According to Beijing Fangshan, on October 17, Beijing Weilan High-Performance Solid-State Lithium-Ion Battery Mass Production Project, a key project in Beijing, officially started. The project is planned to be built in three phases, focusing on the layout of low-altitude power, new energy vehicles an

On September 9, according to the Deputy Chief Minister of Maharashtra, India, Devendra Fadnavis, Beijing time on the 5th of this month, the Indian giant Adani Group and the Israeli wafer foundry Tower Semiconductor plan to build a wafer factory in the state. The wafer fab will be located in Panvel near Mumbai,

The increasing complexity of smart driving and smart cockpits is driving SoC design into a new stage of development. How to design better SoC chips through new centralized regional architectures, SoC designs that integrate AI technology, and advanced interface IP (intellectual property) technology. Traditional autom

Purpose: Add a simple driver directory mytest under the drivers directory, and obtain the corresponding configuration items in the make menuconfig configuration panel. Since the compilation step is not involved for the time being, only one Kconfig is added to mytest, and no corresponding code files and Makefile ar

1. The difference between embedded and single-chip microcomputer From the software perspective, the industry often calls the system that does not have MMU (Memory Management Unit) in the chip and therefore does not support virtual addresses, and can only run naked or RTOS (real-time operating system, such as uc

Assembly Example MAIN: MOV R0, #16 MOV R1, #16 LOOP: MOV A, R1 MOV @R0,A MOV A,0x0 MOV A, @R0 MOV SBUF, A INC R0 INC R1 CJNE R0, #255 , LOOP NOP

Because the substrate of a MOS transistor is either connected to the source or to VDD or VSS, it is often used as a three-terminal device. Since the threshold voltage of future CMOS technology will not be much lower than the current standard, the use of substrate-driven technology for analog circuit design becomes a

The servo motor of a CNC machine tool is an important power drive device in the CNC system, which is crucial to ensure the stability and accuracy of the machine tool. If a fault occurs, timely maintenance is essential. The following is a list of some common CNC machine tool servo motor faults and their maintenance m

The integration of low-frequency and high-frequency RF wireless systems is very different. In the high-frequency band, CMOS technology is the preferred technology for RF circuits because it can achieve higher bandwidth than bipolar technology. Usually RF-CMOS is not integrated with digital CMOS on the same chip. The

According to foreign media reports, the Alliance for Automotive Innovation, which represents almost all other automakers such as General Motors, Toyota, Volkswagen, etc., asked the National Highway Traffic Safety Administration (NHTSA) to reconsider the regulations issued in April this year that by 2029, almost all

The humidity sensor used in the simulation is SHT11. SHT11 is a digital temperature and humidity sensor chip launched by Swiss Scnsirion Company. The chip is widely used in HVAC, automotive, consumer electronics, automatic control and other fields. Its main features are as follows: Highly integrated, integrating f

DMA (Direct Memory Access) is often translated as "direct memory access". DMA applications have been available as early as Intel's 8086 platform. A complete microcontroller usually consists of components such as CPU, memory and peripherals. These components are generally independent in structure and function, and th

The modern world is gradually adopting more natural human-machine interfaces (HMI). Not only can we talk to smart speakers, we can also read on paper-like e-readers. Electronics have become our digital companions, no longer systems limited by power sockets. Achieving this revolution requires multi-core proce

The Ryzen 7040 series processors released by AMD in early 2023 not only bring the most advanced 4nm manufacturing process, Zen4 CPU architecture, and RDNA3 GPU architecture to notebooks, but also add independent NPU AI engine hardware to x86 processors for the first time unit. This is Ryzen AI, which also created the

Driven by a new round of global technological revolution and industrial transformation, the automobile industry has ushered in major changes unseen in a century and is accelerating its transformation and upgrading to intelligent, networked and new energy sources. From November 1st to 3rd, AUTO TECH 2023 Guangzhou Inte

Vacuum systems are widely used in industries such as electric power, petrochemicals, medical pharmaceuticals, plastics, environmental protection, and medical equipment. With the continuous expansion and deepening of vacuum application fields, the requirements for vacuum technical indicators are becoming higher and hig

The board is GQ2440 made by China Embedded Technology Co., Ltd. For the main transplantation steps, please refer to Mr. Wei Dongshan’s "Complete Manual of Embedded Linux Application Development" 1. Download the kernel and apply patches 2. Use config_ok to configure the kernel. 3. Modify the value of MACH_TYPE_S3C2440

The usable address space of s3c2440 is 1GB (0x00000000 to 0x40000000). 1G space is divided into 8 BANKs, each BANK is 128MB. Assume 27 address lines and 8 chip select pins (nGCS0-nGCS7). The memory controller automatically determines the chip select pin to be used based on the BANK where the address is located to enab

When designing inductive components containing magnetic core materials, engineers must accurately measure the material's properties. The core's dynamic hysteresis loop (or BH curve) contains valuable information about core losses and other magnetic parameters. Unfortunately, commercial magnetic circuit analyzers are e
