How to use SPIFFS with lv_arduino on ESP32?

[Skorpi08]

Have anyone an example to use SPIFFS with lvlg?
How can i use pictures from SPIFFS?

I think @TridentTD may have implemented this.

[Request] lvgl's filesystem for ESP32's SPIFFS?

Description I would like to use a binary image-source that placed on ESP32’s SPIFFS. However lvgl needs to create lvgl’s filesystem first. I have read from the manual, but I don’t know about file and filesystem much to link between ESP32’ SPIFFS to lvgl’s filesystem by drive-letter F: . Wish lvgl has the code for SPIFFS’s filesystem too. Thank you very much.

Sorry, I can’t do anything with that.

Have you tried something already? I’m using the esp32 micro but haven’t used SPIFFS with it, there are lots of arduino examples online, some of them:

• https://forum.arduino.cc/index.php?topic=533488.0
• https://www.reddit.com/r/esp32/comments/blerv8/why_can_i_not_add_png_files_to_my_spiffs_data/

I have tried this: https://github.com/Bodmer/TJpg_Decoder
and this: https://github.com/Bodmer/TFT_eSPI/tree/master/examples/Generic/TFT_SPIFFS_BMP

but i need an drv for lvgl to use it for Buttons or Background.

If you’re familiar with the SPIFFS API it shouldn’t be too difficult to put together a driver based on this template. If all you’re looking to do is read images, you only need a few of the callbacks implemented.
