Old weather station still running but program won't now compile

spiney · July 25, 2026, 10:06am

I wanted to edit this weather station code which has been running for years, but the old unedited code won't verify, giving these errors. The error appears in line 138.

Please edit your post, select the text of the whole sketch then click on the < CODE > icon to add code tags and then save the post

Better still, use Tools/Auto Format in the IDE and post the sketch in code tags

J-M-L · July 25, 2026, 10:26am

@spiney actually had the code tags but the first part got garbled as the tags were not in their own line by themselves. I fixed it.

J-M-L · July 25, 2026, 10:31am

The error comes from the version of the SD library currently installed, which no longer accepts the four-argument syntax SD.begin(10, 11, 12, 13). In recent versions of SD.h you would typically use the overload SD.begin(uint8_t csPin) so only the CS pin should be passed.

That line also has an unrelated bug:

the semicolon right after the closing parenthesis makes the if statement empty, so error("Cd fail") runs unconditionally regardless of whether the SD card actually initialized.

The fix, using the chipSelect constant already defined earlier in the code, is:

if (!SD.begin(chipSelect)) error("Cd fail");

Note also that the log shows two versions of Wire and two versions of SD being found on the system, one from the AVR core and one manually installed in the Libraries folder. That's not causing this particular failure, but mismatched versions between the two can cause weird behavior later.

jim-p · July 25, 2026, 11:22am

It uses the old Adafruit SD library. You need to install it.

GolamMostafa · July 25, 2026, 11:30am

It is always a confusion to me as:
Do we include the library in the sketch?

or

Do we install the library? If installing, then shouldn't it be installed in PC? But, a library is a file and NOT an application.

Deva_Rishi · July 25, 2026, 12:01pm

You include the library, but if it isn't present in any of the library folders, it should be 'installed' into one.

Installing is done through the library manager. Installing in this case is not much more than copying the files from a remote repository into the sketchbook libraries folder.

Many libraries that are used are included in a specific board (group) core and don't require 'installation' and since 'installing' a library is no more than a copying of files, it can also be done manually (If the library is not available in the library manager that is the way anyway)
How a choice for libraries is made is always a bit of a mystery

Multiple libraries were found for "Wire.h"
  Used: C:\Users\Norman\AppData\Local\Arduino15\packages\arduino\hardware\avr\1.8.8\libraries\Wire
  Not used: C:\Users\Norman\Documents\Arduino\Libraries\Wire

here a file from the AVR core is used.

Used: C:\Users\Norman\Documents\Arduino\Libraries\SD
  Not used: C:\Users\Norman\AppData\Local\Arduino15\libraries\SD

Here a file from the sketchbook folder is used (instead of a generic version)

There is also the option of copying the files required straight into the sketch folder, which will be the first choice for the compiler.
Any .cpp files found in the same folder as the included header file, will also be compiled.

In you case the confusion seems to stem from the use of the word 'install' and you are correct, nothing is really being installed, but installing is used for a lack of a better word i guess.

jim-p · July 25, 2026, 12:16pm

This is completely off topic and has nothing to do with solving @spiney problem.

DO NOT hijack posts for your own purposes.

jim-p · July 25, 2026, 12:17pm

@spiney please see post #5 for a solution.

J-M-L · July 25, 2026, 1:04pm

or post 4 if you want to use the "modern" SD library.

Deva_Rishi · July 25, 2026, 1:16pm

In this case does installing an older version requires the removal of the latest installed version ?

Personally i am not against seeking some extra clarification on that matter.

if @GolamMostafa is confused a little about that, it may also go for the OP.

pjrc · July 25, 2026, 1:48pm

How to tell which library actually gets used seem like related to the topic since the original issue is caused by differing versions of SD library.

When you have 2 or more libraries that both provide the same header file, like SD.h, Arduino IDE prints info about the conflicting libraries and tell you which one it actually used and the other(s) it ignored. If you select verbose compile output in File > Preferences (or Arduino IDE > Settings on MacOS), this info is always printed. Without verbose, it's only printed if an error prevents successful compile. You can either turn on verbose, or just add a simple syntax error and click Verify. The info gets printed to the console panel which is usually short, so you may need to resize the window or scroll up to see the libraries used info.

Hopefully that libraries used info can help you to know whether Arduino IDE used the library you intended. If it used one you didn't want, then you'll probably need to uninstall or delete or move the files so Arduino IDE doesn't see it.

Replying to an of topic post is also off topic. Please don't continue with off topic questions.

Thank you everyone for the replies. Firstly the unwanted semicolon was my fault and did not appear in the original working code; I saw that there was no semicolon and thought there should have been one - I was wrong gto say "unedited"
So I have downloaded the Github zipped code, but I don't know how and where to put it. Sadly it is so long ago that I did this project that I have forgotten what I suppose I once did. Is the problem that the old Adafruit library has automatically updated and I need to put the old one back in my library, leaving both there?

If you have issues, you can take it up with the moderator, which is a task you yourself are clearly not suitable for. If you enable your personal messages and/or are willing to communicate in a decent matter i am open to doing so. Please keep your authoritarian attitude focussed on things that you are more than qualified for, like actual solutions and part suggestions.

@Deva_Rishi and @jim-p
No more of this please

Put the zip folder anywhere you can later find it.
In the IDE click on Sketch->Include Library->Add ZIP Library. Then find your zip and select it

Thank you Jim-P. Done that. (and got rid of the semi colon.) I get what looks like the same fault message with Not used SD-Master as well as SD. In the library list is now both SD and SD-Master. Should I delete SD?

if you look closely, the compiler says :

spiney:

Multiple libraries were found for "SD.h"
  Used: C:\Users\Norman\Documents\Arduino\Libraries\SD
  Not used: C:\Users\Norman\AppData\Local\Arduino15\libraries\SD
  Not used: C:\Users\Norman\Documents\Arduino\Libraries\SD-master

so it's using the built in, default SD library. Try what I suggested in post 4...

if (!SD.begin(chipSelect)) error("Cd fail");

jim-p · July 25, 2026, 3:38pm

Try closing and opening the IDE or you can try what @J-M-L suggested.
