代码收藏家 STM32 TouchGFX【六】实现时间显示
使用TouchGFX显示当前时间
TouchGFX配置
拖入文本框
更改通配符选项 先修改年
填入默认数字和字符缓冲大小 大于显示字符即可
TouchGFX中时间的字体类型一定要设置范围 否则显示不正常
Cubemx配置
打开RTC添加 日历
添加一个TIM用来刷新时间
添加代码
app_user.c
gTask_MarkEN gTaskEnMark; //系统任务使能标识
//系统时间
RTC_DateTypeDef gSystemDate; //获取日期结构体
RTC_TimeTypeDef gSystemTime; //获取时间结构体
/* The sensors can be mounted onto the board in any orientation. The mounting
* matrix seen below tells the MPL how to rotate the raw data from thei
* driver(s).
* TODO: The following matrices refer to the configuration on an internal test
* board at Invensense. If needed, please modify the matrices to match the
* chip-to-body matrix for your particular set up.

#endif
void Model::tick()
{
static uint8_t tickCount = 0; //减少数据上传的次数，优化界面刷新
tickCount++;
#if defined LINK_HARDWARE
//更新日期与时间
if(gSystemTime.Seconds != gLastTimeSeconds) //每秒同步一次界面时间
{
modelListener->updateDate(gSystemDate.Year,gSystemDate.Month,gSystemDate.Date,gSystemDate.WeekDay);
modelListener->updateTime(gSystemTime.Hours, gSystemTime.Minutes, gSystemTime.Seconds);
//更新新值
gLastTimeSeconds = gSystemTime.Seconds;
}
#endif
}
keil添加一个宏来实现前后端的分离 ，这样TouchGFX软件仿真不会报错
presenter.cpp
//更新日期
void screenPresenter::updateTime(uint8_t newHours, uint8_t newMinutes, uint8_t newSeconds)
{
view.updateTime(newHours, newMinutes, newSeconds);
}
void screenPresenter::updateDate(uint8_t newYear, uint8_t newMonth, uint8_t newDate, uint8_t newWeekDay)
{
view.updateDate(newYear, newMonth, newDate, newWeekDay);
}
View.cpp
void screenView::updateTime(uint8_t newHours, uint8_t newMinutes, uint8_t newSeconds)
{
Unicode::snprintf(TimeClockBuffer1, TIMECLOCKBUFFER1_SIZE, "%02d", newHours);
Unicode::snprintf(TimeClockBuffer2, TIMECLOCKBUFFER2_SIZE, "%02d", newMinutes);
TimeClock.invalidate();
Unicode::snprintf(TimeSecondBuffer, TIMESECOND_SIZE, "%02d", newSeconds);
TimeSecond.invalidate();
}
//更新日期
void screenView::updateDate(uint8_t newYear, uint8_t newMonth, uint8_t newDate, uint8_t newWeekDay)
{
Unicode::snprintf(TimeyearBuffer, TIMEYEAR_SIZE, "%04d", newYear + 2000);
Timeyear.invalidate();
//
Unicode::snprintf(TimeDataBuffer1, TIMEDATABUFFER1_SIZE, "%02d", newMonth);
Unicode::snprintf(TimeDataBuffer2, TIMEDATABUFFER2_SIZE, "%02d", newDate);
TimeData.invalidate();
//
}
实验结果
注意事项 下载后要重新上电否则 时间不更新 并且下载需要重新编译来获取当前时间
