The STM32 microcontroller, based on the ARM Cortex-M3 architecture, has a complex and efficient internal bus structure that supports the entire system’s data flow and instruction execution, making it a key learning point for many embedded engineers. Below, we will list the main internal buses of the STM32 microcontroller and their functions. 1. I-Code Bus … Read more
This is a very practical share that not only introduces the project’s functions but also provides reasons for doing so. At the end, it offers learning suggestions for everyone. 01 Project Introduction The prototype of this project was my undergraduate graduation project, built from scratch, including hardware schematics, PCB, component soldering, lower machine programming, upper … Read more
Simplified method for using JLINK to download programs to STM32 via JTAG interface (SW and JTAG modes)! Anyone who has used STM32 knows that there are two common methods for downloading programs: via serial port and JLINK. The serial port download method is quite similar to that of the 51, so I won’t elaborate on … Read more
Recently, I was working on a motor drive application using the BGI MCU, and during debugging, I was plagued by a randomly occurring HARD FAULT. The issue was strange; the time it took to enter HARD FAULT was unpredictable. It could be triggered just a few seconds after connecting to USB, or it could take … Read more
This article is suitable for students who have studied LCD displays but do not fully understand them. The author uses the battleship STM32. In this article, the author will discuss three topics: FSMC-related configuration, principles of displaying a string of characters, and principles of displaying Chinese characters. Let’s get to the point →_→ 1. FSMC-related … Read more
Every hardware engineer learning embedded systems should have DIYed an oscilloscope at least once, not only because this process allows you to truly touch the soul of embedded systems, but also to deeply understand the core concepts of testing and measurement – after all, when you personally collect waveforms, display them, and measure parameters, the … Read more
There are currently three methods to program STM32: JLink, ULink, and Serial Programming, using tools such as JLink, ULink, and USB to TTL cable. ULink Programming During the installation of MDK, there will be a prompt to install the driver, which is the ULink driver. If you choose ‘Yes’, you do not need to install … Read more
