Update:
I solved some of my problems:

changed all baud rates to 74880 removed the gibberish
the WEMOS is printing
” ets Jan 8 2013,rst cause:2, boot mode:(3,7)

load 0x4010f000, len 3424, room 16

” when it boots up. if anyone can explain I would be greatful.

The uploaded file names did not have digits on the end just and extra “.txt”

File file = LittleFS.open(“test_example.txt.txt”, “r”);
is the line of code I had to use to read the file as per your code presented in this tutorial.

Thanks

would not read the files. “Failed to open file for reading” was all I got.

I am using windows, Arduino IDE 1.8.19
Wemos D1 R2 [not a mini]

After much head banging I have proved most of it works … NOT as expected:
The upload seems to be adding suffixes to the file names.
but now I have proved the text in the files is uploaded correctly.

I have checked my files in ‘data’ file names are:
“test_example.txt”
“file1”

Essentially I am using the program file supplied above, I have added some prints and some extra code at the end to try and understand what is going wrong. OUTPUT TO SERIAL IS :
<
“lots of unprintable and extended char which wont copy & paste which is not exact the same every time then I get”
LitFS_test on Wemos Serial.begin@115200 Aug24 <- my line of print
after Serial.begin()
Failed to open file for reading 1
Failed to open file for reading 2
File Content:
===================== <– my print sttmnt
file1.txt44
file 1
a test file in text format
Aug 2024
test_example.txt.txt55
This is testing text
in littleFS_test.txt

I dun it.

I dont understand the unprintables, its like wrong baud rate, but that doesnt make sense because prints everything else fine. It does seem to occur before serial.begin().
Most of it is the text in my text files and is correct.
The file names ??? as you may see :
“file1” has become “file1.txt44”
“test_example.txt” has become “test_example.txt.txt55”

Sorry I have not done a good job of formatting the output, I assure you, my problem is the filename is changed between the data folder and the littleFS

Thank you for any further assistance / guidance

What errors did you get?
You just need to replace the word “SPIFFS” with “LittleFS”
Make sure you have your libraries updated as well as the ESP8266 boards in Tools > Boards > Boards Manager.

Yeah. Best news lately.

After googling, it looks like LittleFS should be used.. Tried replacing SPIFFS with LittleFS in code but loads more errors.
Any suggestions?
Thanks

Hi.
Check this tutorial: https://randomnerdtutorials.com/esp8266-web-server-spiffs-nodemcu/
In the code, instead of “SPIFFS” use “LittleFS”.
This example shows how to display the files saved on LittleFS on a web page that you access when you go to your board IP address..

Instead of opening a file, I want to open a html very simple default web page that I have uploaded
file = LittleFS.open(“/test_example.txt”, “r”);

so I need my file to read like this File file = LittleFS.open(“/menu.html”, “r”);
but of course, that displays the contents of my HTML file. Instead, I need my local browser to open it.

Is there an easy way to do this, so if someone goes to the local ip address of my microprocessor, I can put a default web page/ menu instead of just some text ?

I am using a NodeMCU (4mb Flash) with IDE v2+ and I can successfully get the text file to upload and be displayed!

Many thanks for your time and your great site!

I tried to use it for TFT_eSPI_OpenWeather_LittleFS which puts all the icons, fonts, etc. into folders. Upon checking, all the folders were empty. Apparently it only copies root level items. I made a sketch that copies all files and folders from an SD card to the LittleFS file system. It can be found here:
https://www.mulvey.us/Copy_SD_to_LittleFS.zip
You need to partition the file system the same way you will use it in the final sketch.
It also does a touchCalibrate and saves the calibration file. You can REM out that command if you don’t need it.

I have tested it and works good.
Thanks to you

Hi.
That’s great!
Thanks for letting me know. I’ll test it and create a tutorial about it ASAP.
