【求助】keilc 编程 串口输出 显示数组元素

[dabaobear]

unsigned char *c[25]={"00","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24"};
//向串口发送一个字符串,长度不限。
void send_string_com(unsigned char *str)
{
while(*str!='\0')
{
send_char_com(*str);
*str=*str++;
}
*str=0;
}
for(j=1;j<25;j++)
{
send_string_com(c[j]); //※
}

※这个语句编译不通过。非法指针转换。

unsigned char *c[10]={"00","01","02","03","04","05","06","07","08","09"};
我把长度改到 10 就能通过编译了。
我需要24个 怎么改？

不是语法问题,是你的段溢出了,你的DATA区超过了128字节

Program Size: data=173.0

改你变量的存放区域,放到CODE或是XDATA里都可以...

另外:

for(j=1;j<25;j++)
C的数组下标从0开始....

[lbing7]

*str=*str++;//还要注意的是,你这句改动了原缓冲区的数据,这个很危险....

[lbing7]

xdata unsigned char *c[25]={"00","01","02","03","04","05","06","07","08","09","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24"};

xdata 外部数据区64K字节 数据放在那里 对整个程序没有什么影响吗？

如果你的数据是不需要修改的，你也可以改成code（const）

[dabaobear]

^_^ 改成code 就好了。要是用xdate 还要加硬件吧。

不会吧！把编译提示信息和你的全部文件贴出来看看！
