Many quantities in reality are analog, such as temperature and pressure. For a microcontroller to understand them, it must first digitize these quantities. AD conversion is the process of converting an analog signal into a digital signal. The AD chip introduced in this book is the ADC0804, an 8-bit parallel AD conversion chip. I won’t … Read more
An oscilloscope is a window to observe waveforms, allowing designers or maintenance personnel to see electronic waveforms in detail, achieving a real-time visual effect. Because the human eye is the most sensitive visual organ, it can perceive minute details and quickly reflect objects to the brain for comparison and judgment. According to the different classifications … Read more
Learning to use microcontrollers involves understanding the hardware structure of the microcontroller and the application of its internal resources, as well as learning various initialization settings for functions in assembly or C language, and programming to implement various functionalities. Here are some of my experiences: Step 1: Using Digital I/O Using button inputs to signal, … Read more
Click the blue text to follow us 1. Microcontroller Measurement and Control System and Analog Input Channel 1. Overview of Microcontroller Measurement and Control System Measurement and control include two processes: “measurement” and “control”. The so-called “measurement” is the real-time collection of physical parameters of the controlled object, such as temperature, pressure, flow rate, speed, … Read more
