可以定義一個(gè)變量記錄按下的次數(shù)來控制流動(dòng)方式

我這里有一個(gè)與你說的類似的程序，它是用外部中斷來切換點(diǎn)陣顯示的程序，你自己看看，學(xué)習(xí)學(xué)習(xí)，再變成你自己的程序吧。
#include <reg52.h>

#define uchar unsigned char
#define uint unsigned int     //宏定義

sbit KEY=P3^4;      //定義畫面切換按鍵，可以不定義，外部中斷會(huì)自己認(rèn)的

uchar KY;
uchar disp;
uchar pic=0,num=0;      //pic為按鍵次數(shù)；num為中斷次數(shù)
