In the C language, you can use typedef to define an alias for existing types (including int, double, long, structures, etc.). The alias can be used to define variables just like standard type names. 01 — Usage Form The usage form of typedef is as follows:typedef standard type name alias;For example: typedef int IN; After … Read more
The C language is essential foundational knowledge in microcontroller development. This article lists some common basic knowledge of C language in STM32 learning. 01 Bit Manipulation Bit manipulation is different from bit-banding operations. Bit manipulation refers to performing operations on each bit of a variable, while logical bit operations are performed on the variable as … Read more
