Kontrx Edge Gateway — How an Industrial Water-Quality Controller Puts the W5500's Hardware Sockets to Work Kontrx is a bare-metal STM32F407 + FreeRTOS industrial edge gateway for water-quality monitoring. It doesn't just "have Ethernet" — it runs three independent TCP roles simultaneously on a single WIZnet W5500: an HTTP dashboard server, an MQTT publisher, and a Modbus TCP client talking to remote PLCs. All three share the same SPI bus and the same chip's socket pool, arbitrated by a recursive mutex confirmed at the code level. Overview Field-level water-quality monitoring — pH, ORP…
