The noinit section is familiar to most of us developers working with microcontrollers. If this section is used, it will be automatically allocated by the compiler to a region in the chip’s SRAM (note that it is in the RAM area, not Flash). Variables defined in this section will not be re-initialized during any chip … 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

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
The default integer constant operations in the C51 compiler may lead to overflow errors. To avoid potential calculation errors, the data type of large integers should be specified. Keil C51 is a compiler compatible with ANSI C. The ANSI C standard specifies that the default data types for decimal integer constants are one of int, … 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
Recently, I have encountered the issue of Chinese garbled text in the compiler. Although it does not affect the execution of the program, it always feels awkward to see a bunch of garbled text. I have a bit of OCD and always want to fix it! The reason for this problem is that everyone uses … Read more
An error occurred: FATAL ERROR L210: I/O ERROR ON INPUT FILE: EXCEPTION 0021H: PATH OR FILE NOT FOUND. Later I found out that it was due to insufficient MCU memory. After some investigation, I discovered that my KEIL was not cracked, which prevented compilation of programs larger than 2K. After cracking KEIL 2 again, loading … Read more
