Digital Clock for PIC16F628A

[Vasil97]

I am trying to do a 7segment, digital clock at the moment. I'm using Pic16F628A and the segments are TIL311. I use external clock OSC 32768Hz, 3 buttons, external reset, a speaker for alarm and a red LED for a decimal point. The core of the program has already been made and I have tested it. The timer interupt works and so does the visualise sub-program, soo at the moment i have a working clock that can't be synchronized and has no alarm. But from a few days I am stuck at the part with the synchronization and the alarm.

My idea is i press the first button once and synchronize the clock. I press it for a second time and synchronize the alarm time. When i press the button for a third time i save everything. The problem is that i can't think of a way to realize that idea. Can you help me or give me a better idea?

But think, If you want to just set the Alarm.
How do you perform it ?

The ultimate thing is --how user friendly it will be.

You can add a button to enter mode of operation, another two for increase time and decrease time(both clock time and alarm time) another for save and exit mode.

Also you can add snooz and mute alarm upon these buttons
