lvgl-widgets-demo

Wraps the upstream lv_demo_widgets() — LVGL's headline showcase of every standard widget (buttons, sliders, tabs, charts, meters, lists, animations).

Source: examples/lvgl-widgets-demo/.

What it shows

• LVGL renders into the Zephyr display subsystem unchanged.
• The SDK's st7789 chip driver handles the panel-specific init.
• Customer code stays board-portable — no vendor-specific symbols, only <alp/*> peripheral surfaces + the portable LVGL API.

Hardware needed

• An E1M-AEN-family SoM (E7 recommended for the SRAM headroom).
• E1M-EVK board (or any board exposing SPI0 + two GPIOs).
• 240×320 ST7789 TFT panel wired to SPI0 + reset/DC GPIOs.
