Chronodot library update for 1.0

[stephanie]

For what it's worth, I've just updated my little Chronodot library for Arduino 1.0 compatibility.

I've also set it to maintain backwards compatibility with the older IDEs, just in case folks want to keep using them.

Someday I will learn how to use Git... If only there were some sort of achievement badge I could earn, to nudge me along...

Cheers!

Edited to add: the only advantage this offers over the DS1307 library, is this one lets you access the Chronodot's built-in temperature sensor - you can get tempF and tempC in addition to the date and time info.

Nice work Stephanie! If I only had a badge to give you

Today is the day I learned how to use github!

I have set up a proper repository for the library here:

Cheers!

I'm finishing up some extra documentation for the ChronoDot and will definitely be linking your library. I will be posting a big mess o' functions too, so people can see how things are done. But will recommend that everyone just use your library or the Time library if they have the space.

Wow neat!

I know the DS3231 is capable of a few more features -- like the dual alarms, that I completely ignored when I set that up. I was really just focused on getting the temperature data out of it, but I've been reading the datasheet and thinking of adding more capabilities to the library. No idea when I'd get to it though, it's been on my todo for some time already.

Cheers!

I don't think alarms are useful in the context of the Arduino, since no one ever does sleep-mode stuff with that. It's just as easy to check the time frequently and be able to calculate many different alarm times. Plus you don't have to wire another pin over, you can keep square wave output if you need it, and you don't have to check a register for alarm interrupt flags. I'm not putting in demo code that uses the alarms. It would be useful if you had a very low power application and you needed to wake up the MCU after weeks or months of inactivity. So don't worry about ignoring the alarms for now, I don't think you're missing much
