#1：同样的代码，仿真显示正常
#2：只要首地址写入数字，就显示不对；比如首地址写入1，那么硬件上显示的为q;若首地址写入0，那么硬件上显示的为p;
#3：请大哥们帮忙分析一下，抱拳谢过！
- --发送数据

- ------------------初始化---------------------------
- void LCD_Init()
- { //LCD_Write_command(0x33);
-
- //LCD_Write_command(0x32);//复位后LCD默认是8线的；需将最后四位改成0010;也就是说低字节只要是0010就能改为4线
-
- LCD_Write_command(0x02);//同上；只要最后4位是0010即可；这一行和上一行任选其一即可；
- LCD_Write_command(0x28);//在四位线下的初始化
- LCD_Write_command(0x0C);//开显示,不显示光标
- LCD_Write_command(0x06); //写一个指针加1
- LCD_Write_command(0x01); //清屏
- Lcd1602_Delay1ms(5);
- LCD_Write_command(0x80); //设置数据指针起点
-

就是麻烦了点
