LittleFS

[MichaelPNolan]

So far I can't get a single file or directory read - i bought a new card. I formatted it many ways I used this
https://github.com/bluscape/LittleFS-Explorer-for-Windows
tool to format it after a while of figuring out I was getting nowhere.

So - what is going on, is this project going to us the SD card or partitioned memory?
Now that I'm looking at this https://www.youtube.com/watch?v=4r6YZlLfKfw - i have a bit more clue what seems to be going on. Never really thought much about this data directory or this partitioning until today.

Regards
Michael

This is where I am - I can upload the files with the tools. The files aren't opening though ... do I need a different library I wonder.

The error occurs in case the following line fails:
File f = LittleFS.open(samplePlayer[i].filename);

You should try the LittleFS example. I am not sure if something else is broken. I started testing and using ESP32 arduino board version 2.0.2. I pushed some changes into the repo some days ago

I am surprised that you are talking about a SD card. LittleFS is used on the ESP32 memory. The executed code and some additional data are stored on flash and separated in two parts. That's why the upload tool is required. The drum computer does not use the SD card (yet).

[MichaelPNolan]

Yes, I came to this realization, having no experience with storing data in the LittleFS. Now, however, i still can't get files to read in so that is still a problem I have to find. Getting the tools installed to write the partition to memory - i got through that. Yes, I was fully lost assuming you used an SD card for samples. My drum samples will take a lot of memory - i have to figure out the right bitrate to make it realistic. Regards Michael

The error is generated by
File f = LittleFS.open(samplePlayer[i].filename); in line 200 in sampler.ino.
It might require some further analysis to figure out what went wrong here.

[marcel-licence]

I've updated the project. It seems that the '/' was missing in front of the filename. The open function was not able to find the requested file without selecting a path.

[MichaelPNolan]

Ok - cool, i'd like to give it another try! Thanks
