Animated_dial Compliation error - ESP32 / ILI9341

[Amitabh-wq]

Hi, I am trying to test the example called 'Animated_dial' but geting the IDE error:

I:\Users\UserJ\Documents\Arduino\libraries\TJpg_Decoder\src/TJpg_Decoder.h:23:26: fatal error: LittleFS.h: No such file or directory

I have installed all the libraries required. Any toughts? Thanks

Not all processor board packages provide LittleFS. Those that do include:
ESP32
ESP8266
RP2040 (Earle Philhowers package only)

Consult the board package documentation.

I am using the ESP32:

[code]
TFT_eSPI ver = 2.4.51
Processor = ESP32
Frequency = 240MHz
Transactions = Yes
Interface = SPI
Display driver = 9341
Display width = 240
Display height = 320

MOSI = GPIO 23
MISO = GPIO 19
SCK = GPIO 18
TFT_CS = GPIO 15
TFT_DC = GPIO 2
TFT_RST = GPIO 4
TOUCH_CS = GPIO 5

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 40.00
Touch SPI frequency = 2.50

Load the latest master jpeg library and try that.

Hi Bodmer, I am using the TJpg_Decoder latest version 1.0.3 but it has the above compilation error.

[Bodmer]

Which version of the ESP32 board package are you using?

[Bodmer]

I checked with board package 2.0.2 (latest) and it runs fine and LittleFS.h is found.

I suspect you are using an old 1.0.x board package as those version did not provide LittleFS support.

[Amitabh-wq]

I did the following, I edited the header 'TJpg_Decoder.h' (from the TJpg_Decoder library) I renamed the call of library from <LittleFS.h> to <LITTLEFS.h>, as the LITTLEFS library is in capital letters. I use ESP32 boards V 1.0.6 which is the most stable for my projects. The compilation went without errors, but the graph has problems, the pointer is erasing the numbers, see the photo below:

In addition, before I also tested ESP Boards V 2.0.2 and this same error occurred.

[Bodmer]

The display SDO line must be connected. Have you specified the read frequency in the setup file?
#define SPI_READ_FREQUENCY 10000000

[Amitabh-wq]

Hi Bodmer, I followed your instructions and it worked. Only the numbers in the center are overlapping, I don't know if this is normal. See below

[Bodmer]

The numbers problem has been fixed in the latest master library on Github.

[Amitabh-wq]

I am using the latest.

[Bodmer]

Latest is 2.4.61 and is only available from Github here a the moment:

I have installed it manually and replaced with my configurated files. Now it is working fine. Thank you.

[Bodmer]

Great, I will be releasing the new version soon.

I'm curious, where are you getting 2.0.2 package from? I came here with the same "LIttleFS" not found problem. I saw @Amitabh-wq comment to use uppercase LITTLEFS and that has worked for me. As far as I know I have the correct board url > https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json and there's no 2.x.x version?

[Bodmer]

Currently I am using the development branch link:
