Recently, I encountered a problem with byte endian conversion in a protocol, so I lazily went online to check it out and came across a similar issue, learning a new term called butterfly swapping. The Problem Is As Follows The protocol requires that the low byte is on the left and the high byte is … Read more
1. Embedding Assembly Language in C In microcontroller development, we usually write the main program in C language, which allows us to fully utilize the mathematical libraries and powerful data processing capabilities provided by C language tools. However, the controllability of C language is not as good as that of assembly language. For some time-sensitive … Read more

Abstract: I heard that many friends learning microcontrollers can’t use structs? Pointers and structs are essential to mastering microcontrollers. If your C language skills are shaky, you won’t grasp the essence of microcontrollers and will only complete some basic projects. Understanding structs and being able to use them flexibly indicates that you have entered the … Read more

The serial port is a commonly used interface in computers, with the most common being the RS-232-C interface. It was established in 1970 by the Electronic Industries Alliance (EIA) in collaboration with Bell Systems, modem manufacturers, and computer terminal manufacturers as a standard for serial communication. Its full name is “serial binary data exchange interface … Read more

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
GPIO, translated as General Purpose Input Output. I believe everyone is quite clear about the meaning of input and output. The most commonly used output function is the LED, while the most commonly used input function is the key. To use the GPIO functionality of STM32, the first thing to clarify is who controls this … Read more
