convert SPIFFS to LittleFS #26

Closed josef2600 closed 1 year ago

josef2600 commented 1 year ago

the SPIFFS has been out of support for a long time and has many problems. you can change it to LittleFS easily.

  1. replace all SPIFFS with LittleFS . and replace all #include <SPIFFS.h> to #include <LittleFS.h> .
  2. you can do the same for FFat too.
  3. the only change in code is freeBytes() . for this you can do this LittleFS.totalBytes() - LittleFS.usedBytes() . and that is that! the speed is 4 to 5 times faster to LittleFS . and it is resistance to many problems, included power lost and corruption of files. and probably to badsectors as well. and the amount of used ram is very low. specially compare to FAT, it is nothing! fat uses more than 45 KB more and when the page is open, it uses tow time the space in ram per file. in general it is better than fat, except in speed. it doesn't make a lot of different though! it is microcontroller anyway! LittleFS is included in the ESP Arduino boards and doesn't need any extra lib. it is updates with board manager.

and for partition scheme, use any SPIFFS partition for project, then use app for formatting and creating and uploading LittleFS partition to esp. the app link: https://github.com/lorol/arduino-esp32fs-plugin

That looks like a really good and easy enough improvement. Could you open a PR with only the fix to support LittleFS ?
