关于12864清屏后显示闪烁严重的问题
我最近使用UNO做一个倒计时的计分器，使用12864显示。可是我发现如果我不使用清屏程序，本来要显示数字9的时候就会变成90（所有个位数都是这样）。如果使用了清屏程序之后，问题得到解决，可是屏幕闪烁得非常严重。请各位大神指教#include "LCD12864RSPI.h"
#include "MsTimer2.h"
#define AR_SIZE( a ) sizeof( a ) / sizeof( a )
int scorebutton1=7;
int gamestart=0;
int score=0;
int score1=0;
int fangui=0;
int fangui1=0;
int minute=12;//初始分钟
int second=59;//初始秒数
unsigned long time;
unsigned long starttime;
int timeMinute; //显示分钟数
int timeSecond; //显示秒数
unsigned char show0[]={0xC8,0xC8,0xBB,0xF0};//REHUO
unsigned char show1[]={0xC2,0xED,0xB4,0xCC};//MACI
unsigned char show2[]={0xB6,0xD3,0xBC,0xCA,0xB7,0xB8,0xB9,0xE6};//DUIJIFANGUI
///LCD12864RSPI(int _latchPin,int _dataPin,int _clockPin):
//RS->A0,R/W->A1,E->A2
LCD12864RSPI LCDA(A0,A1,A2);
void setup()
{
pinMode(scorebutton1,INPUT);
//pinMode(scorebutton2,INPUT);
MsTimer2::set(1000, flash); // 中断设置函数，每 1000ms 进入一次中断
MsTimer2::start(); //开始计时
}
void loop()
{
if(digitalRead(scorebutton1)==HIGH)
{
//delay(100);
score++;
}
delay(180);
LCDA.setCursor(0,2);
LCDA.print(score);
LCDA.setCursor(0,6);
LCDA.print(score1);
LCDA.setCursor(1,0);
LCDA.print(minute);
LCDA.setCursor(1,2);
LCDA.print(second);
LCDA.setCursor(0,0);
LCDA.chinese(show0,AR_SIZE(show0));
LCDA.setCursor(0,4);
LCDA.chinese(show1,AR_SIZE(show1));
LCDA.setCursor(3,0);
LCDA.chinese(show2,AR_SIZE(show2));
}
void flash() //中断处理函数
{
time=0;
if(time<719)
{
delay(1000);
second--;
if(second==0)
{
minute--;
second=59;
}
time=minute*60+second;
}
} 请考虑一下09 90 9分别占位多少
