Introduction Sharing an article I wrote previously. Recently, due to a price war between two PCB manufacturers, prices dropped multiple times in a single day, which was quite lively. Jiepei dropped to a minimum of 3 yuan per unit, while Jialichuang dropped to a minimum of 5 yuan per unit, both with free shipping via … Read more
Background: There are many methods to flash firmware on STM32. This article discusses the DFU method. Sometimes, due to certain software errors, JLink or STLink may fail to connect, and at this point, DFU can be used as a backup. There are many methods available online for using DfuSe on Windows, but this article mainly … Read more
When debugging microcontroller programs, serial printing is a common method. Sometimes, when the hardware does not reserve a serial port, other methods are needed for printing and debugging.1. Jlink SEGGER RTTJlink SEGGER RTT is a very useful method that allows you to achieve printf-like functionality simply by using the SWD or JTAG interface of Jlink, … Read more

Today, while using MDK to program, a warning appeared. Initially, I didn’t pay attention to this issue because during actual testing, the program could be programmed normally and also debugged. However, later a colleague encountered this warning repeatedly during debugging, which affected normal testing, so I decided to investigate! 01 Error Phenomenon The error message … Read more
Introduction This article introduces how to use JFlash to read the microcontroller’s program. Learning to read microcontroller program files is not intended for cracking someone else’s program but to understand the principles of cracking, thus better protecting your own program from being cracked. I hope everyone can respect others’ labor results. Downloading and Installing JFlash … Read more
Overview The author has always had an idea to create a powerful desktop tool that integrates various tools needed for development, such as: serial port assistant, network assistant, download tools, etc. However, this raises several questions: Question 1: How to present it on the desktop is also a very important issue — desktop floating window. … Read more
Click on “Gua Gua Little Master” above, select “Pin/Star Official Account“ Useful Resources Delivered First Hand! Summary: I wonder how everyone prints debugging information during microcontroller development. Most likely, they use serial debugging to print. In most cases, serial port 1 is usually reserved for debugging printing during board manufacturing and coding. But what if … Read more
