- loading JPEG files from STM32 internal storage memory
- loading JPEG files from SD card via SdFat library
- The library requires about 3KB of RAM (can be shared for other applications)
- examples for ST7789 and ST7735
- slideshow examples: 25 images in 160x128 pixel resolution or 12 images in 240x240 pixel resolution stored in internal STM32 128KB!
- images can be rendered at given X,Y so it could be used for high quality user interface
- big images can be scaled down 1:2 to 1:8 and rendered directly on the LCD
- decoding and rendering 160x128 pixel JPEG takes about 80-100 ms, and 240x240 - about 220 ms
