The SPI (Serial Peripheral Interface) communication protocol is a high-speed, full-duplex, synchronous, master-slave architecture serial communication protocol that uses only four signal lines. It is widely used for data transmission between MCUs/FPGA and peripherals (such as DACs, ADCs, Flash, and EEPROM).This article will explain the SPI communication protocol in three parts: the physical layer, protocol … Read more
Click the blue text Follow us 1. Introduction to SPI Protocol The SPI protocol, proposed by Motorola, is a communication protocol (Serial Peripheral Interface) that allows chips to communicate with external devices in half/full duplex, synchronous, and serial modes. This interface can be configured as a master mode and provides a communication clock (SCK) for … Read more

The I²C (Inter-Integrated Circuit) protocol was developed by Philips Semiconductors (now NXP Semiconductors) and released in 1982. It is a serial, half-duplex bus primarily used for communication between chips over short distances at low speeds. The I²C bus consists of two bidirectional signal lines: one data line (SDA, serial data) for sending and receiving data, … Read more
UART (Universal Asynchronous Receiver/Transmitter) is the most common and simplest communication method in the embedded world. Its core idea is: parallel data input → serialized bit stream by frame → the receiver samples and recovers at the same baud rate. It is simple to implement and low in cost, but has limited scalability. This article … Read more
SPI Communication Protocol SPI Control Mode SPI adopts a master-slave control mode. A master device can control multiple slave devices by providing a clock and selecting the slave device. The SPI protocol also specifies that the clock for the slave device is provided by the master device through the SCK pin, and the slave device … Read more
