Xiao Prism Buddy

This project is built on the ESP32 IoT Development Framework (IDF) and utilizes the C++ programming language for development.

This project demonstrates the use of a splitter prism to create a three-dimensional display. Configuration is provided for connecting with a local home assistant install for fetching weather data for display on the device via animations.

Function

• Time and animated weather display
• Activity timers and presence detection for sleep behavior (hiding text)
• Gesture sensor based control scheme
• Animated gif browser
• Cryptocurrency watcher

• esp-idf: v5.0.4
• LovyanGFX: v1.1.9
• LVGL: v8.3.11

Preparing your environment

1. Install esp-idf 5.0.4
2. Export your environment for esp-idf
3. Build, flash, and (optionally) monitor the deployment
