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
A microcontroller is a type of programmable controller that, after setting up the hardware circuit, can use programs to implement many very complex logical functions. Compared to pure hardware circuits, it simplifies the design of hardware peripherals, facilitates logical design, and enriches logical outputs. Different manufacturers of microcontrollers require different programming IDEs to achieve programming. … Read more
1. Introduction In electronic circuit design, there might be a situation where the microcontroller has no DAC resources and no spare PWM ports available. The only remaining option is a UART. So how can we output an analog voltage through this port? By using the microcontroller’s port, we can output a square wave signal with … Read more
In the field of microcontroller programming, it is crucial for developers to choose the right development tools. Choosing the wrong one may significantly reduce learning efficiency and make it harder to explore microcontrollers. Below, we will review several common programming software for microcontrollers, hoping to help everyone. 1. Keil Advantages: As an essential tool for … Read more
Word Count: 6000 Content Quality Index: ⭐⭐⭐⭐⭐ Abstract: Have you ever wondered where the functions and variables you write in Keil for microcontrollers end up? We often talk about the five areas of memory, but what exactly are those five areas? Where are they located on the chip? And why is it that after learning … Read more
Introduction Microcontrollers are quite “low-level” and “hardware” components, lacking complex data structures and intricate programming algorithms. We only need to understand and program from the perspective of how the microcontroller executes. For the average person, there is no need to delve deeply into the subject, as most of us are merely users of microcontrollers, not … Read more
In embedded system design, microcontrollers serve as the core controller and are one of the key learning topics for many engineers. However, there are a wide variety of microcontrollers on the market with different functions. Today, this article will compare several of the most common types of microcontrollers, hoping to help everyone. 1. 51 Microcontroller … Read more
This article aims to validate the usage of the STM32 SPI interface using the W25Q16 storage chip. ●About Flash Chips 1. When writing to flash, it can only change from 1 to 0; during erasure, all bits become 1. 2. The minimum write unit for flash is a page; individual bytes cannot be written. 3. … Read more
Introduction Since both the Arduino controlling the lead screw and the board controlling the servo only have one UART, they need to communicate with each other, and also with the Raspberry Pi. Therefore, the number of UARTs is insufficient. Thus, I created a UART Data Manager using the STM32F103 chip, which has three UARTs: USART1~3. … Read more
0 Preface The previous article introduced how to use STM32CubeIDE to create a new project and its features. This article will continue to explain how to configure the project, which is also a very important step. 1 Introduction to the Configuration Interface (STM32CubeMX Interface) The project configuration is mainly operated through the original STM32CubeMX tool. … Read more
