→File-system, Writing and data lost
So, even if LittleFS do have some minimal buffering, it is possible to force writing to the flah ( with {{fname|flush()}} ). So the user code can rely on better file-system stability and better control over forced writing operation.
So, even if LittleFS do have some minimal buffering, it is possible to force writing to the flah ( with {{fname|flush()}} ). So the user code can rely on better file-system stability and better control over forced writing operation.
The following example just {{fname|flush()}} writes at every line written to the file.
Power can be lost at every moment, the flushed writes are safely stored.

{{underline|Please note:}} abusing the {{fname|flush()}} operation will slow down the code and will degrade flash faster (Flash Memory cells do have a maximum write cycles).
