1. STM32 and Selection 1.1 STM32 vs 51 Microcontroller Both STM32 and 51 are types of small computer chips that allow us to write code and store it within. For example, we can control a pin to switch between 5V and 0V, connecting an LED to this pin to achieve a blinking effect. This operation … Read more
What Is Impedance? Isn’t It The Same As Resistance? Regarding impedance (Impedance), I have found that many newcomers to this concept often confuse it with resistance (Resistance). This confusion may arise because both terms contain the character for “resistance” in Chinese, and both units are expressed in Ω. Additionally, impedance and resistance are related to … Read more
Introduction With the growing demand for networking, the issue of gigabit Ethernet speed has garnered significant attention. This article analyzes the low actual speed situation, detailing reasons such as poor wiring, and provides effective methods for improving speed and stability from both hardware aspects like equal-length wiring and impedance matching, as well as software debugging … Read more

2016-11-24 Introduction Developing mobile handheld devices with touch screen human-machine interfaces is a complex design challenge, especially for projected capacitive touch screen designs, which represent the mainstream technology for current multi-touch interfaces. Projected capacitive touch screens can accurately locate the position of a finger touching the screen by measuring the minute changes in capacitance to … Read more
Introduction I previously envisioned a mobile storage device based on the ESP32, and now I am attempting to create a prototype. The first step, I believe, is to design a dedicated PCB. I previously used an ESP32S3 development board to test how to run WebDAV, but the flash memory on the development board only has … Read more
This course series uses the RK3588 chip as the core basis for hardware design, based on the latest version of Cadence Allegro Allegro X software, to conduct a complete flow of design and simulation for system on-chip resources, interface circuit design, and various commonly used peripheral resources for chip expansion. The latest software features and … Read more
Today, I have compiled some prices of commonly used software tools in embedded development, and some netizens exclaimed: The cost of embedded development is too high! Let me ask everyone first: Do you think the cost of embedded development is high? The answer: Yes! For ordinary people, it is indeed high, except for some wealthy … Read more
I got a car board from a friend, and the main appearance is as follows. Car controllers usually use metal housings to shield strong interference, allowing the system to operate more stably. Today, we will mainly dissect this board to see what functional parts it has. Opening the lower part of the housing, the back … Read more
