Errors with DS3231 Libraries

system · August 3, 2012, 9:22pm

I have read all the posts here and found a lot of usefull stuff. I am using IDE 1.0.1 on a Modern Devices RBBB.
However, I still can't get any of the DS3231 examples to compile and run. I keep getting the following errors;

ds3231_set:128: error: redefinition of 'DS3231 Clock'
ds3231_set:14: error: 'DS3231 Clock' previously declared here
ds3231_set:130: error: redefinition of 'byte Year'

Would appreciate any help..........Thanks

Looks like the sketch contains everything twice. Perhaps if you showed your sketch it would be easier to figure out what's wrong.

Sure, it's the example sketch from the DS3231 Library

/*

Turn on the serial monitor after loading this to check if things are
working as they should.

Which library? Does it contain both PDE and INO example sketches? Do you have two tabs showing in the IDE?

system · August 6, 2012, 12:31pm

It's the DS3231 Library, and the examples are in .pde ..................

system · August 6, 2012, 12:42pm

It's the DS3231 Library

Which you got from where?

system · August 6, 2012, 12:58pm

From the Eric Ayers Web site. Hardware Hacks: DS3231 Real-Time Clock

system · August 6, 2012, 1:18pm

It compiles ok under IDE 023. The library, as downloaded, isn't compatible with 1.0+. What changes have you made?

system · August 6, 2012, 1:38pm

I haven't made any changes! I tried all 3 examples included with the download, and get numerous errors each time.

system · August 6, 2012, 1:46pm

Well, that library isn't compatible with IDE 1.0 or later. You have a number of options.

Use a different library that is compatible.
Contact the author, and see if they will update it.
Update it yourself.

For some reason, the 'WProgram.h missing' error that you get if you try a to compile this under 1.0 is hidden under 1.0.1.

Hi,

Is this link helpful?

Tried all those tips and still no joy!

system · August 6, 2012, 2:29pm

Then try a different library. arduino ds3231 library - Google Search

Riva · August 6, 2012, 5:11pm

This now compiles ok under 1.0.1

DS3231.zip (9.29 KB)

johnwasser · August 6, 2012, 7:19pm

To fix the Eric Ayers DS3231 library:

In DS3231.h:
Change <Wprogram.h> to <Arduino.h>

In DS3231.cpp:
Replace all "Wire.send" with "Wire.write".
Replace all "Wire.receive" with "Wire.read".

After that the DS3231_test example compiles without error.

system · August 7, 2012, 7:58pm

Thanks to all, I finally got my code to run, with IDE0023.............

I'm confused now (something that can easily happen :D) as I thought you wanted the library to compile and work under 1.0.1 as it was originally written for 0.23
