1. Introduction In the development of STM32 microcontrollers, using SWD for program downloading only requires two pins. So, when do we need to use the microcontroller’s RST port? This involves the pin configuration of the microcontroller. In the CubeMX software configuration, there are five options regarding system debugging settings. If you choose SWD debugging, you … Read more
Operating System: Windows (MinGW or MinGW-w64) / Linux / macOS Required Tools: Debug probe with software, cross-compiler toolchain Build Targets: CMake / Makefile / Custom build targets To debug on the chip, you need to create a special run/debug configuration. In CLion, you can quickly create the following GDB server configurations using the "New Embedded … Read more
Word Count: 2000 Practicality Index: ⭐⭐⭐⭐⭐ 01 Macro Print Function In our embedded development, using printf to print some information is a common debugging method. However, when the amount of printed information is large, it can be difficult to know which information is printed in which function. Especially for printing exceptions, we need to quickly … Read more
To understand which software is commonly used in the electronics engineering field, we first need to look at some of the relevant technologies and industry applications. Electronics engineering, also known as “low voltage technology” or “information technology”, can be categorized roughly as shown in the figure. The applications of electronics engineering cover electric devices, as … Read more
Operating System: Windows (MinGW) / Linux Project Format: CMake When setting up a toolchain for your embedded project, you can use the IAR compiler. CLion recognizes it as a C/C++ compiler and collects compiler information. You can also open projects that use the IAR toolchain, which should load successfully. Currently, only CMake-based projects are supported. … Read more
Header File Meanings avr_macros.h includes simplified writing for reading and writing 16-bit registers, along with several bit manipulation functions. comp_a90.h provides brief writing for a large number of intrinsic functions. ina90.h includes the “inavr.h” and “comp_A90.h” files. intrinsics.h provides intrinsic functions that offer the simplest operations for handling the processor’s low-level features: sleep, watchdog, FLASH … Read more
Recently, my supervisor asked me to modify the program for the AT89C52. The code written by the previous developer is truly unworthy of praise. Have you ever seen a program with over 10,000 lines in a single .c file? This is one of them. It has an extraordinarily large while loop and four layers of … Read more
When I first installed KEIL5 on my computer, I didn’t encounter any issues. However, a few days ago, my C drive got corrupted, and after reinstalling the system, I faced problems while installing KEIL5 again. After the normal installation of KEIL5, I started the PACK installation, but it kept failing. At that time, I was … Read more
In-depth analysis of Keil C51 bus peripheral operation issues. 1 Problem Review and Analysis In actual work, encountering repeated consecutive reads of the same port, the Keil C51 compiler did not achieve the expected results. Analyzing the assembly program generated by the C compiler found that the second read statement of the same port was … Read more
