Neuro and Evil fun time pid:126363594 by:Wimo Yes, that’s right, I2C has also been discussed in the Microelectronic System Click here to view the Microelectronic System review: I2C Background Knowledge Parallel Transmission and Serial Transmission Parallel Transmission Transmits multiple bits at once, usually using multiple data lines simultaneously. Serial Transmission Transmits one bit at a … Read more
Hug pid:131183771 by:White It is still discussed in the Microelectronic System Click here to view the Microelectronic System review: SPI The specific transmission details of SPI are clearly explained there, so I will briefly mention it here without going into detail. Overview SPI is a synchronous communication protocol developed by Motorola in the 1980s, primarily … Read more
silly pid:113107781 by:paccha!! DAC (Digital to Analog Converter, 数模转换器) DAC 基础部分 The function of a DAC is to convert digital signals into analog signals. The working principle of a DAC is the opposite of that of an ADC. A DAC can convert digital signals into analog signals for output and control. DACs have a wide … Read more
Introduction: Why the Choice of RTOS Can Be a Game Changer Choosing an RTOS (Real-Time Operating System) is one of the most strategic decisions in embedded product development. It determines how devices handle tasks, respond to events, and the reliability of cross-platform scalability. With the increasing diversity of connected devices (from low-power wearables to complex … Read more
