ESP8266/ESP32 FreeRTOS projects

Internet of Things (IoT)CApache-2.0

Abstract

Esp is an open-source Internet of Things (IoT) project. ESP8266/ESP32 FreeRTOS projects. It is built using C, ESP32. Key capabilities include: Single codebase for ESP8266 and ESP32 support; Simple two-button + four-led physical interface for configuration reset and basic diagnostics/tests; USB Console CLI and HTTP Web UI for configuration and advanced diagnostics (WiP). The complete source code is publicly available on GitHub under the Apache License 2.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

ESP8266/ESP32 FreeRTOS projects

2. Objective

ESP8266/ESP32 FreeRTOS projects

This project demonstrates how C, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

3. Key Features / Modules

  • Single codebase for ESP8266 and ESP32 support
  • Simple two-button + four-led physical interface for configuration reset and basic diagnostics/tests
  • USB Console CLI and HTTP Web UI for configuration and advanced diagnostics (WiP)
  • Fully configurable via the USB Console CLI or HTTP Web UI
  • WiFi STA/AP support with DHCP or static addressing
  • Ethernet support with DHCP client/server or static addressing
  • Support for WS2811/WS2812B, SK6812 RGBW, SK9822 and APA102/P9813 LED protocols
  • Up to four separate SPI, UART or I2S outputs with different protocols
  • GPIO output-enable multiplexing for multiple outputs with a single output peripheral
  • I2C GPIO expander (PCA9534/9554) support for status LEDs, DMX/LED output enables

4. Technology Stack

CESP32

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C compiler (gcc)
  • Target board where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/qmsk/esp.git
cd esp

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?

9. Source Code & License
