🎮 Ready to add Nordic nRF52840 to your multi-platform Rust arsenal? This tutorial walks you through setting up and running Embassy applications on the powerful Nordic nRF52840 Bluetooth-capable microcontroller!

Following up on my task-watchdog video, I’m expanding our portable embedded Rust journey to include Nordic devices. This step-by-step guide shows you exactly how to configure, build, and run Rust Embassy applications on the nRF52840 from complete scratch.

This video covers:

  • 🔷 Introduction to the Nordic nRF52840 capabilities and features
  • 🛠️ Setting up the complete development environment for nRF52840
  • 📄 Creating and understanding all required config files (main.rs, Cargo.toml, .cargo/config.toml, build.rs, memory.x)
  • 💡 Building a basic LED blink example with Embassy
  • 🐺 Extending the task-watchdog library to support nRF devices
  • 🧩 Adapting portable code patterns to work across all platforms (Pico, STM32, ESP32, and now nRF)

I start with absolute basics so you can follow along even if you’ve never touched a Nordic device or Embassy before, and progress to integrating our task-watchdog examples from the previous video, demonstrating true cross-platform portability.

Whether you’re interested in Bluetooth applications, ultra-low power devices, or just expanding your embedded Rust skills to another platform, this tutorial start you on the journey of building robust applications on the nRF52840.
