SPI (Solder Paste Inspection) refers to the solder paste inspection system, whose main function is to detect the quality of solder paste printing, including volume, area, height, XY offset, shape, bridging, etc. To quickly and accurately detect extremely small solder paste, detection principles generally use PMP (Phase Modulation Profile Measurement Technology) and Laser (Laser Triangulation … Read more
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
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
1. Introduction This small electronic badge contains many unique components. This AP Memory is a SPI interface SRAM with a capacity of 8MB. Below is a preliminary test of it. 2. Creating the Test Circuit This RAM with SPI interface operates with a current from 2.7V to 3.6V. Its package seems to be universal, similar … 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
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

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
