.h>
#include<stdio.h>
void main()
{
SCON=0X50;
TMOD|=0x20;
TH1=0xf3;
TR1=1;
T1=1;
printf("Hello C51 ");
while(1){}
}

能不能看到效果不是自己试一下就知道了吗？？？？

不过第一眼看上去，s1这个变量的初值不会是0的，局部变量是不会自动初始化的。

我试过了，编译能通过，运行仿真时Keil uVision3的提示窗口显示代码过大，Keil uVision3软件我这几天才学习的，所以我想请高手帮我看一下是不是软件还要设置其他东西啊谢谢

你不会用的是限制版吧找个**板的

我用的就是**版的啊

你的数组太大的缘故吧，把数组减小试试

只看该作者 · 2008-9-10 17:00

我已经把数组减少了但运行仿真后打开串口看还是什么东西都没有，这是为什么呢？
