The MCU chip refers to the Microcontroller Unit (Microcontroller Unit; MCU), also known as a microcontroller or single-chip microcomputer. It appropriately reduces the frequency and specifications of the central processing unit and integrates memory, counters, USB, A/D conversion, UART, PLC, DMA, and other peripheral interfaces, even the LCD driver circuit, into a single chip, forming … Read more
Introduction: This article introduces the MCU chips in four domains: body, chassis, power, and cockpit, from four dimensions: working requirements, performance requirements, industry landscape, and industry barriers. It also organizes the application status of domestic MCU chips for reference by practitioners. 1. Introduction to Control Chips The control chip mainly refers to the MCU (Microcontroller … Read more
Click the blue text to follow us 1. Overview of Microcontroller Programming Languages 1. Three commonly used programming languages for microcontrollers Machine Language Refers to programming directly using machine code, which can be executed directly by the computer. Assembly Language Refers to programming languages that use mnemonic codes to replace machine code. High-Level Language The … Read more
Abstract：We encounter many operating systems, such as Windows, Android, iOS, and Linux, which are all types of operating systems. Microcontrollers also have their own operating systems, known as real-time operating systems. So what are the differences between these real-time operating systems and the systems we use? The operating systems we commonly use are actually non-real-time … Read more
First, let us briefly introduce the specific functions of each pin of the 51 microcontroller, and then we will focus on the concept of the microcontroller minimal system, its composition, and the practical uses of the circuit diagrams of its various parts. According to the pin identification method of integrated circuits, with the notch facing … Read more
The 51 microcontroller has a long development history since its inception and is one of the oldest and most widely used microcontrollers. To become an excellent microcontroller engineer, mastering the technology of the 51 microcontroller is essential. Today, we will discuss the minimum system of the 51 microcontroller, namely the 8051/8751 and 8031. 1. What … Read more
Generally, ROM is used to store firmware, while RAM is used to hold data. Since FLASH ROM has faster read and write speeds and is easier to erase compared to ordinary ROM, it is typically used to store user programs and data that need to be permanently saved. For example, the core of a household … Read more
Those who play with microcontrollers must have heard of IAP, ICP, and ISP. Today, I will help everyone “consolidate” the relevant knowledge. ● ICP (In Circuit Programming) ● ISP (In System Programming) ● IAP (In Application Programming) 1. ICP (In Circuit Programming) Those who have used Nuvoton microcontrollers must know that Nuvoton provides a set … Read more
I have always been curious about a question: every time I finish writing a microcontroller program and use the burning software to upload it, I can see the size of the burning file, which is the hex file size: The microcontroller chip I am using is the STM32F103C8T6, which has a program memory (flash) of … 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
