Project Overview

Full-Stack-Embedded-System is not a single integrated product. It is a compact embedded systems repository that combines two project paths: W5500 Ethernet examples for ESP32-based MCUs and an automatic irrigation system implemented as a submodule.

The Ethernet_W5500 path explores how to connect MCUs with the W5500 Ethernet module for embedded systems and IoT applications. Its README lists ESP32 + W5500 examples for Arduino and ESP-IDF as completed, with STM32 + W5500 marked as planned.

The Automatic_Irrigation_System path is a 2022 automatic irrigation project developed for a national startup competition. Its README describes local keypad control, timer-based scheduling, remote mobile operation, and testing on the EIU campus before selection among the top 70 teams in the national finals.

The two project paths share an embedded IoT theme, but the repository does not show them as one merged W5500-based irrigation gateway.

WIZnet Product Role

The WIZnet product used in this repository is the W5500 Ethernet module. It is used as an SPI-based Ethernet controller for ESP32 networking examples. The Arduino example defines W5500 reset, chip select, SCLK, MISO, and MOSI pins, initializes SPI, starts Ethernet, and opens a TCP server on port 5000.

The ESP-IDF implementation uses W5500 MAC/PHY creation, SPI bus setup, esp_netif, static IP configuration, and lwIP socket APIs. The TCP server is implemented through socket, bind, listen, accept, recv, and send.

Operation Flow

W5500 Ethernet Flow

1. ESP32-S3 configures W5500-related GPIO and SPI pins.
2. Ethernet initialization is performed through Arduino Ethernet library or ESP-IDF Ethernet driver.
3. The board obtains or sets an IP address.
4. A TCP server listens on port 5000.
5. A PC-side client connects and exchanges TCP data.
6. The Python client validates the echo server behavior from the host side. 

Automatic Irrigation Flow

1. The STM8 controller manages local control components such as keypad, LCD, RTC, watchdog, and valve outputs.
2. The ESP32 gateway connects to Wi-Fi and communicates with backend PHP endpoints over HTTP.
3. Control data is received from the backend and transferred to the STM controller over UART.
4. Sensor and valve-state data are sent back to the backend.
5. The mobile application layer exists as a Flutter project scaffold with IoT-related dependencies. 

Technical Characteristics

Strengths

Limitations

Application Value

This repository is useful as an embedded IoT prototype study case. It provides W5500 Ethernet bring-up examples, TCP server validation, ESP32 gateway logic, STM8-based local control, and backend/mobile integration elements in one project collection.

The strongest technical value is the combination of low-level device connectivity and higher-level IoT system layering. The repository shows how embedded networking, local control, backend communication, and app scaffolding can be arranged in a prototype-stage system.

Author Information

The GitHub repository owner is NhatTran-97, and the automatic irrigation project is linked as a submodule from the main repository.

Final Summary

Full-Stack-Embedded-System combines ESP32-S3 W5500 Ethernet examples with an automatic irrigation prototype based on STM8, ESP32 Wi-Fi, PHP, and Flutter. The W5500 section provides practical Ethernet and TCP validation examples, while the irrigation submodule shows a layered IoT structure with local control, gateway communication, backend scripts, and mobile-app scaffolding. The repository is best understood as a prototype-oriented embedded IoT project collection.

Full-Stack Embedded System: ESP32-S3 W5500 Ethernet 및 자동 관수 Prototype

프로젝트 개요

Full-Stack-Embedded-System은 단일 완성형 제품보다는 embedded IoT 예제와 prototype을 함께 정리한 저장소다. 구성은 크게 ESP32 기반 W5500 Ethernet 예제와 자동 관수 시스템 submodule로 나뉜다.

Ethernet_W5500는 MCU와 W5500 Ethernet module의 연결 방식을 다룬다. README는 ESP32 + W5500 Arduino 예제와 ESP-IDF 예제를 완료 상태로 표시하고, STM32 + W5500 지원은 planned 상태로 표시한다.

Automatic_Irrigation_System은 2022년 national startup competition 참여를 위해 개발된 자동 관수 프로젝트다. README는 local keypad control, timer 기반 scheduled irrigation, mobile application 기반 remote control을 주요 기능으로 설명한다.

시스템 구조

두 경로는 embedded IoT networking과 control이라는 공통 주제를 갖지만, 저장소 내에서 하나의 W5500 기반 자동 관수 gateway로 통합된 구조는 확인되지 않는다.

WIZnet Product Role

이 저장소에서 확인되는 WIZnet 제품은 W5500 Ethernet module이다. W5500은 ESP32 networking 예제에서 SPI 기반 Ethernet controller로 사용된다. Arduino 예제는 W5500 reset, chip select, SCLK, MISO, MOSI pin을 정의하고, SPI 초기화 후 Ethernet을 시작하며 TCP port 5000에서 server를 실행한다.

ESP-IDF 구현은 W5500 MAC/PHY 생성, SPI bus 설정, esp_netif, static IP 설정, lwIP socket API를 사용한다. TCP server는 socket, bind, listen, accept, recv, send 흐름으로 구성된다.

동작 흐름

W5500 Ethernet 흐름

1. ESP32-S3가 W5500 관련 GPIO와 SPI pin을 설정한다.
2. Arduino Ethernet library 또는 ESP-IDF Ethernet driver를 통해 Ethernet을 초기화한다.
3. DHCP 또는 static IP 방식으로 IP를 설정한다.
4. TCP port 5000에서 server를 실행한다.
5. PC client가 TCP로 접속해 데이터를 송수신한다.
6. Python client는 host 측에서 echo server 동작을 검증한다. 

자동 관수 흐름

1. STM8 controller는 keypad, LCD, RTC, watchdog, valve output 등 local control 요소를 담당한다.
2. ESP32 gateway는 Wi-Fi에 접속하고 PHP backend endpoint와 HTTP로 통신한다.
3. Backend에서 받은 control data는 UART를 통해 STM controller로 전달된다.
4. Sensor 및 valve state data는 backend로 전송된다.
5. Flutter mobile layer는 IoT 관련 dependency와 app scaffold를 포함한다.
