File_ESP32_SDMode problem: file close is not working

[stefan.erni]

Hi Ben

File_ESP32_SDMode is a fantastic component!
Very quick and easy to understand.
So fast that you can even use it to create csv file with a sample rate of a few Hz!
easy to open the file with excel later.

but there is a limitation with the number of file.

if I choose 4 then I can create 3 files, then my programme crashes
if I choose 5 then i can create 4 files, then crashed my programme.
I cannot set more than 5 files count.

I always try to close the files but unfortunately that doesn't work.
(on the file sd-card there was not a problem)

Stefan

Hi Ben

There is a problem with file close in the ile_ESP32_SDMode component.
I just want to create a file, open it, append data and close it again.
Then create a new file and do the same again.
But somehow it doesn't work.
As if the number of files opened at the same time is increased and more than 4 files are written to the sd-cards,
the programm crashes an reset.

regards

Stefan

Hi Ben

Is there a command to close the file with a c code where I can test?
Just 4 file are not enough to save on the sd-card

also a small problem:
I use the same macro with the "old" esp32 sd-card component to check what name becomes the next recordet file.
i open with a list of which files are already on the card.
If a file is available, I close the file and try to open the next one. Until I can't open a file, I have the next number for the filename.

look for the file on sd-card:

Hi Stefan,

I've not used that component, but have you tried limiting the file count to 4 and using a second component for files 5-8? It probably won't work and is not ideal, but is a quick thing to check.

Hi Steve

You've given me an idea... Thank you very much.
Yes but I don't need a second componet, but before each recording I un-initialisee the component and initialise the same again. That works !!!
