I am looking for an example of how you can log data in spiffs and then access/display this data in the ESP32 webserver, does anyone have some examples lying around?
We have an example like that in the Build Web Server eBook.
The example is a bit complex, but it logs data into a file in SPIFFS and then, loads the results in the web server.
The project is “Web Server: Display Sensor Readings from File (Charts)”.
Let me know if this helps.
