embedded-esp32

Summary: This repository contains a collection of Rust-based ESP32 embedded examples covering LEDs, servos, sensors, displays, WiFi, RFID, storage, and other common peripherals and features. Each example is organized in its own mXX_* directory and includes its own Cargo.toml, build.rs, and rust-toolchain.toml.

🚀 Overview

embedded-esp32 is a set of ESP32 embedded Rust example projects intended for learning and demonstration. It's suitable for developers who want to explore or prototype with Rust. Examples are concise and can be built and run independently.

🔧 Highlights

• Each example is placed in a separate directory (format mNN_name) and can be built and flashed independently ✅
• Wide coverage: LEDs, PWM/servos, buzzers, ultrasonic/IR sensors, OLED/TFT/EPaper displays, WiFi (STA/AP/Web), BLE, RFID, SD card, etc. 🔌
• Each example contains necessary toolchain configuration (rust-toolchain.toml) for reproducibility and easy switching 🔁

📁 Structure

The root directory contains multiple example folders, for example:

• m1_led_in, m2_fading_led_in, m3_fading_led_out: LED demos
• m10_servo_motor, m11_servo_motor_mcpwm: servo / PWM
• m13_wifi_sta, m15_wifi_web, m18_wifi_ap: WiFi client/server/web demos
• m22_oled_text, m23_oled_sig_image, m24_oled_mul_image: OLED displays
• m28_rfid_uid, m29_rfid_read_data: RFID operations
• Others: sensors (temperature, LDR, ultrasonic), displays, SD card, E-Paper, BLE, etc.

Note: Each subdirectory usually contains more detailed example instructions and build/flash steps. Please read the subdirectory README or comments first.

⚙️ Quick start

1. Install Rust and required tools: rustup, cargo, and make sure you can use or switch to the toolchain specified by the example directory (rust-toolchain.toml).
2. Enter an example directory:

   cd m15_wifi_web

3. Read that example's instructions and install external tools as needed (e.g., cargo-espflash, esptool.py, probe-run).
4. Build:

   cargo build --release

   cargo run --release
