動作確認

のTimeライブラリ使用

上記のライブラリを使用してESP8266の日時設定をする。
setTime()という関数があるようだ。

Functions for managing the timer services are:
setTime(t); // set the system time to the give time t
setTime(hr,min,sec,day,mnth,yr); // alternative to above, yr is 2 or 4 digit yr (2010 or 10 sets year to 2010)

eps8266_160619_timeLib.ino
#include <TimeLib.h>
#include <stdarg.h>

void setup() {

#if 1
  setTime(9, 43, 0, 19, 6, 2016);
#else
  setTime(86400); 
#endif  
   
  Serial.begin(115200);
}

void myPrintf(char *fmt, ...) 
{
  char buf[128];
  va_list args;
  va_start(args, fmt);
  vsnprintf(buf, 128, fmt, args);
  va_end(args);
  Serial.print(buf);  
}

void loop() {
  myPrintf("%02d:%02d:%02d", hour(), minute(), second() );
  myPrintf(",%02d/%02d/%04d", day(), month(), year() );
  Serial.println(); 

  delay(3000);
}
