Introduction to SPI Interface and Features The standard SPI interface has 4 signal lines. Signal Function Direction SCLK Clock signal line, used for synchronizing communication data master->slave MOSI Master device output master->slave MISO Master device input slave->master CS Slave device select signal line, commonly referred to as chip select signal line, also known as NSS, … 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

01 【SPI Concept】 SPI (Serial Peripheral Interface) is a synchronous serial port for communication between microcontroller units (MCUs) and peripheral ICs (such as sensors, ADCs, DACs, driver chips, and external storage devices). The communication rate can range from a few thousand bps to hundreds of Mbps or even higher, depending on the specifications and performance … Read more
01 【Introduction】 SPI: Serial Peripheral Interface, is a synchronous serial interface for device communication. SPI was developed by Motorola around 1985 and is suitable for short-distance, device-to-device communication. Since then, this interface has become a de facto standard adopted by many semiconductor manufacturers, especially microcontrollers (MCUs) and microprocessors (MPUs). 02 【SPI Interface】 The SPI bus … Read more
Recently, I needed to write a protocol, so I reviewed SPI again. (I have kept this draft for too long, if I don’t publish it now, I will forget it) First, I analyzed the characteristics of the SPI protocol, using the ADS1118 device as a carrier for analysis. Later, I used a logic analyzer to … Read more
1. Introduction to SPI SPI, short for Serial Peripheral Interface, is a serial communication interface defined by Motorola for its MC68HCXX series processors. The SPI interface is mainly used between EEPROM, FLASH, real-time clocks, AD converters, as well as digital signal processors and digital signal decoders. SPI is a high-speed, full-duplex, synchronous communication bus that … Read more
