UART, SPI, and I2C are very common serial communication methods in embedded development. The underlying communication principles of these protocols are not difficult, but many beginners struggle to learn them. Today, I will share some common underlying data transmission principles of these communication methods. UART Serial Communication UART: Universal Asynchronous Receiver-Transmitter. The UART serial port … Read more

In this article, we will introduce the basics of digital communication and the Serial Peripheral Interface (SPI) communication. This includes the communication structure and the required digital lines.Many precision analog devices have digital interfaces between microcontrollers (referred to as controllers) and controlled devices (referred to as peripherals). For example, a precision Analog-to-Digital Converter (ADC) measures … Read more
The full English name of SPI is Serial Peripheral Interface, which, as the name suggests, is a serial peripheral interface.SPI is a synchronous serial communication interface specification primarily used for short-distance communication in embedded systems.This interface was developed by Motorola in the mid-1980s and has since evolved into an industry standard.SPI is a high-speed, full-duplex, … Read more
The Serial Peripheral Interface (SPI) 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, full-duplex, master-slave interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. Both the master and … Read more
1. Overview of SPI Communication SPI (Serial Peripheral Interface) is a synchronous serial communication protocol developed by Motorola (now NXP), primarily used for short-distance, high-speed communication between master and slave devices. Its features include full-duplex transmission, master-slave architecture, and no complex protocol layers, making it widely used in embedded devices such as memory (e.g., Flash), … Read more
1. Introduction to SPI SPI, which stands for Serial Peripheral Interface, is a synchronous serial communication protocol originally defined by Motorola for its MC68HCXX series processors. The SPI interface is primarily used for communication between EEPROMs, FLASH memory, real-time clocks, ADCs, as well as digital signal processors and digital signal decoders. SPI is a high-speed, … Read more
