Have you ever wondered how that tiny microcontroller, smaller than a fingernail, manages to control smart homes, remote-controlled cars, and even drones? Today, let’s unveil its mysterious veil together. I remember the first time I got my hands on a microcontroller, staring at that small black square for a long time. It looked so simple, … Read more
The Extension of Human Perception Sensors Foreword Introduction You may not realize that when you are awakened by the vibration of a smart wristband in the morning, it is the accelerometer sensing your sleep cycle; when your phone automatically focuses while taking a picture, it is the distance sensor capturing the distance to the scene; … Read more
Piezoelectric accelerometers operate based on the piezoelectric effect, generating charge signals through the inertial force acting on the piezoelectric element from a mass block, achieving electromechanical conversion of acceleration. 1、Working Principle and Core Mechanism The core principle of piezoelectric accelerometers is to utilize piezoelectric materials to convert mechanical vibrations into electrical signals. The specific process … Read more
A microcontroller is essentially a small computer, and just like a large computer, it requires a data storage system. Microcontrollers have this capability, often integrated with the CPU, making them compact and flexible.Until the early 1990s, the most accessible microcontroller in China was the 8031: a chip without built-in memory, requiring external RAM and ROM … Read more
01ROM Design and Implementation Based on Vivado Core In FPGAs, ROM is a very important module that allows complex data to be output based on address information. Vivado is a high-level design suite from Xilinx used for the design and verification of FPGAs (Field Programmable Gate Arrays). In Vivado, we can use high-level design methods … Read more
For those new to microcontrollers, the terms “ROM” and “RAM” can be quite confusing. Both are storage areas, but why are they divided into two? Some say ROM is “dead memory” and RAM is “live memory”; while this is not incorrect, it is too vague. Whether it’s the 51 microcontroller, STM32, or the ATmega328P used … Read more
In the world of microcontrollers (also known as microcontrollers), ROM (Read-Only Memory) and RAM (Random Access Memory) are two important storage components, each playing an indispensable role, often found alongside engineers. Today, let’s discuss what ROM and RAM are, their uses, and more. 1. What is ROM? ROM, or Read-Only Memory, is a type of … Read more
In vibration testing, vibration sensors serve as the most sensitive devices at the forefront of the testing system, and their stability and accuracy affect the results of the entire test. Therefore, how to select the appropriate sensor becomes very important. This article will introduce some selection tips for vibration accelerometers based on over 30 years … Read more
Have you ever been puzzled by the phenomenon where, after discussing a product with a friend on your phone, you suddenly see related recommendations flooding your shopping app? Is it possible that the phone is actually “listening” to our conversations? In the past, we might have suspected that microphone permissions were being abused, but now, … Read more
