程序原本是51程序，移到STM32的时候有个地方报错：

};
调用它的程序是：
void showpic(char *k)
{
        int i,j;
        for(i=0;i<8;i++)
        {
            
            for(j=0;j<128;j++)
        {
            write_data(*k++);
        }
        }
}

调用时：
showpic（bmp）;
在keil 51时编译没问题。

};

调用的子程序：
void showpic1(unsigned char *k)
{
        int i,j;
        for(i=0;i<8;i++)
        {
            
            for(j=0;j<128;j++)
                {
                        write_data(*k++);
                }
        }  
}

按以下写法调用时报错。
提示：../Src/main.c(175): error:  #167: argument of type "const unsigned char *" is incompatible with parameter of type "unsigned char *"
===============================================

showpic(bmp);
===================
把const去掉，编译就OK，可是我又想把这个数组放在FLASH里，该怎么写才正确？？
