Hi all,
I just want to make sure if this is how clock with 1307 works.
So time keeping is entirely done by 1307. First I need to initialize it, run the oscilator then I just need to setup communication with it to read the time, display it, loop it until some one adjust the time and save it to 1307 ?

Haven't figure out the matrix led yet :D
But I'll try to implement 1307 first.
I loooveeee the battery backup thing.
