TCP/IP (Transmission Control Protocol/Internet Protocol) is the most fundamental protocol of the Internet, forming the basis of the global interconnected network. It consists of two main parts: the IP protocol at the network layer and the TCP protocol at the transport layer. These two protocols work together to ensure that data can be accurately transmitted … Read more
1 Introduction CAN stands for Controller Area Network, which is a serial communication network capable of achieving distributed real-time control. Advantages: The transmission speed can reach up to 1 Mbps, with a maximum communication distance of 10 km, a lossless arbitration mechanism, and a multi-master structure. In recent years, the price of CAN controllers has … Read more
1 Serial Peripheral Interface (SPI) Protocol Overview SPI is a multi-master or master-slave, four-wire, full-duplex synchronous serial communication protocol, which means that data can be sent and received simultaneously.SPI was developed by Motorola as a protocol for synchronous serial communication, allowing full-duplex communication between two or more devices, which can be designated as master or … Read more

1. Overview PROFIBUS-DP, where DP stands for Decentralized Periphery, is a type of computer electronic component. It features high speed and low cost, used for communication between device-level control systems and decentralized I/O. It, along with PROFIBUS-PA (Process Automation) and PROFIBUS-FMS (Fieldbus Message Specification), constitutes the PROFIBUS standard. 2. Basic Information Specifications The PROFIBUS-DP protocol … Read more
Click the aboveblue text to follow us In embedded systems, the Serial Peripheral Interface (SPI) and its extensions (such as DSPI and QSPI) are widely used for high-speed communication with external devices (such as sensors, memory, LCD controllers, etc.). The main differences are as follows: 1 SPI SPI (Serial Peripheral Interface) is a full-duplex synchronous … Read more
