HI,
I have the BC24 Weather RGBW. I have this connected to my WiFi.
I have trying to compile the SDL__ESP32_BC24_WEATHER program using Arduino IDE but get an error message relating to
# include <TimeLib.h>
SEEBELOW

I note there is a

I f I exclude <TimeLib> from the program I get additional error messages relating to minutes, seconds etc. See below

Error compiling for board Adafruit ESP32 Feather.

-------
I have followed the set up instructions for the Arduino (although I am a novice with the IDE) and am using the Adafruit ESP feather ( see above)

I would be grateful for any advice.

Thanks

I have just looked at READ.md in the SDL_ESP32_BC24_WEATHER directory. I can't find any reference to TimeLib.h.
I note, as stated above that there is a file TimeLib.h in the directory.
is this the same file that is not properley installed or I am missing a library file with the same name?
I have followed the set up instructions for the Arduino IDE from the Tutorial (although I am a novice with the IDE) and am using the Adafruit ESP feather.
Sorry, but I need a little more of steer as what I have got wrong.

That should do it. BP

Thanks
Cleared the <TimeLib.h> problem but have a problem with 'undefined references" in what appear to link files in a temp folder. I can't see how to define date/time in the sketches.
How do I resolve this?

Do you have timelib.h in your program directory? And does your SDL_ESP32_BC24_Weather.ino file contain: #include "TimeLib.h" BP
