Embedded Learning Day 2

Embedded Learning Day 2

The Cortex-M3 processor features general-purpose registers R0-R15 along with several special function registers. Registers R0-R12 are 32-bit general-purpose registers used for data operations. However, most 16-bit Thumb instructions can only use R0-R7 (the low register group), while 32-bit Thumb-2 instructions can access all general-purpose registers. The special function registers have predefined functions and must be … Read more

C Language: Bit Manipulation and Registers

C Language: Bit Manipulation and Registers

Bit Manipulation Operators The bit manipulation operators in C language include bitwise AND (&), bitwise OR (|), bitwise XOR (^), bitwise NOT (~), left shift (<<), and right shift (>>). Bitwise AND (&): The result bit is 1 only when both corresponding binary bits of the operands are 1; otherwise, it is 0. For example, … Read more

How Do Computers Recognize Code? Starting from Assembly Language

How Do Computers Recognize Code? Starting from Assembly Language

▼For more exciting recommendations, please follow us▼ Learning programming is essentially learning high-level languages, which are computer languages designed for humans. However, computers do not understand high-level languages; they must be converted into binary code through a compiler to run. Knowing a high-level language does not equate to understanding the actual execution steps of a … Read more
