日期的显示代码为：
- Gui_DrawFont_Num32a(160, 300,RED, WHITE, rtc_initpara.year/16);
- Gui_DrawFont_Num32a(160, 270,RED, WHITE,rtc_initpara.year%16);
- Gui_DrawFont_Num32a(160, 240,RED, WHITE, 14);
- Gui_DrawFont_Num32a(160, 210,RED, WHITE, rtc_initpara.month/16);
- Gui_DrawFont_Num32a(160, 180,RED, WHITE,rtc_initpara.month%16);
- Gui_DrawFont_Num32a(160, 150,RED, WHITE, 14);
- Gui_DrawFont_Num32a(160, 120,RED, WHITE, rtc_initpara.date/16);
- Gui_DrawFont_Num32a(160, 90,RED, WHITE, rtc_initpara.date%16);
由于日期的显示明天才变化一次，故不宜简单的放在时间的显示函数中，否则会空浪费MCU资源。可通过对小时的数值判别来决定是否进行更新显示。
时间的显示代码则是放在时间显示函数中，该函数的内容为：
- void rtc_show_time(void)
- {
- uint32_t time_subsecond = 0;
- uint8_t subsecond_ss = 0,subsecond_ts = 0,subsecond_hs = 0;
- rtc_current_time_get(&rtc_initpara);
- /* get the subsecond value of current time, and convert it into fractional format */
- time_subsecond = rtc_subsecond_get();
- Gui_DrawFont_Num32a(200, 300,RED, WHITE, rtc_initpara.hour/16);
- Gui_DrawFont_Num32a(200, 270,RED, WHITE,rtc_initpara.hour%16);
- Gui_DrawFont_Num32a(200, 240,RED, WHITE, 11);
- Gui_DrawFont_Num32a(200, 210,RED, WHITE, rtc_initpara.minute/16);
- Gui_DrawFont_Num32a(200, 180,RED, WHITE,rtc_initpara.minute%16);
- Gui_DrawFont_Num32a(200, 150,RED, WHITE, 11);
- Gui_DrawFont_Num32a(200, 120,RED, WHITE, rtc_initpara.second/16);
- Gui_DrawFont_Num32a(200, 90,RED, WHITE, rtc_initpara.second%16);
- }
