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
Assembly Language, for those who have never delved deeply into it, can be incredibly arcane. Since our computers are developed based on assembly language, understanding this content will greatly help us clarify how the CPU works. The X86 computer is fully backward compatible with the IBM PC – from the top level of the system … Read more
