A WiFi-connected Pokémon-themed clock powered by an ESP32 microcontroller and an MIPI DSI LCD display. This project gives new life to a nostalgic children's Pokémon clock by replacing its original electronics with modern, programmable hardware. It features animated Pokémon graphics, time synchronization with NTP, and is fully customizable.

This project transforms a toy Pokémon alarm clock into a modern IoT device using an ESP32-C6 and a MIPI DSI LCD screen. It's a fun and hackable hardware/software project that combines nostalgia with embedded graphics, powered by the slint-ui graphics library.

• 💡 Animated Pokémon clock face
• 🦀🐚 nostd ! True rust experience
• 🖥️ Desktop simulator, to speedup development
• 🖼️ Display via ST7789 compatible display (through mipidsi project)
• 🌐 WiFi connectivity
• 🕒 NTP time synchronization & Realtime clock DS3231
• 🔧 Easily customizable and open-source
• ⚡️ Embassy framework
• 🎮 Hackable

• An ESP32-C6 microcontroller, but every ESP32 microcontroller should work, after adaptations
• A 240x240 Round LCD display (GC9A01)
• A realtime clock module (here a DS3231, but a DS1307 works flawlessly with the right lib)
• A Repurposed Pokémon clock frame (optional)

• Rust 1.85
• Follow instructions of Rust on ESP book, RISC-V, nostd
• Slint-UI 1.12

1. Clone the Repository

git clone https://github.com/mgrenonville/esp32-mipidsi-clock.git
cd esp32-mipidsi-clock

2. Build & run the simulator

cargo run --bin ui_simulator --no-default-features --features=simulator --target x86_64-unknown-linux-gnu

See src/bin/ui_simulator.rs for the key bindings

Using and following table, wire the board.

Create a file .env based on .env.template with your timezone, SSID and WIFI passord, plug the board and execute:

cargo espflash flash --release --monitor

• Huge thanks to Warren Clark / Woostar Pixels (Portfolio) for allowing me to use his artwork
• Kudos to Embassy, expressif, rust, and slint-ui project, for these amazing tools
