Click the blue text Follow us Bit Time and Bit Synchronization in CAN Communication In CAN communication, Bit Time refers to the time required to transmit one bit on the bus, which is the reciprocal of the CAN bus communication rate (baud rate). CAN communication ensures reliable data transmission by sampling and synchronizing the signal … Read more
The serial port enables reliable communication between two terminal devices, functioning as the transport layer in this process. This article focuses on the data protocol. Similar Scenarios Hey! Hey! This is Dong Guai! Please respond! Please respond! over! Such dialogues are often seen in war-themed films when calling teammates through walkie-talkies or related wireless devices. … Read more
Embedded devices need to set parameters during operation, which is often accomplished by a PC. A communication protocol must be designed for both parties, with three representative protocols as follows: As can be seen from the table above, embedded devices generally have limited memory and computational performance, so fixed binary is the preferred communication protocol. … Read more
‖ System Learning Life is like a marathon; sometimes you need to take a break to go fishing to go further. Hey! It’s time for a break again. A couple of days ago, I shared about Understanding a Communication Protocol: PROFINET Understanding a Communication Protocol: PROFIBUS Today, let’s learn about the new CANopen communication protocol. … Read more
Click the blue text Follow us 1. Introduction 1. Concept The SPI (Serial Peripheral Interface) bus protocol is a full-duplex synchronous serial bus communication protocol used for data transmission between integrated circuits. The SPI bus typically consists of one master device and multiple slave devices, each slave device has a separate chip select signal, and … Read more
Click the Blue Text Follow Us 1. Introduction 1. Concept The IIC protocol (I²C, or Inter-Integrated Circuit) is a widely used low-speed serial half-duplex communication protocol for communication between integrated circuits, allowing only unidirectional communication at any one time. It was invented by Philips in the 1980s and is widely used for data transmission between … Read more
In embedded development, it is common to define custom protocol formats, such as for communication between boards or between client and server. There can be many types of custom protocol formats. In this article, we will introduce a commonly used, practical, and highly flexible protocol format—ITLV format. 01 【What Is ITLV Format?】 You may have … Read more
