运行看下仿真的效果
emmmmmm……少个琪，我们来看下原因
如下代码导致我们显示错误，下面仔细剖析代码组成
void display(void)
{
select(1);
display_zf(0,40,3,0);
display_hz(2,0,4,0);
display_hz(4,32,2,8);
select(2);
display_zf(0,0,4,3);
display_hz(2,0,4,4);
display_hz(4,0,2,10);
}
想要看某一段程序具体的作用，最快捷的方法便是将其注释，查看仿真器的显示结果，便可确定其作用。
我们注释掉两行代码
//在LCD上显示
void display(void)
{
select(1);
display_zf(0,40,3,0);
display_hz(2,0,4,0);
//display_hz(4,32,2,8);
select(2);
display_zf(0,0,4,3);
display_hz(2,0,4,4);
//display_hz(4,0,2,10);
}
查看显示结果
显然最下面一行文字消失了，所以这两行就是显示最下面文字的作用。
为更加确定其作用，以及方便修改，下面我们详细看一下display_hz(2,0,4,0);这个子函数.
void display_hz(uchar c_page,uchar c_column,uchar num,uchar offset)
{
uchar c1,c2,c3;
for(c1=0;c1<num;c1++)
{
for(c2=0;c2<2;c2++)
{
for(c3=0;c3<16;c3++)
{
send_cmd(lcdpage+c_page+c2);
send_cmd(lcdcolumn+c_column+c1*16+c3);
send_data(table_hz[(c1+offset)*32+c2*16+c3]);
}
}
}
}
//c_page为当前页,c_column为当前列，num为字符数，
//offset为所取汉字在显示缓冲区中的偏移单位
我们得以知道，实参c_page为当前页，形参4我们就能明白表示的是第四页。
如下图所示，分别为0，2，4行。
同理，num表示需要出现的字符数、select(1);便是左半个屏幕显示、select(2);便是右半个屏幕显示。
于是，我们得以明白，之所以琪不显示，因为我们设置的num参数为2，但是我们的文字比原程序多了一位，所以参数应为3.
修改如下：
void display(void)
{
select(1);
display_zf(0,40,3,0);
display_hz(2,0,4,0);
display_hz(4,32,2,8);
select(2);
display_zf(0,0,4,3);
display_hz(2,0,4,4);
display_hz(4,0,3,10);//~！！！！！！2改为3
}
结果：
修改学号

};
仿真结果为：
少两个数，嗯？？？仿照文字修改方式，将num中的4改为6（因为用4学号少两位，所以4+2=6）
将文字适应程序：在这里插入代码片
void display(void)
{
select(1);
display_zf(0,40,3,0);//学号
display_hz(2,0,4,0);//汉字
display_hz(4,32,2,8);
select(2);
display_zf(0,0,4,3);
display_hz(2,0,4,4);
display_hz(4,0,3,10);
}
修改为：
void display(void)
{
select(1);
display_zf(0,40,3,0);
display_hz(2,0,4,0);
display_hz(4,32,2,8);
select(2);
display_zf(0,0,6,3);
display_hz(2,0,4,4);
display_hz(4,0,3,10);
}
成了，不过有一个问题，学号没有居中，我们可以修改一下：
void display(void)
{
select(1);
display_zf(0,25,5,0);/（第二个参数改成24，24是列数，原来是40，太靠右，往左去一下）
display_hz(2,0,4,0);
display_hz(4,32,2,8);
select(2);
display_zf(0,1,4,5);/学号一共9位，select（1）显示5位，所以select（2）显示三位；注意此时display_zf函数第四个参数必须和上一个display_zf倒数第二位一样，也就是说：5=5.
display_hz(2,0,4,4);
display_hz(4,0,3,10);
}
