An In-depth Explanation of UART, I2C, SPI, and 1-Wire Communication Interfaces

An In-depth Explanation of UART, I2C, SPI, and 1-Wire Communication Interfaces

1. UART: The Lightness of Qiu Qianzhang’s Skills In “The Legend of the Condor Heroes”, Qiu Qianzhang says, “UART is like my lightness skill, floating over the water to cross the river.” To cross the river (communication), one must prepare in advance, setting markers at fixed intervals (baud rate predetermined). If the steps are too … Read more

In-Depth Explanation of UART/I2C/SPI/1-Wire Communication Interfaces

1. Qiu Qianzhang’s Lightness Skill: UART In “The Legend of the Condor Heroes”, Qiu Qianzhang says, “UART is like my lightness skill, gliding over the water to cross the river.” To cross the river (communication), one must set up hidden stakes in advance, and while moving, the steps must be fixed according to the distance … Read more

Oscilloscope Practical Series: 1-Wire Protocol Trigger

Oscilloscope Practical Series: 1-Wire Protocol Trigger

Hello everyone, in the last video we shared the decoding of the 1-wire protocol, today let’s take a look at its trigger function. Once the protocol trigger is turned on in the decoding module, after pressing the [Trigger] button, the trigger type automatically changes to the decoded 1-wire protocol. Set the trigger mode to normal, … Read more

Summary of Common Communication Interfaces in Embedded Development

In embedded systems, on-board communication interfaces refer to the communication pathways or buses used to connect various integrated circuits with other peripheral devices. The following content summarizes commonly used on-board communication interfaces: including I2C, SPI, UART, and 1-Wire: I2C Bus The I2C bus is a synchronous, bidirectional, half-duplex two-wire serial interface bus. Here, half-duplex means … Read more
