Help changing time on RTC1307 with buttons

i have had trouble finding changing time on rtc few buttons (set, hour, min). making large scale clock arduino mega 2560.  i have set except being able change time on clock without having reconnect computer.  i working on calling each minute, have been trying figure out time change issue.

you can 1 button... , few states

check long button press - start timer when button pressed more  7 seconds

then press press press change hour... 7 seconds of inactivity change allow set minutes... press press press... 7 seconds without change... returns ignoring set cycle

something this, need put program.

just put pushbutton on pin3 , ground...

try on own first, notice led13 change rate set hours , minutes...

code: [select]


int pushbutton = 3;
unsigned long settime = 7000ul;
unsigned long timerstart;
int state = 0;
int buttonstate, lastbuttonstate;
unsigned long lastflash;

void setup()
{
 serial.begin(115200);
 pinmode(pushbutton, input_pullup);
  pinmode(13, output);
}

void loop()
{
 if (state == 0)
 {
   flash(1000);
   buttonstate = digitalread(pushbutton);
   if (buttonstate == low) //button pressed
   {
     if (lastbuttonstate == high) // button state changed
     {
       timerstart = millis();
     }
     else if (millis() - timerstart >= settime)//held settime
     {
       state = 1;
       timerstart = millis();
       serial.print(f("setting hour"));
     }
   }
   lastbuttonstate = buttonstate;
 }
 else if (state == 1)// set hour
 {
   flash(50);
   buttonstate = digitalread(pushbutton);
   if (buttonstate == low && lastbuttonstate == high)
   {
     timerstart = millis();
     //add 1 hour rtc here
     serial.print(f("one hour added!!!"));
   }
   lastbuttonstate = buttonstate;
   if (millis() - timerstart >= settime)
   {
     state = 2;// timed out
     timerstart = millis();
     serial.print(f("setting minute"));
   }
 }
 else if (state == 2)// set minute
 {
   flash(250);
   buttonstate = digitalread(pushbutton);
   if (buttonstate == low && lastbuttonstate == high)//only on button change
   {
     timerstart = millis();
     //add 1 minute rtc here
     serial.print(f("one minute added!!!"));
   }
   lastbuttonstate = buttonstate;
   if (millis() - timerstart >= settime)
   {
     state = 0;// timed out
     timerstart = millis();
     serial.print(f("completed setting time"));
   }
 }
 //
 //your clock loop() function goes here
 //
}

void flash(unsigned long rate)
{
 if (millis() - lastflash > rate)
 {
   digitalwrite(13, !digitalread(13));
   lastflash = millis();
 }
