In the assembly language of the ARM processor, the constant expression of shifter_operand in the instruction syntax format has the following provisions: "The constant must correspond to an 8-bit bitmap, that is, the constant is obtained by cyclically shifting an even number of bits of an 8-bit constant." First,
Braking of three-phase asynchronous motors is an important topic in the field of motor control. In practical applications, motors need to start, run, stop and other operations under different working conditions, and braking is one of the important means to achieve these operations. This article will introduce the br
CAN bus (Controller Area Network) is a fieldbus communication protocol used in the automotive and industrial automation fields. It has high reliability, real-time and flexibility, and is widely used in communication between various electronic control units (ECUs). In practical applications, in order to extend the le
As the global demand for electric vehicles (EVs) continues to grow, drivers are increasingly demanding vehicle performance. They expect longer driving range and faster charging speeds, which are closely related to battery performance. Therefore, optimizing battery technology has become the key to improving the perfo
Suzhou Oliwen New Energy Technology Co., Ltd. (hereinafter referred to as "Oliwen New Energy") recently announced the completion of tens of millions of angel round financing, led by Tongchuang Weiye. Aoliwen New Energy has made significant progress in the research and development of core diaphragm materials in
On October 21, according to media reports, TSMC Chairman and CEO Wei Zhejia recently confirmed that the demand for artificial intelligence (AI) is "real", and said that TSMC is expected to achieve continuous and healthy growth in the next five years. Customers have more inquiries about 2nm than 3nm, which seems to b
During the live broadcast between Yu Chengdong and Ma Dong, Ma Dong asked Yu Chengdong, is lidar necessary? Yu Chengdong said that we insist on using LiDAR because of its safety. If you only use the camera solution without the LiDAR solution, the camera will cause blindness. There are some thin
Application technology: Rain, light, sunlight, temperature and humidity sensor Application field: Intelligent cockpit Unique advantages: ① The rain sensitivity sensing area reaches 210mm, which is the largest designed in the industry.
Circuit Principle In Figure IC1-4069, Y1 and Y2 form an oscillator with a frequency of 76KHZ. After being isolated and shaped by Y3-Y6, they are sent to the two-group frequency modulation circuit composed of IC2 dual JK flip-flop CD4027 to generate symmetrical square waves of /-38KHZ and 19KHZ. The square wave of /-
During the peak summer period, the 100MW/200MWh grid-side energy storage power station invested and built by the Blue Sky Power Plant officially responded to the grid dispatching requirements, completed the peak-shaving charging and discharging work every day, and participated in the peak-shaving and valley-filling
Recently, the Three Gorges Binhai Energy Storage Project has been successfully connected to the grid at full capacity and put into operation. It is reported that the project is currently the largest string energy storage power station in China. As the core supplier of equipment for this project, Haichen Energy Stora
1. Introduction to PLC PLC, full name Programmable Logic Controller, is an electronic device used for industrial automation control. It controls the operation of machines or equipment through pre-written programs. The main functions of PLC include input/output interface, counter, timer, relay, etc. Due to its h

S7-1200 V4.0 and above firmware versions of the CPU support intelligent IO device functions, so you can use S7-1200 as an intelligent IO device and S7-300 PN CPU for Profinet communication. In this example, the S7-300 is used as a controller and connected to the S7-1200 CPU as an intelligent IO device to achieve Pro
In recent years, technological advances have led to increasingly sophisticated systems and devices for measuring brain activity in research and medical settings. One concept that has been widely explored but not yet effectively implemented is collecting electroencephalogram (EEG) measurements while people navigate v
1 Device resource initialization Linux-2..6.32.2 already comes with a complete DM9000 network card driver (source code location: linux-2.6.32.2/ drivers/net/dm9000.c). It is also a platform device. Therefore, in the target platform initialization code, just fill in the corresponding structure table. The
Recently, a news report about one of the three major Japanese automobile brands that will be connected to Huawei's intelligent driving system attracted Xiaowen's attention. Blogger @孙少军09 has just revealed that one of the three major Japanese car brands (which one is still a secret) will soon be con
(1) What settings are required when Siemens 200 PLC uses MPI protocol to communicate with KingView? 1) The STEP7Microwin3.2 programming software provided by Siemens needs to be installed on the machine running Kingview. Our driver needs to call the MPI interface library function provided by the programming soft
The correct selection of the inverter is critical to the normal operation of the control system. When selecting an inverter, you must fully understand the load characteristics driven by the inverter. In practice, people often divide production machinery into three types: constant torque load, constant power load and
