FIX fatal error: littlefs.h: no such file or directory

Hi, guys! I hope you will be doing fine. In this article, we’ll talk about the fatal error: littlefs.h: no such file or directory, and the best possible solution to fix it.

This error may occur when trying to build an Arduino sketch using LittleFS, the LittleFS File System on the Arduino board.

LittleFS File System is a flash-friendly system designed for embedded systems. For instance, it was developed to work on devices with only a limited amount of RAM and storage for microcontrollers.

If you attempt to build an application that utilizes LittleFS as the LittleFS files system, you might encounter the following error message:

Fatal error: littlefs.h: no such file or directory 

A variety of factors could cause this error:

• The Little Library isn’t installed.
• This little Library does not come as part of your sketch.
• The Little Library isn’t compatible with your device.

How to Fix fatal error: littlefs.h: no such file or directory

To fix this issue, you must do these things:

• Download LittleFS library.
• Incorporate the LittleFS Library into your Sketch.
• Check to see if you’ve got the LittleFS Library is compatible with your board.
• Set up LittleFS library.
• The first thing you have to install is LittleFS.
• The Library can be installed by using the Arduino Library Manager.
• Open the Arduino IDE and Sketch> Include Library> Manage Libraries.
• Within the box for searching, enter “littlefs” and press Enter.
• You’ll find the LittleFS Library listed in the results list.
• Open the Library, then click on the Install button.
• Once the Library is installed, you’ll be able to use it in your drawings.
• Add the LittleFS Library into your Sketch.
• After you have installed the LittleFS Library, you’ll need to incorporate it into your Sketch.

It is possible to do this using Sketch, Include Library, and LittleFS.

It will include the following code line in your design:

#include

Check to see if the LittleFS Library is compatible with your board.

LittleFS library can be used with various Arduino boards, including Arduino Mega, Arduino UNO, Arduino Mega, and Arduino Nano.

It is, however, not compatible with all Arduino boards.

You might encounter a fatal error when running a motherboard not identified as compatible with your system. h there is no directory or file error.

To resolve this issue, you’ll need a compatible motherboard.

Here is the complete list of boards compatible with this:

If you’re using an incompatible board, you could use a compatible one instead.
