<![CDATA[Cannot compile M5Paper Weather sketch]]>I have downloaded this sketch along with all of the XX.h files and installed them in my Arduino directory, as I have prviously done with other GIT sketches. https://github.com/Bastelschlumpf/M5PaperWeather/tree/master/weather Unfortunately I cannot get this sketch to compile, it complains that in "..../Time.h MyData was not declared in this scope"

I have noticed that in Time.h there is the line 22 "#pragma once" which is not followed by any local XX.h files as it is in the other local libraries and .h files. I am nor familiar with" #pragma once" and am wondering if another library is supposed to declare MyData. MyData is declared as a class in Data.h.

I managed to find a few libraries that needed to be installed. I'm still having trouble with DynamicJsonDocument doc(35 * 1024); in the Weather.h file. It seems the DynamicJsonDocument was deprecated, and I haven't found a good work around.
I very much, appreciate the assistance, and I hope to stumble accross the solution soon.
I'm working with Arduino 1.8.19, and I'm thinking this code would compile for me if I knew what version the original author was using. I am not able to DM the original author on GitHub. I'll keep trying, and post updates as I find solutions.
Thank you.

@Steve1
Hi,

It seems there might be some missing libraries to install. I just don't know which ones yet...

Arduino should tell you during compile Whicker ones are missing

looks like that issue isn't new. See here.

Maybe try to contact the owner of the code?

Thanks
Felix
