ds3231 and time libraries

Using Arduino Programming Questions
1

Hello:

I am having no luck at all getting the time library examples to run. Have tried many different ones, but always get errors- lots of errors. Believe the issue may be that the libraries were written for 1.0, but I have 1.05-r2. Not finding much help on specifically how to correct. About ready to abandon the project, frustrated.

Thanks

Mark

What time libraries are you talking about?

3

What sorts of errors?

You could try reading and following the instructions, like the ones that tell you how to post here (you have seen them - there the ones in the eye watering red at the top of the forum) or the ones on how to install a lib.

Hi:

Library is ds3231.

Errors seen are "byte has not been declared"

Example that was tried is DS3231_test.

Other libraries/examples such as to test the LCD I have connected are successful.

Thanks

Mark

Library is ds3231.

That is not helpful. Can you provide a link?

I concur. A google search for "arduino," "library," "ds3231" yields a huge array of hits. I'm not willing to try and guess which one you picked.

At this link - Programming Questions - Arduino Forum, the entry into the "Programming Questions" section of this forum, you'll find, at the top of the list of posts, an entry entitled, "How to use this forum - please read." Please read it, follow the link, and do what it suggests. In particular, these entries from item #11, "Tips for getting the most out of your post," are particularly relevant to your question:

  • Mention which Arduino you have.
  • Post a complete sketch (program code)! If you don't you waste time while people ask you to do that. However, with coding problems, if possible post a "minimal" sketch that demonstrates the problem - not hundreds of lines of code. If the problem goes away in the minimal sketch, it wasn't where you thought it was.
  • If you get an error, post the error (copy and paste). Not just "I got an error".
  • If you are using a library that does not come with the IDE (in other words, you downloaded it from somewhere) please post a link to this library.
    [emphasis mine]

I think that it would be a trivial effort for you to name your Arduino, post a short sketch that illustrates your problem, post the errors, and post a link to the library.

Figuring out what's wrong with your code can be a lot of work. We'll help, if you'll do most of it.
