The UART (Universal Asynchronous Receiver/Transmitter) is a serial communication device that serves as a bidirectional, serial, asynchronous communication bus. It can achieve full-duplex communication using one data receiving line (RX), one data transmitting line (TX), and a ground line (GND). As shown in the figure below: When communicating using UART, the unit of transmission is … Read more
Ensuring system scalability is one of the core goals of our architectural design work. There are many ways to achieve scalability, and the JDK itself has a built-in SPI (Service Provider Interface) mechanism to help developers dynamically load various implementation classes, as long as these implementation classes follow certain development specifications. On the other hand, … Read more
1. Comparison of Communication Speeds: SPI, I2C, UART SPI > I2C > UART 1. Synchronous communication > Asynchronous communication; 2. In synchronous communication, a clock line must connect both ends of the transmission; 3. All are serial communication methods, while parallel communication is used for internal storage communication, such as flash; 4. The suitable transmission … Read more
The Electronic Enthusiast Network reports (by Wu Zipeng) that position sensors play a critical role in the industrial sector, capable of detecting parameters such as the position, displacement, distance, and angle of objects, thereby enabling automation control, precise positioning, and status monitoring. With continuous technological advancements, the application scenarios for position sensors are becoming increasingly … Read more
01 Dry Chemical Analysis Technology Dry chemical technology is compared to traditional wet chemical technology, where the liquid present in the sample serves as the reaction medium. The components to be measured react directly with dry reagents fixed on a carrier, allowing for qualitative observation or instrument detection (semi-quantitative) for chemical analysis. Single-layer Test Paper … Read more
1. Mold Design and Optimization In the production process of dry pressed ceramic sensors, the design and optimization of molds have a crucial impact on the dimensional accuracy of the products. The mold not only determines the shape and size of the product but also directly affects the flowability of the powder and the uniformity … Read more
High computing power and abundant sensors: The FAW Toyota bZ5 tackles Beijing’s evening rush hour. If you still think that joint venture new energy vehicles are just “oil-to-electric conversions with reduced configurations,” you really need to take a look at the bZ5. Honestly, this newly launched “dark horse of joint ventures” has almost completely overturned … Read more
Respect for originality 1. Research Objective: Currently, the reference values for regional cerebral oxygen saturation (rScO2) in preterm infants across different gestational age groups are not well defined. This study aims to establish reference ranges for rScO2 in preterm infants born at <32 weeks of gestation. 2. Study Design: A prospective observational cohort study. 3. … Read more
