stm32f103战舰v3OLED显示时间源程序

（适用正点原子的开发板）主要是在OLED 屏幕上实时时间，如果时间不准时，可以先使用实验15 RTC实验然后烧写进开发板，在XCOM串口调试助手发送命令如：RTC_Set(2020,06,04,23,25,30) 即可完成RTC校准！！！！

main.c代码如下：

#include "led.h"
#include "delay.h"
#include "key.h"
#include "sys.h"
#include "oled.h"
#include "rtc.h"

int main(void)
{       u8 t=0;
      delay_init();                   //延时函数初始化
      RTC_Init();                               //RTC初始化
      NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);       //设置NVIC中断分组2:2位抢占优先级，2位响应优先级
      LED_Init();                            //LED端口初始化
      OLED_Init();                      //初始化OLED
  OLED_ShowString(0,0,"ALIENTEK",24);

      OLED_Refresh_Gram();             //更新显示到OLED

      while(1)
      {
               OLED_Refresh_Gram();
            delay_ms(500);
            LED0=!LED0;
            if(t!=calendar.sec)
            {
                     t=calendar.sec;
                     OLED_ShowNum(0,24,calendar.w_year,4,12);
                        OLED_ShowString(24,24, "-",12);
                     if(calendar.w_month<10)
                     {
