WIZnet W5500 C Library (FreeRTOS) for Embedded Ethernet — AMIRAFRASIAB/W5500
WIZnet W5500 client/driver repo with Client/Driver/Example/FreeRTOS/Official folders and a 1.0.0 tag noting a completed FreeRTOS driver.

Introduction
This repository provides a C-language codebase for the WIZnet W5500 Ethernet Controller, with top-level folders Client/
, Driver/
, Example/
, FreeRTOS/
, and Official/
. The repo description says “Specially for CM4,” and the 1.0.0 tag states “FreeRTOS Driver completed and doxygen comments added.” GitHub
WIZnet product integration
Target device: WIZnet W5500 Ethernet Controller (hardware TCP/IP over SPI).
Evidence: presence of Driver/
and FreeRTOS/
plus the 1.0.0 tag note about a FreeRTOS driver. GitHub
Software stack overview
Languages: C 100% (GitHub panel).
Structure: Client/
, Driver/
, Example/
, FreeRTOS/
, Official/
.
Versioning cue: Tag 1.0.0 with the FreeRTOS driver message. GitHub
Build & toolchain — actionable path
Clone and checkout the 1.0.0
tag.
Inspect public headers in Driver/
and FreeRTOS/
for SPI and CS/INT/RESET hooks.
Add a minimal CMake/Make in your application to compile the driver plus one file from Example/
as a smoke test.
If using FreeRTOS, define task stack/priority for W5500 I/O accordingly. (Build scripts are not published in the repo page.) GitHub
Configuration & runtime pointers
Wire your board’s SPI device and GPIO for CS / INT / RESET to the driver’s expected hooks.
Add DHCP/static IP bring-up in your app if not present in examples.
Reproduction checklist
Clone → git checkout 1.0.0
→ add Driver/
(and FreeRTOS/
) to your app → wire SPI/GPIO → run a minimal TCP send/recv test. GitHub

구성 & 런타임
보드의 SPI, CS/INT/RESET GPIO를 드라이버 훅에 매핑.
DHCP/Static 초기화가 없다면 애플리케이션에서 보강.
재현 체크리스트
클론 → git checkout 1.0.0
→ Driver/
(필요 시 FreeRTOS/
) 포함 → SPI/GPIO 매핑 → TCP 송수신 스모크 테스트. GitHub
