依稀记得stm32f10x系列的rtc需要自己把秒转换成年、月、日、时、分、秒，今天我们来试试es32f369的rtc，用起来很简单，配置好参数后，直接输出时间和日期，还可以根据自己的喜好设置12小时制还是24小时制。
在上节【东软载波ES32F369x+驱动0.96OLED】的基础上进行扩展，实时显示RTC。
核心代码
- #include "periph_rtc.h"
- #include "md_bkpc.h"
- #include "md_rtc.h"
-
- md_rtc_time_t time;
- md_rtc_date_t date;
- void RTC_Init()
- {
- md_rtc_init_t init;
- /* Set LOSM as RTC clock */
- // md_bkpc_rtc_clock_config(MD_BKPC_PREH_CLK_LOSM);
- /* Initialize RTC */
- md_rtc_struct_init(&init);
- md_rtc_init(&init);
-
- /* Initialize time/date */
- md_rtc_time_struct_init(&time);
- md_rtc_date_struct_init(&date);
-
- date.year=21;
- date.month=1;
- date.day=23;
- date.week=6;
-
- time.hour=19;
- time.minute=11;
- time.second=30;
- time.sub_sec=10;
-
- md_rtc_set_time(&time, MD_RTC_FORMAT_DEC);
- md_rtc_set_date(&date, MD_RTC_FORMAT_DEC);
- }
- /*
- uint8_t hour;
- uint8_t minute;
- uint8_t second;
- uint16_t sub_sec;
- uint8_t week;
- uint8_t day;
- uint8_t month;
- uint8_t year;
- */
- void Get_Rtc(uint8_t *buff)
- {
- md_rtc_get_time(&time, MD_RTC_FORMAT_DEC);
- md_rtc_get_date(&date, MD_RTC_FORMAT_DEC);
-
- buff[0]=date.year;
- buff[1]=date.month;
- buff[2]=date.day;
- buff[3]=date.week;
-
- buff[4]=time.hour;
- buff[5]=time.minute;
- buff[6]=time.second;
- }
循环获取时间和日期：
- while (1)
- {
- md_delay_1ms(400);
-
- md_gpio_set_pin_low(GPIOF, MD_GPIO_PIN_0);
- md_gpio_set_pin_low(GPIOF, MD_GPIO_PIN_1);
-
- md_delay_1ms(400);
- md_gpio_set_pin_high(GPIOF, MD_GPIO_PIN_0);
- md_gpio_set_pin_high(GPIOF, MD_GPIO_PIN_1);
- Get_Rtc(buff);
-
- OLED_ShowCN(40,1,4);
- OLED_ShowCN(56,1,5);
- OLED_ShowCN(72,1,buff[3]+5);
-
- memset(str,' ',sizeof(str));
- sprintf(str,"20%02d-%02d-%02d",buff[0],buff[1],buff[2]);
- OLED_ShowString(24,3,str,16);
-
- memset(str,' ',sizeof(str));
- sprintf(str,"%02d:%02d:%02d",buff[4],buff[5],buff[6]);
-
- OLED_ShowString(32,5,str,16);
- }
发现论坛传不了视频。。。
