ESP32 Data Logging Temperature to MicroSD Card

Hi !

You make great projects, thank You. Wish I had more time….. The project in the title made me wonder where does the SD library keep the data read from a .txt file on SD card? Is there a size limit for how big file it can open?

Thanks, Janne Numminen

Hi Janne.

I’m sorry, but I’m not really sure if I understood your first question. Do you want to know how you can read the data from the txt file and save it on a variable for example?

As per the file size, I don’t know if there is a limit.

I’m sorry that I can’t help much.

Maybe if you try to reformulate your first question, I can help you better.

Regards,

Sara
