I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino uses isn’t the ideal teaching language. Those of us who remember ...

在工业物联网设备开发中，Modbus从站功能已成为微控制器（MCU）的标配能力。某智能电表项目通过在STM32上实现Modbus RTU从站，成功将设备接入现有SCADA系统，开发周期缩短40%。本文将系统解析MCU实现Modbus从站的关键技术路径，涵盖硬件配置、协议解析、库函数应用等核心环节。

在工业自动化领域，Modbus协议凭借其简单可靠的设计成为设备互联的"通用语言"。从PLC到智能传感器，从能源管理系统到楼宇自控，超过80%的工业设备通过Modbus实现数据交换。其核心在于四种基础数据类型与寄存器分类的精妙设计，这种设计既保证了通信效率，又满足了工业场景的多样化需求。
