When we first learn embedded development, a common question arises: what is the difference between C language and embedded C programming? Embedded engineers typically tell you that the difference lies in the fact that embedded C runs on embedded development boards, which differ from CPUs in computers, leading to different compilers and executable programs. Unlike … Read more
Previously, we discussed why microcontrollers should be programmed in C language and what programming environments are required. Today, we will introduce the basic knowledge of microcontroller programming. First, we need to introduce bitwise operations. Bitwise operations are very common when configuring microcontroller registers. For instance, when configuring the GPIO of a microcontroller to output direction … Read more
With the development of technology, electronic products are becoming more and more common, making our daily lives more convenient. Most electronic products have microcontrollers, which achieve functionality by executing software logic. While assembly language is the most suitable programming language for microcontroller programming, the most commonly used and widespread is C language. So, why should … Read more
Continuing to post my answer. First, you need a development board. If you are just starting in the field of microcontrollers, I recommend starting with videos. At the very least, you should have a book on C programming for reference on C language concepts. When you first start learning, focus on videos. For concepts that … Read more
This issue’s topic: As is well known, in C language, dividing a number by 0 will lead to a division operation exception, causing the program to crash. To avoid program crashes, we need to include checks for 0 in the code. However, when running C program code that performs division by zero on STM32 microcontrollers, … Read more
Selected from GitHub Author: Zoltan Baldaszti Compiled by: Machine Heart Editor: Chen Ping The Raspberry Pi, though small—only the size of a credit card—functions just like a regular computer, capable of connecting to TVs, monitors, keyboards, and mice. It can handle text, spreadsheets, media, and even games. So how can this magical little computer be … Read more
