PCF8563时钟模块显示时间在oled上显示有问题

ID:906945 · 发表于 2021-7-21 09:03

我写了这个代码，但是不知道为什么日期无法正常显示，其他全是正常的代码如下
#define MAIN_Fosc 11059200L  //定义主时钟
#include "STC8.H"
#include "OLED.h"
#include "PCF8563.h"

void main()
{
  P2M1 |= 0x30;       P2M0 |= 0x30; //设置P2.4和P2.5为开漏输出
      OLED_Init();       //对OLED屏初始化
  OLED_Fill(0x00);    //清屏
  delay_ms(1000);
  LCD_P8x16Str(0,0," 2000-00-00 0 ");
      LCD_P8x16Str(0,2," 12:00:00 ");
      delay_ms(10);//等待初始化完成

      I2C_init();          //IIC初始化
      EA = 1;                         //打开总中断
  WriteRTC();
      delay_ms(20);
  while(1)
      { ReadRTC();                               //读PCF8563时钟值，即读出时、分、秒

                     OLED_ShowChar(6*8,0,year%10+'0');

                     OLED_ShowChar(8*8,2,minute%10+'0');

                     OLED_ShowChar(11*8,2,second%10+'0');

                     delay_ms(50); //刷新

年月等写入和读出都正常，问题只能是出在日地址错误或者数据被篡改了，8563我还没用过，看了一下程序，地址是自增量的，处于中间的日不应该会出错，查看程序涉及日处理的地方，都没见出错的地方，最后回归到地址上，年月日星期时分秒，按惯性思维看似没错，打开 8563的手册，才发现经验害死人，你自己估计都没认真看手册吧？
