SetTime()
Description:
Sets the time of a structure variable
Syntax:
void SetTime(RTC_TimeTypeDef* RTC_TimeStruct)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12
#include <M5StickC.h> RTC_TimeTypeDef TimeStruct;void setup() { M5.begin(); TimeStruct.Hours = 18; TimeStruct.Minutes = 56; TimeStruct.Seconds = 10; M5.Rtc.SetTime(&TimeStruct);}void loop(){};GetTime()
Description:
Gets the time from a structure
Syntax:
void GetTime(RTC_TimeTypeDef* RTC_TimeStruct)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
#include <M5StickC.h> RTC_TimeTypeDef TimeStruct;void setup() { M5.begin(); M5.Lcd.setRotation(3); M5.Lcd.fillScreen(BLACK); M5.Lcd.setTextSize(1); M5.Lcd.setCursor(40, 0, 2); M5.Lcd.println("RTC TEST"); TimeStruct.Hours = 18; TimeStruct.Minutes = 56; TimeStruct.Seconds = 10; M5.Rtc.SetTime(&TimeStruct);} void loop() { M5.Rtc.GetTime(&TimeStruct); M5.Lcd.setCursor(0, 15); M5.Lcd.printf("Time: %02d : %02d : %02d/n",TimeStruct.Hours, TimeStruct.Minutes, TimeStruct.Seconds); delay(500);}SetDate()
Description:
Sets the date of a structure variable
Syntax:
void SetDate(RTC_TimeTypeDef* RTC_DateStruct)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14
#include <M5StickC.h> RTC_TimeTypeDef TimeStruct;RTC_DateTypeDef DateStruct;void setup() { M5.begin(); DateStruct.WeekDay = 3; DateStruct.Month = 3; DateStruct.Date = 22; DateStruct.Year = 2019; M5.Rtc.SetDate(&DateStruct);}void loop(){};GetDate()
Description:
Gets the date from a structure variable
Syntax:
void GetDate(RTC_TimeTypeDef* RTC_DateStruct)
Example:
cpp
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26
#include <M5StickC.h> RTC_DateTypeDef DateStruct;void setup() { M5.begin(); M5.Lcd.setRotation(3); M5.Lcd.fillScreen(BLACK); M5.Lcd.setTextSize(1); M5.Lcd.setCursor(40, 0, 2); M5.Lcd.println("RTC TEST"); DateStruct.WeekDay = 3; DateStruct.Month = 3; DateStruct.Date = 22; DateStruct.Year = 2019; M5.Rtc.SetDate(&DateStruct);} void loop() { M5.Rtc.GetDate(&DateStruct); M5.Lcd.setCursor(0, 15); M5.Lcd.printf("Date:%04d-%02d-%02d/n",DateStruct.Year, DateStruct.Month,DateStruct.Date); M5.Lcd.printf("Week:%d/n",DateStruct.WeekDay); delay(500);}
