UART, or Universal Asynchronous Receiver/Transmitter, is one of the most commonly used communication protocols between devices. When configured correctly, UART can work with many different types of serial protocols that involve sending and receiving serial data. In serial communication, data is transmitted bit by bit over a single line or wire. In bidirectional communication, we … Read more
1. What is the Validity of IIC Protocol Data? (1) Data Transmission Format Start and Stop Conditions: When the SCL line is high, a transition from high to low on the SDA line indicates a start condition; when SCL is high, a transition from low to high on the SDA line indicates a stop condition. … Read more

0 Introduction Before discussing Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC), let’s first clarify what analog signals and digital signals are. Analog signals can be understood as physical quantities from the real world, but these quantities are electrical signals. For example, radio signals, etc. The characteristics of analog signals are that … Read more
To acquire information from the external environment, humans must rely on sensory organs. However, relying solely on human sensory organs is inadequate for studying the laws of natural phenomena and production activities. To adapt to this situation, sensors are required. Therefore, it can be said that sensors are an extension of human senses, also known … Read more
