StampWorks Experiment #33 - Question?

MichelB

Hi all, yes I know, today is holiday, but I'll try.
In this experiment (code attached)
Button 0 -> +/- minutes
Button 1 -> +/- hours
Button 2 -> +/- day
Button 2 -> roll back
How to do to set date (day in the month, 1 - 31), month and year?
Thank you in advance for help.

This code sets the DS1307 using 12 or 24 hour mode accepting input from DEBUGIN...

The experiment obviously ignores the day of the month, month, and year. If you want to add a calendar function, use the existing code as a model. Setting day of the month, month, and year is not very different from setting minutes and hours.

Hi Mike, the code attached in my post is the original. In variables list we can see date, month and year and in Reset_Clock: date = $01 for "1st", month = $01 for "January" and year = $05 for "2005". I think (nearly sure) that to set date, month and year one must press two (2) buttons in the same time but which ones? Maybe with your great experience you can "decode" which ones.

P.S.: Behind the Scenes, ... This is especially true when an application needs to handle time, day and date. StampWorks Page 194.

It looks like Button 0 and Button 1.

Reset_Clock:
  GOSUB Get_Buttons                             ' scan buttons
  [color=red]idx = btns & %0011[/color]                            ' isolate hrs & mins
  IF (idx = %11) THEN                           ' if both pressed, reset
    secs = $00
    mins = $00
    hrs = $06                                   ' 6:00 AM
    day = $07                                   ' Saturday
    date = $01                                  ' 1st
    month = $01                                 ' January
    year = $05                                  ' 2005
    control = 0                                 ' disable SQW output
    GOSUB Set_Clock                             ' block write clock regs
  ENDIF
