example code for DS1337

[Darrel Taylor]

John,

I'm not sure which pin you've connected SQW to, but ...

      TRISA =%00000000 
      TRISB =%00000000 
      TRISC =%00000000 
      TRISD =%00000000

One of the first things you do is set almost all the pins to output.
That would stop any signal from SQW.

If you think it is a capacitor issue and you are ordering more parts you may want to look at the DS1337C. Everything is built in.

What voltage are you running the RTC on?

I seem to be having a lot of senior moments lately...this being another one. I should have caught that....once I set TRISB to provide for inputs on the pins I had connected to SQW/_INTB and _INTA the alarms worked as intended, thus indicating to me that current time and alarms were being correctly set at programming time even though I couldn't see that they were because of lack of a LCD.
Thanks again Darrel!
