๐ Article Author: Ertu Electronics ๐ธ Follow our public account for more resources! ๐ธ Looking forward to learning and exchanging ideas together! 1. Introduction to SPI SPI stands for Serial Peripheral Interface, which is a high-speed, full-duplex, synchronous communication bus. It only occupies four pins on the chip, saving pin space while providing…
SPI (Serial Peripheral Interface) is one of the most widely used interfaces between microcontrollers and peripheral ICs (such as sensors, ADCs, DACs, shift registers, SRAM, etc.). SPI is a synchronous, serial interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. A common 4-wire interface is shown … Read more
Today, we will introduce the widely used SPI communication between PCB boards, striving to minimize the introduction of overly textual definitions and instead use straightforward language to explain. Definition: SPI (Serial Peripheral Interface) is a type of serial synchronous communication, which is mostly full-duplex (but it can also be half-duplex), primarily used in chips such … Read more

From “Dialects” to “Common Language”: The Translation Code Between PLC Brands Do you remember the awkward moment when I first switched from a Siemens project to a Mitsubishi project? Standing in front of the control cabinet, holding the program list, my mind was filled with the S7-300 instruction format, yet I had to understand the … Read more
The previous article introduced MQTT, but it felt like something was missing, so here is a complete overview. The Origin of MQTT Background: In the late 1990s, polling mechanisms were commonly used in the industrial control field to collect device data, but this method was inefficient and placed a high load on the network. At … Read more
In embedded software development, it is common to see friends defining custom protocols, mainly due to resource constraints and the relatively specialized functionality. Subsequent maintenance is also much simpler. However, at a certain stage or scale of the project, one must consider issues such as scalability and compatibility, leading to a variety of protocol designs. … Read more
Various communication protocols are used in automotive ECUs. Previous articles introduced several serial communication methods, such as: Understanding the SPI Protocol: Principles, Architecture, and Applications Understanding the I2C Communication Protocol Understanding the Differences Between I2C and SPI Buses Chassis Domain Control: Have You Heard of AK and PSI5? In this article, we will introduce another … Read more
Click the blue text Follow us 1. Overview CAN stands for Controller Area Network, which is an ISO standardized serial communication protocol and one of the most widely used field buses internationally. CAN communication uses only two signal lines, namely CAN_High and CAN_Low. The CAN controller determines the bus level based on the potential difference … Read more
