The microcontroller (MCU) in embedded systems is like the air traffic control system at a busy airport. The MCU can sense its working environment, take appropriate action based on the sensed results, and communicate with related systems. The MCU can manage and control signals in almost all electronic devices, from digital thermometers to smoke detectors to HVAC motors.
To ensure the economic efficiency and lifespan
Design Recommendations for ESD/EMI Protection in RK3588 Products
ESD: Electro-Static Discharge refers to the release of static electricity. Static electricity is a natural phenomenon that usually occurs through contact, friction, or induction between electrical devices. It is characterized by long-term accumulation, high voltage (which can reach thousands or even tens of thousands of volts), low charge, small current, and a short duration of action, often causing instability in electronic products or even damage.
EMI: Electromagnetic Interference refers to the disruption caused by electromagnetic waves. In high-speed PCB and system
Apple A11 Bionic Processor: Five Exclusive Technologies Inside!
In the iPhone 8, iPhone 8 Plus, and the upcoming iPhone X, Apple has used the latest A11 Bionic processor, which integrates a series of processing cores and complex controllers, each optimized for specific tasks. Currently, the known components include the new Apple GPU, neural engine, six-core, NVMe solid-state drive controller, and a new custom video encoder.
We need to understand these technologies one by one.

How to Install Desktop Linux on Windows for FPGA Development
Running EDA tools like Vivado on Linux is significantly faster than on Windows, likely due to optimization issues. Therefore, choosing to develop on Linux is a wise choice (mainly because it's free). In China, people are accustomed to the Windows system, so Linux is less commonly used. Is there a way to work on documents in Windows while also developing for FPGA on Linux?
The answer is: no, what are
How to Expand OpenWrt Overlay and Enable Swap
What is Overlay
Squashfs (.sfs) is a GPL open-source read-only compressed file system for Linux kernels. Squashfs can compress files, inodes, and directory structures within the file system.
Squashfs is designed specifically for general use in read-only file systems and can be applied to data backup or on computers with limited system resources.
The file system commonly used by OpenWRT is SquashFS, so it is recommended to download firmware that uses this file system.
The characteristics of this file system are: read-only and compressed.

Introduction to DFSDM Applications in STM32
Introduction
The STM32L4 series chips based on the Cortex M4 core in the ultra-low-power STM32 series integrate the DFSDM digital filter module, which, when used in conjunction with Σ-Δ devices, can perform high-precision and high-speed AD measurements. This article provides a basic introduction to DFSDM and demonstrates a practical application with the STM32L4 MCU.
