Understanding The Differences And Applications Of SPI, UART, And I2C Communication

Source: Network Communication between electronic devices is like communication between humans; both parties need to speak the same language. In electronic products, these languages are called communication protocols. I previously shared articles on SPI, UART, and I2C communication separately, and this article compares them. Serial VS Parallel Electronic devices communicate by sending data bits back … Read more

Buses, buses, they always trap you inside. All the signals in the world are the same, but there are thousands of buses, which can be quite a headache. In general, there are three types of buses: internal buses, system buses, and external buses. The internal bus is used for interconnecting peripheral chips and the processor … Read more

Having memorized a lot of stock responses, I believe everyone has heard the term SPI Extension. Some interviewers really like to ask this question: How is Spring Boot’s auto-configuration implemented? Basically, if you mention that it is based on Spring’s SPI extension mechanism and bring up the spring.factories file and EnableAutoConfiguration, then you are likely … Read more

Detailed Explanation of SPI

1 Introduction to SPI SPI, short for Serial Peripheral Interface, is a synchronous serial communication protocol. It was first defined by Motorola for its MC68HCXX series processors. The SPI interface is primarily used in EEPROM, FLASH, real-time clocks, ADCs, as well as between digital signal processors and digital signal decoders. SPI is a high-speed, full-duplex, … Read more

Some things can only be done alone. Some doors can only be passed alone. Some roads can only be walked alone. 1. Overview SPI: Serial Peripheral Interface. It is a synchronous serial bus interface specification developed by Motorola in the mid-1980s (with clock signal, controlled by clock polarity and clock phase for sampling, that is, … Read more

What is SPI SPI stands for Serial Peripheral Interface in English, which, as the name suggests, is a serial peripheral device interface. It was first defined by Motorola in its MC68HCXX series processors. SPI is a high-speed, full-duplex, synchronous communication bus that only occupies four lines on the chip’s pins, saving pin space and providing … Read more

Hello everyone, I am Su San~~ Today I would like to discuss the SPI mechanisms of Java, Spring, and Dubbo, focusing on their principles and differences. Actually, I have previously written a similar article, but that one mainly analyzed the source code of Dubbo’s SPI mechanism, only briefly introducing the SPI mechanisms of Java and … Read more
