Building

Select your build environment in platformio. Default is emulator_64bits native.

When building for native check that you have configured SDL according to your platform. Follow the instructions here https://github.com/lvgl/lv_platformio?tab=readme-ov-file#install-sdl-drivers

The SDL path might be different depending on your configuration and you will need to update platformio.ini accordingly

Prebuilt Native

The prebuilt native applications have been included in the test folder, however you might still require SDL installed before running them.

Watchfaces

Check out esp32-lvgl-watchface project to see how watchfaces are converted from binary to LVGL code. You can add more watchfaces but you will be limited by the ESP32 flash size. In that case you can only compile your favorite watchfaces. Links to the pre-built binary watchfaces are included. Enable them in app_hal.h according to your build platform.

Chronos App

This is needed for additional functions on esp32 hardware as listed below.
