I now use LVGL 7.4, using the MCU is NXP MXRT1011, now use the UI images, fonts, and stored in the flash program, download the program is very big, every time takes time, and now want to separate the program, UI and font download to flash the designated area respectively, and then you just need to download the program, would you please tell me why I should turn images and font format, using what tools transformation, how to access these images and fonts
You need to setup the FileSystem interface
As for the file types, LVGL already supports multiple image decoders
With fonts you can use TTF or bin
I’d recommend you try LVGL Pro Editor, this converts the fonts & images into the chosen format
