Wemos D1 mini upload failure

Using Arduino Programming Questions
1

having trouble placing code onto my wemos board. fresh install of audrino ide, correct drivers for the board, com port recognizing the board. no luck. brand new to audrino so i am likely doing something wrong. here is the error code.

Arduino: 1.8.16 (Windows Store 1.8.51.0) (Windows 10), Board: "LOLIN(WEMOS) D1 R2 & mini, 80 MHz, Flash, Disabled (new aborts on oom), Disabled, All SSL ciphers (most compatible), 32KB cache + 32KB IRAM (balanced), Use pgm_read macros for IRAM/PROGMEM, 4MB (FS:2MB OTA:~1019KB), v2 Lower Memory, Disabled, None, Only Sketch, 921600"

fix this

useless-box.ino:38: undefined reference to `_ZN10SpeedServo6attachEh'

it says that in useless-box.ino, line 38, you are using _ZN10SpeedServo6attachEh and the compiler has no clue what this is.

Do yourself a favour and please read How to get the best out of this forum if not done yet.

It's not an upload failure, it is a compile error.
Post your code and the errors in code tags as referenced in the link by J-M-L. The forum software messes up the formatting if you don't use code tags.

Please post a link to where you downloaded this "useless-box" sketch from. That will give us the information we need to provide you with detailed instructions for fixing this error.

Hello,
i've the same (similar) problem.
link to GITHUB repository
should i install any additional libraries ?

Hi @kapi_25. Please follow these instructions:

  1. Download the full sketch from this link:
    https://github.com/balassy/useless-box/archive/refs/heads/master.zip
  2. Unzip the downloaded file useless-box-master.zip
  3. Rename the unzipped folder from useless-box-master to useless-box
  4. Start the Arduino IDE if it is not already running.
  5. Select File > Open from the Arduino IDE menus.
  6. Select the file useless-box.ino from the useless-box folder.
  7. Click the Open button.

There are two tricky things about this "useless-box" project:

Multi-file sketch

This sketch has multiple files. Since many Arduino sketches only consist of a single .ino file, it is easy to think they are all that way. But it is actually the folder that is the sketch, and that folder can contain multiple source files that are compiled into a program. You will see each sketch file as a tab in the Arduino IDE.

So someone who has only ever seen single file sketches might think that they can grab only that useless-box.ino fle from the GitHub website and be done with it, but really you need all the files.

The solution is to download the entire contents of the repository from that link I provided.

Sketch name mismatch

The way the author of the sketch structured it causes the downloaded folder name to be useless-box-master, while the primary sketch file name is useless-box.ino.

That is not allowed. The folder and file name must match. When they don't, the Arduino IDE offers to move the file to an appropriately named folder. It seems very helpful, except that it only moves the single file you opened. That is disastrous with a multi-file sketch like this one.

The solution is to rename the folder so that it matches perfectly with the primary sketch file name.

Thats work. Thank you.

You are welcome. I'm glad it is working now. Enjoy!
