复制代码 虽然可以达到数字时钟的效果,但是当翻页的时候,时钟就会被清除重新计数," z7 O1 [5 x6 k# e3 z
项目用FREERTOS开发,在里面设置进程间通信特别复杂,要解决这个问题,更快捷的方法是在这部分中添加RTC时钟。8 V& T: r$ f" h v: K
在RTC中使能并设定好时间:. N7 f. u( l8 T
, k+ K6 l" C" F+ X3 z% f对应的程序也要需要重写一下:
5 x. j/ z5 \" b ~首先要在modelListener.hpp里添加RTC相关函数:( o% t6 r2 a7 ~
- virtual void updateTime(uint8_t hour, uint8_t minute, uint8_t second) {}
复制代码 然后,在MODEL.C中,把主函数的RTC TIME和DATE拉过来(注意要两个一起,不然会有BUG),并传参给updateTime函数。/ H% O* S l2 Z: [
- extern RTC_TimeTypeDef RTC_Time;
- K% n' M2 L7 \3 A0 r - extern RTC_DateTypeDef RTC_Date;! {& o* Q, f4 m7 o5 e; }9 R, q

- }
9 R$ h1 b$ h; l5 _
复制代码 不要忘了在time里也要再定义一次updateTime函数:
2 M: q1 X8 m- ?; T/ r, J1 O- void timePresenter::updateTime(uint8_t hour,uint8_t minute,uint8_t second)2 U/ m3 o. p7 x7 g/ s

- view.updateTime(hour,minute,second);5 [; \% D4 S% h! {- a, {, B+ ]
- }3 A( ^: M# ~) u! `
复制代码 对应的.hpp文件也要定义一次:
+ k4 z- F$ @5 |( @4 c" b$ A9 g- void updateTime(uint8_t hour,uint8_t minute,uint8_t second); c3 K' ?6 d7 w
复制代码 最后,在screenView.C中修改,把其他几个全部注释掉,只留存累加器,并在开始累计之前就获取一次时间) `& q, o% T$ v2 V0 D
