This is only a report of how much memory your sketch uses. It is normal and expected and doesn't indicate any problem.

Don't be alarmed by the red color of the text. Even though it is not an error message, the ESP8266 boards platform developers decided to print the report on the "standard error" stream (AKA "stderr") instead of the "standard output" stream (AKA "stdout"). Because the stderr stream is typically used only for warnings and errors, Arduino IDE colors text received from this stream in red.

So it looks like all is well now and you can get back to working on your project. If you are experiencing some behavior that doesn't match you expectations, we can help with that; just provide a detailed description.

I merged your posts on the same subject that you made on the other topic @agitha.

In the future, please use a single topic for your posts on a given subject matter. Posting about the same thing on multiple topics is considered "cross-posting".

Cross-posting is against the Arduino forum rules. The reason is that duplicate posts can waste the time of the people trying to help. Someone might spend a lot of time investigating and writing a detailed answer on one topic, without knowing that someone else already did the same in the other topic.

Repeated cross-posting can result in a suspension from the forum.

This is basic forum etiquette, as explained in the "How to get the best out of this forum" guide. It contains a lot of other useful information. Please read it.

Thanks in advance for your cooperation.

Where can I find the C++ code to the thing you are describing?

ptillisch · July 4, 2023, 4:18pm

Hi @sircartier. I'm not sure what you mean by "thing you are describing". Please provide a more detailed explanation of what thing exactly you want the C++ code for and I'll try to help you.
