Arduino: Using the tmElements_t structure

Projects Programming
1

I'm still a novice to C, so this is probably a silly mistake.
I'm trying to use the tmElements_t structure in the Time class.

#ifndef RTCTime_h
#define RTCTime_h

#include <Time.h>

class RTCTime
{
public:
	RTCTime();
	void setTime(tmElements_t t);
	tmElements_t getTime();
}

#endif

I get this error:

RTCTime.h : 'tmElements_t' has not been declared
RTCTime.h : 'tmElements_t' does not name a type

I am confused. Shouldn't this work? I'm importing <Time.h> at the top and Time.h contains the structure here:

typedef struct  { 
  uint8_t Second; 
  uint8_t Minute; 
  uint8_t Hour; 
  uint8_t Wday;   // day of week, sunday is day 1
  uint8_t Day;
  uint8_t Month; 
  uint8_t Year;   // offset from 1970; 
} 	tmElements_t, TimeElements, *tmElementsPtr_t;

It would be better if you uploaded the whole program, or a complete program that shows the problem.

UKHeliBob:

This demonstrates the problem, it does not compile:

#include <Time.h>

void setup()
{
  tm_Elements_t test;
}

void loop() {}

sketch_feb05a.ino: In function 'void setup()':
sketch_feb05a:6: error: 'tm_Elements_t' was not declared in this scope
sketch_feb05a:6: error: expected `;' before 'test'

tm_Elements_t exists in the Time class but it will not find it even though it's imported. "Not declared."

On the other hand, if I use time_t, it does find it:

#include <Time.h>

void setup()
{

time_t test;
}

void loop() {}

I need a time structure for my purposes though, that has hours, minutes, seconds, days months and years. Maybe I should just create one myself instead of trying to use the structure in the time class?

Ok, found the problem... I had to declare

#include <Arduino.h>
