- Sat Aug 22, 2020 5:27 am #88421 Does anyone have any tips or tutorial links on the process of porting SPIFFS code to LittleFS?

I did the benchmark tests and am very excited to see how my code runs on the new file system, but it is not a drop-in replacement (I tried) so any help would be appreciated, if anyone else has had experience doing this?

I am using SPIFFS to read a CSV text file, reading in Strings and converting to int - come to think of it, there should be a better way for me to read in some bytes from a file system... Old code it works though

- Sat Aug 22, 2020 6:21 pm #88429 Very simple, just did it...

//#include "SPIFFS.h"
#include <LITTLEFS.h>
#define SPIFFS LITTLEFS

All instances of SPIFFS.read() SPIFFS.write() SPIFFS.close() SPIFFS.open()
are now
LITTLEFS.read() LITTLEFS.write() LITTLEFS.close() LITTLEFS.open() are now

Its the same usage... they were smart doing this!

- Sun Aug 23, 2020 12:49 am #88431 Thanks Richard that is the smart way to do it for sure. After posting the question I did change all the "SPIFFS" in my code to "LittleFS" manually, not expecting it to work, but it did!

Your way is much more elegant, I will be doing that for the rest of my programs that use SPIFFS going f forward, thanks
