In computer science, there are various ways to represent numbers. In addition to the binary and decimal systems we discussed earlier, the octal system is also a common numeral system. The octal system is base 8, using the digits 0 to 7 to represent all numbers. Although octal is not as widely used in daily … Read more
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
