Problem in understanding RTC

[adrianwong]

Hi, can anyone explain to me about this example in this link with details : github.com/.../main.c I'm a newbie in nordic and i found it difficult to understand this example. Kindly assist and reply asap. Thanks!

It'd be helpful to yourself and anyone responding if you could be more specific about what exactly is difficult to understand. There are only a few registers used and the product datasheet should explain most of the things sufficiently well.

Indeed - it is difficult to assist when it's not clear what assistance you require!

You say you are "a newbie in nordic" - do you have any prior programming experience at all? Do you have any prior experience with microcontrollers?

Hi , what i need is can you put details comments beside the every line of the code that i sent. Then from there i can slowly figure out what is actually happen in the code. Thanks. By the way, plus what kind of output can i expect? Currently, the code running and displayed "4, 2 , 1, 1, 1, 1, 1, 1, 1, 1, 1" by checking through serial terminal. Then it stop forever.

The comments in the code look pretty detailed already.

From the code itself, how can i change the RTC interval to 1s? THrough my calculation i couldn't get what i want. Kindly assist.
