Reading and writing text files on SD cards with ESP32


This is a sample of reading and writing a text file saved in an SD card with ESP32.
I couldn't find much simple sample code on the net to read and write, so I drew it.

I used this site as a reference for wiring between the SD card and ESP.

And I used this code as a reference.
