㈢ 51單片機圖形液晶顯示主函數流程圖

你把程序格式弄的規范一些，很好看出來的。。。我只畫了一個流程圖給你，另外一個也很簡單的嘛，自己動手弄弄吧。。;延時子程序_1
DELAY1: PUSH 05H
MOV R5,#10H
DELAY2:
LCALL DISP1 ;調用子程序DISP1
DJNZ R5,DELAY2
POP 05H ;延時子程序_2
DELAY12:
PUSH 06H
PUSH 05H
MOV R6,#4
DELAY21:
MOV R5,#225
DELAY31:
DJNZ R5,DELAY31
DJNZ R6,DELAY21
POP 05H
POP 06H
RET
END

㈣ 如何用單片機C語言編寫液晶顯示程序

在中斷程序中，不退出，又出現了本中斷的申請，單片機，是不會再一次進入該中斷程序的。只有高級的中斷，才能中斷本次中斷。當退出本次中斷後，回到主程序執行了一條指令，在處於主程序期間，單片機才會顧及已經出現的申請。但是，如果，該申請標志，已經消失，單片機就不會發生中斷。這個過程，有些書，講的很詳細。有些書，就沒有講。

這個簡單，你在當前菜單下設置一個下翻的按鍵，按一下時，重新寫入後面的顯示內容，也就是將前三行的內容刪除掉，重新寫入。

delate(page1);
write(page2);
}
void delate(unsigned char page)
{
