Hi everybody, I'm trying to make this function working, all timers in this library work, but not Alarm.alarm.Repeat().
I look the serial if the event prints but none. Anyone knows why?
I took the main example of this library and just added some things.
here's my code
#include <Time.h>
#include <TimeAlarms.h>
#define TIME_MSG_LEN 11 // time sync to PC is HEADER followed by Unix time_t as ten ASCII digits
#define TIME_HEADER 'T' // Header tag for serial time sync message
#define TIME_REQUEST 7 // ASCII bell character requests a time sync message
void setup()
{
Serial.begin(9600);
//setTime(8,29,0,1,1,10); // set time to 8:29:00am Jan 1 2010
// create the alarms
Alarm.alarmRepeat(8,30,0, MorningAlarm); // 8:30am every day
Alarm.alarmRepeat(21,34,0,EveningAlarm); // 5:45pm every day
//Alarm.timerRepeat(15, Repeats); // timer for every 15 seconds
//Alarm.timerOnce(10, OnceOnly); // called once after 10 seconds
}
void loop(){
if(Serial.available() )
{
processSyncMessage();
}
if(timeStatus() == timeNotSet)
Serial.println("waiting for sync message");
else
digitalClockDisplay();
Alarm.delay(1000);
}
// functions to be called when an alarm triggers:
void MorningAlarm(){
Serial.println("Alarm: - turn lights off");
}
void EveningAlarm(){
Serial.println("Alarm: - turn lights on");
}
void Repeats(){
Serial.println("15 second timer");
}
void OnceOnly(){
Serial.println("This timer only triggers once");
}
void digitalClockDisplay(){
// digital clock display of the time
Serial.print(hour());
printDigits(minute());
printDigits(second());
Serial.print(" ");
Serial.print(day());
Serial.print(" ");
Serial.print(month());
Serial.print(" ");
Serial.print(year());
Serial.println();
}
void printDigits(int digits)
{
Serial.print(":");
if(digits < 10)
Serial.print('0');
Serial.print(digits);
}
void processSyncMessage() {
// if time sync available from serial port, update time and return true
while(Serial.available() >= TIME_MSG_LEN ){ // time message consists of header & 10 ASCII digits
char c = Serial.read() ;
Serial.print(c);
if( c == TIME_HEADER ) {
time_t pctime = 0;
for(int i=0; i < TIME_MSG_LEN -1; i++){
c = Serial.read();
if( c >= '0' && c <= '9'){
pctime = (10 * pctime) + (c - '0') ; // convert digits to a number
}
}
setTime(pctime); // Sync Arduino clock to the time received on the serial port
}
}
}

(still thinking it's not very nice, but it works! if anyone knows how to improve this code and want to share his knowledge...
what is a callback function? I use alarm.delay because I've read that I need it instead of normal delay for use the alarms functions
here's my code updated and cleaned
#include <Time.h>
#include <TimeAlarms.h>
#define TIME_MSG_LEN 11 // time sync to PC is HEADER followed by Unix time_t as ten ASCII digits
#define TIME_HEADER 'T' // Header tag for serial time sync message
#define TIME_REQUEST 7 // ASCII bell character requests a time sync message
int relePin = 8;
void setup()
{
pinMode(relePin, OUTPUT);
Serial.begin(9600);
// test relè and motors
int a=0;
while(!Serial.available()){
Alarm.delay(10);
}
if(Serial.available() && a==0){
testMotors();
a++;
}
while(timeStatus() == timeNotSet){
if(Serial.available() && timeStatus() == timeNotSet){
processSyncMessage();
}
if(timeStatus() == timeNotSet)
Serial.println("waiting for sync message");
else
digitalClockDisplay();
Alarm.delay(1000);
}
Alarm.alarmRepeat(18,10,0, MorningAlarm); // 7:00am every day
Alarm.alarmRepeat(7,10,0, MorningAlarm); // 7:10am every day
//Alarm.alarmRepeat(20,0,0,EveningAlarm); // 20pm every day
//Alarm.timerRepeat(15, Repeats); // timer for every 15 seconds
//Alarm.timerOnce(10, OnceOnly); // called once after 10 seconds
}
void loop(){
if(timeStatus() == timeNotSet)
Serial.println("waiting for sync message");
else
digitalClockDisplay();
Alarm.delay(1000);
}
void testMotors(){
int i, reduce;
Serial.println("armando il motore...");
Alarm.delay(3000);
for(i=0, reduce=2000;i<10, reduce>=400;i++){
digitalWrite(relePin, HIGH);
Alarm.delay(reduce);
digitalWrite(relePin, LOW);
Alarm.delay(reduce);
digitalWrite(relePin, HIGH);
Alarm.delay(reduce);
digitalWrite(relePin, LOW);
Alarm.delay(reduce);
reduce/=2;
}
Serial.println("motore armato!");
}
void accendiMotori(){
digitalWrite(relePin, HIGH);
Alarm.delay(40000);
digitalWrite(relePin, LOW);
}
// functions to be called when an alarm triggers:

}
void processSyncMessage() {
// if time sync available from serial port, update time and return true
while(Serial.available() >= TIME_MSG_LEN ){ // time message consists of header & 10 ASCII digits
char c = Serial.read() ;
Serial.print(c);
if( c == TIME_HEADER ) {
time_t pctime = 0;

}
It's a delegate - a way to tell another function to do something using code you write. When the alarm goes off, you want the Alarm class to call your function (MorningAlarm or EveningAlarm). So, you tell the instance which function to call(back) when it has something to do.
