There does seem to be an issue with SPIFFS slowing down appending onto large files and ultimately failing. So maybe the thing to do is to have a series of files each capable of holding say 256 records. Indexing would still be pretty straightforward as the high byte of the index would select the fil...

Re: SPIFFS fast enough for a one second data logger?

Hi ESP_Angus and ESP_igrr. Sorry to resurrect this thread, if possible could a simple example be shared of the correct way to initialize and do serial write to the internal flash device using the library.

Re: sppiffs using up a lot of space

Why not use 1 file for all the records to maximise space efficiency? Decide on your maximum record size. Block in file is Length (4 bytes) + max size. Seek to record position (n x (4 + max Size) Read or write length + data Will try this method as well. Tried to put sixty records in a file and it wo...
