This project renders pre-built binary watchfaces on ESP32 using LVGL. A Kotlin script transforms the binary watchfaces into LVGL code, which is then compiled for the ZSWatch.

It was forked from esp32-lvgl-watchface.

Watchfaces demo

Watchfaces can be obtained from watch-face-wearfit or Chronos Dials. Since the ZSWatch uses a 240x240 screen, watchfaces of the same resolution are recommended.

• Install the Java JDK by running sudo apt-get install openjdk-11-jdk
• Install Kotlin by using sudo apt-get install kotlin
• Run export ZSWATCH_ROOT=<ZSWatch-Root> and replace ZSWatch-Root with the root directory of your ZSWatch project

• Run generate.sh and pass in the URL of the target watchface (i. e. https://github.com/fbiego/watch-face-wearfit/raw/main/dials/HW21/107_2_dial.bin)

generate.sh https://github.com/fbiego/watch-face-wearfit/raw/main/dials/HW21/107_2_dial.bin

• If the script is executed without an error you can compile the ZSWatch firmware
• Enjoy the new watchface
