Embedded Cli

Single-header CLI with history and autocompletion for embedded systems (like Arduino or STM32)

Internet of Things (IoT)CMIT

Abstract

Embedded Cli is an open-source Internet of Things (IoT) project. Single-header CLI with history and autocompletion for embedded systems (like Arduino or STM32). Single-header CLI library intended for use in embedded systems (like STM32 or Arduino). It is built using C, Arduino. Key capabilities include: Dynamic or static allocation; Configurable memory usage; Command-to-function binding with arguments support. The complete source code is publicly available on GitHub under the MIT License, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

Single-header CLI library intended for use in embedded systems (like STM32 or Arduino).

2. Objective

Single-header CLI with history and autocompletion for embedded systems (like Arduino or STM32)

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

3. Key Features / Modules

  • Dynamic or static allocation
  • Configurable memory usage
  • Command-to-function binding with arguments support
  • Live autocompletion (see demo above, can be disabled)
  • Tab (jump to end of current autocompletion) and backspace (remove char) support
  • History support (navigate with up and down keypress)
  • Limited cursor support (navigate inside input with left and right keypress)
  • Any byte-stream interface is supported (for example, UART)
  • Single-header distribution

4. Technology Stack

CArduino

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/funbiscuit/embedded-cli.git
cd embedded-cli

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?
