RS-485 Communication Protocol

by
RS-485 Communication Protocol

RS-485 Communication Protocol Overview The typical serial communication standards are RS-232 and RS-485, which define voltage, impedance, etc., but do not specify software protocols. The RS-485 bus standard defines the electrical characteristics of the bus interface, specifically the definitions for two logic states: a positive level between +2V and +6V represents one logic state, while … Read more

Working Principle of Accelerometers

Working Principle of Accelerometers

What is a Sensor? A sensor is essentially a device or apparatus that can “convert physical quantities.” To obtain information for detection and control, it is necessary to convert the state, properties, and physical changes of an object into electrical quantities, using various physical laws for this conversion. Representative physical quantities that sensors detect and … Read more

Embedded Linux Development Log (4)

Currently, most industrial control systems are embedded systems (a few simple systems use bare metal development directly). An “embedded system” refers to a computer system with specific functions embedded within specific hardware. Embedded systems generally consist of a real-time operating system (RTOS) + application software (a PLC itself is also an embedded system). Common real-time … Read more
