Modbus RTU/TCP Protocol Stack on STM32

A complete Modbus RTU and TCP protocol-stack implementation for STM32, designed to be reused across industrial communication, the ROV multi-node bus, smart metering, and engine-control integration.

Across the ROV, smart metering, and engine-control work, the same need kept recurring: reliable, standards-correct Modbus communication. Re-implementing it per product is wasteful and a constant source of subtle, hard-to-debug field issues.

One portable, reusable Modbus stack

• A full Modbus RTU (RS-485) and Modbus TCP/IP implementation for STM32
• A clean register-map abstraction and master/slave roles so it drops into new products
• Integrated into the ROV multi-node bus, smart metering, and ECU rather than rebuilt each time

• A reusable communication building block shared across multiple industrial products

Add to confirm: which products shipped it, throughput, and max nodes supported.
