01 IIC Bus (Inter－Integrated Circuit) I2C (Inter-Integrated Circuit), also known as IIC or I2C bus, is a serial communication protocol used to connect multiple devices over short distances. It was first introduced by Philips in 1982 and is now widely used for communication between embedded systems, sensors, memory, and other peripheral devices. Here are some … Read more

Click the blue words Follow us 1. Introduction 1. Concept USART (Universal Synchronous Asynchronous Receiver Transmitter) is a serial communication device that can flexibly perform full-duplex information exchange with external devices. UART (Universal Asynchronous Receiver/Transmitter) is a bidirectional, serial, asynchronous communication bus that can achieve full-duplex communication using only one data receiving line (RXD) and … Read more
Serial communication methods such as ART, SPI, and I2C are very common in embedded development. The underlying principles of these communications are not difficult, but many beginners struggle to understand them. Today, I will share some common underlying data transmission principles of these communication methods. 1UART Serial Port UART: Universal Asynchronous Receiver/Transmitter. The UART serial … Read more
1. Serial Port Activation Process Before we start, let’s take a look at a few demo programs for serial ports from different chips. These include the STM32 V3.5 standard library, the official demo for nRF52832, and the official DEMO for the STC15 series microcontroller with a 51 core. From the above demo examples and the … Read more

The “Marriage” of Embedded Systems and Communication Protocols In today’s wave of digitalization, embedded systems are like a magical “behind-the-scenes hero,” quietly penetrating every aspect of our lives. When you drive a car, the embedded system in the engine control system accurately adjusts fuel injection and ignition timing, ensuring efficient and stable power output; the … Read more
Communication protocols designed for embedded devices typically fall into three categories: Considering the limited memory and computing power of embedded devices, fixed binary is the preferred communication protocol. The following analyzes the characteristics that embedded device communication protocols should have. Simplicity Ensuring that the protocol is a simple solution is crucial; complexity often leads to … Read more
Previously, we introduced how to create a logic analyzer and oscilloscope using RP2040. Today, we will build a logic analyzer using FPGA. Currently, the mainstream architecture of logic analyzers in China is based on FPGA + USB PHY. The combination of the advantages of FPGA and the high accessibility of USB has kept it in … Read more
