DS3231 library

Hello. I can not find a secure library for DS3231. Because I can not uninstall the wrong library (with errors). I lose my compiler.

Help me? I owe this ...

  1. Address for bibblioteca DS 3231 original?
  2. How to remove a library with errors from the IDE compiler?

The Arduino IDE doesn't have any built-in way to remove libraries. You need to do this manually. The easiest way is (assuming the library name is DS3231):

  • File > Examples > DS3231 > select any example sketch
  • Sketch > Show sketch folder. This will open a folder something like .../DS3231/examples/DS3231example
  • Move up three folder levels.
  • Delete the DS3231 folder. Be very careful when deleting files on your computer. If in doubt back things up first.

If you don't have success finding an alternative library you might consider telling us what the problem is with your current library and we may be able to help you fix it.

Very well.

Your tip was accepted and effective.

Now I have another problem. Can you help me with this? I owe you two.

Problem:

: \ Users \ ascga_ \ Documents \ Arduino \ libraries \ DS3231 / DS3231.h: 17:22: fatal error: WProgram.h: No such file or directory

#include <WProgram.h>

^

Compilation terminated.

Open : \ Users \ ascga_ \ Documents \ Arduino \ libraries \ DS3231 / DS3231.h in a text editor
Change line 17 from:

#include <WProgram.h>

to:

#include <Arduino.h>

Save the file.

This time the result was not as expected:

#include <DS3231.h>

After your previous suggestions and even with a simple test program for DS3231 from Mr. Eric Ayars. See the error messages during compilation in detail:

Please use code tags (</> button on the toolbar) when you post code or warning/error messages. The reason is that the forum software can interpret parts of your code as markup, leading to confusion, wasted time, and a reduced chance for you to get help with your problem. This will also make it easier to read your code and to copy it to the IDE or editor. Using code tags and other important information is explained in the How to use this forum post. Please read it.

Check to be sure : \ Users \ ascga_ \ Documents \ Arduino \ libraries \ DS3231 / DS3231.h exists and that you haven't accidentally renamed it. Keep in mind that Windows Explorer hides extensions by default so if you renamed DS3231.h to DS3231.h.txt it will look like it's named DS3231.h. I recommend you to turn that option off because it's completely idiotic.
