㈢ 51单片机图形液晶显示主函数流程图

你把程序格式弄的规范一些，很好看出来的。。。我只画了一个流程图给你，另外一个也很简单的嘛，自己动手弄弄吧。。;延时子程序_1
DELAY1: PUSH 05H
MOV R5,#10H
DELAY2:
LCALL DISP1 ;调用子程序DISP1
DJNZ R5,DELAY2
POP 05H ;延时子程序_2
DELAY12:
PUSH 06H
PUSH 05H
MOV R6,#4
DELAY21:

DELAY31:

㈣ 如何用单片机C语言编写液晶显示程序

在中断程序中，不退出，又出现了本中断的申请，单片机，是不会再一次进入该中断程序的。只有高级的中断，才能中断本次中断。当退出本次中断后，回到主程序执行了一条指令，在处于主程序期间，单片机才会顾及已经出现的申请。但是，如果，该申请标志，已经消失，单片机就不会发生中断。这个过程，有些书，讲的很详细。有些书，就没有讲。

㈦ 单片机液晶翻页显示的程序

这个简单，你在当前菜单下设置一个下翻的按键，按一下时，重新写入后面的显示内容，也就是将前三行的内容删除掉，重新写入。
if(KEY_NEXT)
{
delate(page1);
write(page2);
}
void delate(unsigned char page)
{
...............
}
void write(unsigned char page)
{
...............
}
