Biomechanics of Spinal Deformities For progressive deformities, the spine is subjected to some form of “pathological” stress. Spinal surgeons need to understand the source of this “pathological” stress that causes the deformity. Only when these “pathological” stresses are counteracted and neutralized can the goals of correcting scoliosis, preventing deformity progression, and restoring sagittal and coronal … Read more
I have been thinking about this content for a long time, but either I got busy or my writing skills were off, so I never got around to it. Today, I’ll finally share it; otherwise, it would be buried deep in my brain. Haha. The content is quite simple; it’s just about setting up the … Read more
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
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
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
