ESP32（8）：RTC时钟_esp32cam设置rtc时间

一、ESP32Cam引脚图

二、ArduinoIDE程序编写

ESP32Time.h该文件需要进行安装

public.h

#ifndef _public_H
#define _public_H
 
#include "Arduino.h"
 
//类型重定义
typedef unsigned char u8;
typedef unsigned int u16;
typedef unsigned long u32;
 
#endif

main.c

#include "public.h"
#include <ESP32Time.h>
 
ESP32Time rtc(3600);  // offset in seconds GMT+1
 
void setup(){
  Serial.begin(115200);
  rtc.setTime(30, 24, 15, 17, 9, 2022);//2022年9月17日15点24分30秒
}
 
void loop(){
  //  Serial.println(rtc.getTime());          //  (String) 15:24:38
  //  Serial.println(rtc.getDate());          //  (String) Sun, Jan 17 2021
  //  Serial.println(rtc.getDate(true));      //  (String) Sunday, January 17 2021
  //  Serial.println(rtc.getDateTime());      //  (String) Sun, Jan 17 2021 15:24:38
  //  Serial.println(rtc.getDateTime(true));  //  (String) Sunday, January 17 2021 15:24:38
  //  Serial.println(rtc.getTimeDate());      //  (String) 15:24:38 Sun, Jan 17 2021
  //  Serial.println(rtc.getTimeDate(true));  //  (String) 15:24:38 Sunday, January 17 2021
  //
  //  Serial.println(rtc.getMicros());        //  (long)    723546
  //  Serial.println(rtc.getMillis());        //  (long)    723
  //  Serial.println(rtc.getEpoch());         //  (long)    1609459200
  //  Serial.println(rtc.getSecond());        //  (int)     38    (0-59)
  //  Serial.println(rtc.getMinute());        //  (int)     24    (0-59)
  //  Serial.println(rtc.getHour());          //  (int)     3     (0-12)
  //  Serial.println(rtc.getHour(true));      //  (int)     15    (0-23)
  //  Serial.println(rtc.getAmPm());          //  (String)  pm
  //  Serial.println(rtc.getAmPm(true));      //  (String)  PM
  //  Serial.println(rtc.getDay());           //  (int)     17    (1-31)
  //  Serial.println(rtc.getDayofWeek());     //  (int)     0     (0-6)
  //  Serial.println(rtc.getDayofYear());     //  (int)     16    (0-365)
  //  Serial.println(rtc.getMonth());         //  (int)     0     (0-11)
  //  Serial.println(rtc.getYear());          //  (int)     2021
  
  //  Serial.println(rtc.getLocalEpoch());         //  (long)    1609459200 epoch without offset
 
  Serial.println(rtc.getTime("%A, %B %d %Y %H:%M:%S"));   // (String) returns time with specified format 
  // formating options  http://www.cplusplus.com/reference/ctime/strftime/
  delay(1000);
}

最后就可以通过串口查看时间信息。
