Really good library thank you!

just a couple of additional info, may be could be useful:

  • The address 0xA0 i think should be 0xA2 from standard factoy settings
    WAS: PCF8583 p (0xA0);
    IS: PCF8583 p (0xA2);

  • I set the allarm the first time and after the allarm raise I'm not able to reset it even trying to re-set other allarm.So the interrupt remain setted.

How is it possible to reset the allarm?

Ciao,
Alan
