This tutorial presents PIO-based stepper motor control on the Feng No.1 board. Different from blocking GPIO software delay driving, the independent PIO

This project builds a remote camera system around an STM32F4 MCU, an OV2640 image sensor, and a WIZnet W5500 Ethernet controller.

This project connects FPGA logic on a Zynq platform directly to a Windows TCP application using the WIZnet W5500 over SPI.

ESP32-S3 aeroponic controller combining W5500 Ethernet, Wi-Fi, RS485 and ESP-NOW for irrigation, lighting, climate and logging.

An RP2040/W5500 bridge that forwards Dutch smart-meter P1 serial telegrams to multiple TCP clients with web, logging, NTP and OTA services.

STM32 monitors vibration, temperature, and current, detects equipment faults with FFT and thresholds, and reports them via Modbus RTU.

MicroPython RTK base station on W5500-EVB-Pico2. RTCM3 from a UM980 streams to an NTRIP caster while a status server and telemetry share the W5500's sockets.

QuackPLC uses W5500 hardware TCP to serve OPC UA while keeping its 1 kHz PLC scan timing stable without lwIP or an RTOS socket layer.
