通过H7S7L8H6H RTC获取时间，并通过TouchGFX analogClock、digitalClock显示出来。
一、TouchGFX配置
增加一个Screen，放置几个部件，其中包含：analogClock1、digitalClock1
F4->生成代码。
二、STM32CubeMX配置
配置RCC，高低速时钟均为外部时钟
配置RTC：
生成代码
三、代码修改
1、RTC初始化
- static void MX_RTC_Init(void)
- {
- /* USER CODE BEGIN RTC_Init 0 */
- /* USER CODE END RTC_Init 0 */
- RTC_PrivilegeStateTypeDef privilegeState = {0};
- //RTC_TimeTypeDef sTime = {0};
- //RTC_DateTypeDef sDate = {0};
- /* USER CODE BEGIN RTC_Init 1 */
- /* USER CODE END RTC_Init 1 */
- /** Initialize RTC Only
- */
- hrtc.Instance = RTC;
- hrtc.Init.HourFormat = RTC_HOURFORMAT_24;
- hrtc.Init.AsynchPrediv = 127;
- hrtc.Init.SynchPrediv = 255;
- hrtc.Init.OutPut = RTC_OUTPUT_DISABLE;
- hrtc.Init.OutPutRemap = RTC_OUTPUT_REMAP_NONE;
- hrtc.Init.OutPutPolarity = RTC_OUTPUT_POLARITY_HIGH;
- hrtc.Init.OutPutType = RTC_OUTPUT_TYPE_OPENDRAIN;
- hrtc.Init.OutPutPullUp = RTC_OUTPUT_PULLUP_NONE;
- hrtc.Init.BinMode = RTC_BINARY_NONE;
- if (HAL_RTC_Init(&hrtc) != HAL_OK)
- {
- Error_Handler();
- }
- privilegeState.rtcPrivilegeFull = RTC_PRIVILEGE_FULL_NO;
- privilegeState.backupRegisterPrivZone = RTC_PRIVILEGE_BKUP_ZONE_NONE;
- privilegeState.backupRegisterStartZone2 = RTC_BKP_DR0;
- privilegeState.backupRegisterStartZone3 = RTC_BKP_DR0;
- if (HAL_RTCEx_PrivilegeModeSet(&hrtc, &privilegeState) != HAL_OK)
- {
- Error_Handler();
- }
- /* USER CODE BEGIN Check_RTC_BKUP */
- /* USER CODE END Check_RTC_BKUP */
- /** Initialize RTC and set the Time and Date
- */
- sTime.Hours = 0x0;
- sTime.Minutes = 0x0;
- sTime.Seconds = 0x0;
- sTime.DayLightSaving = RTC_DAYLIGHTSAVING_NONE;
- sTime.StoreOperation = RTC_STOREOPERATION_RESET;
- if (HAL_RTC_SetTime(&hrtc, &sTime, RTC_FORMAT_BCD) != HAL_OK)
- {
- Error_Handler();
- }
- sDate.WeekDay = RTC_WEEKDAY_MONDAY;
- sDate.Month = RTC_MONTH_JANUARY;
- sDate.Date = 0x1;
- sDate.Year = 0x0;
- if (HAL_RTC_SetDate(&hrtc, &sDate, RTC_FORMAT_BCD) != HAL_OK)
- {
- Error_Handler();
- }
- /* USER CODE BEGIN RTC_Init 2 */
- /* USER CODE END RTC_Init 2 */
- }
- RTC_TimeTypeDef sTime = {0};
- RTC_DateTypeDef sDate = {0};
2、model.cpp
这里一定要加上：HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN);，虽然没有用。不加，HAL_RTC_GetTime也无法获得时间。
- extern RTC_HandleTypeDef hrtc;
- extern RTC_TimeTypeDef sTime;
- extern RTC_DateTypeDef sDate;
- void Model::tick()
- {
- static uint8_t tick=0;
- tick++;
- if(tick%60==0)
- {
- HAL_RTC_GetTime(&hrtc, &sTime, RTC_FORMAT_BIN);
- HAL_RTC_GetDate(&hrtc, &sDate, RTC_FORMAT_BIN);
- modelListener->updateTime(sTime.Hours,sTime.Minutes,sTime.Seconds);
- printf( "%2d:%2d:%2d\r\n", sTime.Hours, sTime.Minutes, sTime.Seconds);
- tick=0;
- }
- }
- #ifndef MODELLISTENER_HPP
- #define MODELLISTENER_HPP
- #include <gui/model/Model.hpp>
- class ModelListener
- {
- public:
- ModelListener() : model(0) {}
-
- virtual ~ModelListener() {}
-
- virtual void uart4Updated();
-
- virtual void updateTime(unsigned char newHours, unsigned char newMinutes, unsigned char newSeconds);
- void bind(Model* m)
- {
- model = m;
- }
- protected:
- Model* model;
- };
- #endif // MODELLISTENER_HPP
- void Screen4Presenter::updateTime(unsigned char newHours, unsigned char newMinutes, unsigned char newSeconds)
- {
- view.updateTime(newHours, newMinutes, newSeconds);
- }
- void Screen4View::updateTime(unsigned char newHours, unsigned char newMinutes, unsigned char newSeconds)
- {
- analogClock1.setTime24Hour(newHours,newMinutes,newSeconds);
- digitalClock1.setTime24Hour(newHours,newMinutes,newSeconds);
- }
- void HAL_RTC_MspInit(RTC_HandleTypeDef* hrtc)
- {
- RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
- if(hrtc->Instance==RTC)
- {
- /* USER CODE BEGIN RTC_MspInit 0 */
- HAL_PWR_EnableBkUpAccess();
- /* USER CODE END RTC_MspInit 0 */
四、效果
1、屏幕效果
2、串口输出：
3、视频：
五、总结
1、感谢南来之风 https://bbs.21ic.com/icview-3400954-1-1.html排雷，否则不知道要在RTC初始化卡多久。
2、TouchGFX CLOCK+RTC可以参考：https://www.bilibili.com/video/BV1pp421U7gK/?spm_id_from=333.337.search-card.all.click&vd_source=5b0f94f2f57c38a43471771787964a99
