This is my first post here on DBW Forum so have a bit of mercy.
The following refers to the DBW YouTube Video of June 5, 2022
I built and programmed the first experiment in the video. (Color Test) and it works just fine. So I wanted to proceed to the next Experiment (Animated Dial) I loaded the example, added the TJpg_decoder library as directed and tried to verify the sketch. No Dice. I got a fatal error (exit status 1). So I then switched to verbose and found that I need a library called "LittleFS.h"...However, I had installed that library previously with the only difference being that the library is called "LITTLEFS_master" note the capitalization difference.So I got into the src folder and found "esp_LittleFS.h" ;not the library the sketch was looking for. I also found "LITTLEFS.h" . This was confusing. So back to Github and I can't seem to find out anymore except that LittleFS has had an upgrade and its now "calling itself" LITTLEFS.h or that how I read it. Frankly it was confusing me. I am a lousy programmer. I'm more a hardware guy. And I need help.
So I joined the Forum here because Bill's videos have been incredibly helpful to me in the past and I hope his community is just like him.
Anyway TIA
David M

Rename the library directory to remove the master part.

I just did a bit more digging and LittleFS.h is built in, no GIT needed and in fact might mess you up. This library has undergone major change recently and is quite confusing to me at least.
I just did a compile with #include <LittleFS.h> and there was NO such file in my personal libraries folder and it compiled cleanly. Check the picture out. I intentionally blacked out the full path so you are not tempted to manually interfere. That is a system maintained path but as most users have an admin id you could mess it up.
What board are you working with, and did you install the board in the IDE?

Thanks for the response. I am using the ESP32-wroom-32D and it is installed in the IDE.I will give that a try and report back

@david-m You should delete those other LittleFS libs you downloaded, they may mess you up. I have 3 copies of LittleFS.h in my IDE platform libraries, one for esp32, one for esp8266 and one for rp2040. I will try my tiny test again with your board selected, the ESP32-wroom-32D

@david-m I don't see that board in the list, take a screen grab of the Tools drop down menu that shows the board selected.

Ron,
No its not in the list perse, however, it will work with "ESP32 Dev Module "on the board manager. And there is something to be said about being on the "right side of the grass" so many hard rollers from my day aren't. So I am glad I made it this far.

@david-m Ok. In that case you should re-install the IDE perhaps after deleting any library to do with LittleFS that you installed.

I was going through my installed libraries this morning and found that Arduino_esp32_master contains the "LittleFS.h" library that I think I need. However it is imbedded in the libraries
which are included in the master file. I think that the IDE is unable to find it as its in that enormous hierarchy. So do you have any ideas about where to put it. The ESP32 file can't be deleted as its used in many many places so I'm still confused about what to do.

@david-m I don't know where you got that arduino_esp32_master but it is NOT a library I have. It appears to be the IDF source code. You should not need that, it is the code needed to build the IDE etc. Equivalent to playing with sharp knives.
How/where did you install the arduino IDE? It should have been by going to the web site www.arduino.cc and select Software then download your platform (Win?) installer. Is that what you did, if so where/why do you have the open source for IDF?

@david-m Let me be very clear. Undo any installs you have done so far to do with the arduino and esp32. Start by installing from the approved location as I specified above. That will install the LittleFS.h in the correct place. If you installed anything else let me know what so I can guide you.

@david-m Set up your preferences to look similar to the enclosed pic, then add the following (copy/paste) to Additional Boards Manager. Let me know if you want the PICO boards as well.
