Comparing Programming Methods of 51 and STM32 Microcontrollers

STM32 and 51 microcontrollers are two common series of microcontrollers, which differ in hardware architecture, performance characteristics, and programming methods. However, from the perspective of C language programming, I believe they are quite similar. Let’s compare their programming characteristics:

Comparing Programming Methods of 51 and STM32 Microcontrollers

STM32: STM32 is a 32-bit microcontroller based on the ARM Cortex-M core, featuring strong processing capabilities and rich peripheral functions. It adopts a modern internal memory structure and peripheral interfaces, supporting various communication interfaces and advanced functional modules.
51 Microcontroller: The 51 microcontroller is an 8-bit microcontroller based on the Intel 8051 core, with a relatively simple hardware architecture and functional characteristics. Its processing capability and peripheral functions are relatively weak, suitable for simple control applications.

STM32: The main programming languages for STM32 are C/C++, and it also supports assembly language programming. Typically, integrated development environments like Keil and IAR are used for programming development.
51 Microcontroller: The main programming language for the 51 microcontroller is assembly language, but it also supports C language programming. Due to its lower storage capacity and processing capability, assembly language is more commonly used in 51 microcontroller programming.

STM32: STM32 peripheral drivers usually use the Standard Peripheral Library or HAL (Hardware Abstraction Layer). Developers can choose the appropriate library for peripheral driver development based on their needs.
51 Microcontroller:: The peripheral drivers for the 51 microcontroller usually require manual coding of the corresponding register operation code, which is relatively cumbersome and low-level.

Since STM32 is a 32-bit microcontroller with strong processing capabilities and rich peripheral functions, programming is relatively more complex, but it also offers more functionalities and flexibility. In contrast, the 51 microcontroller is an 8-bit microcontroller, which is simpler to program but has limited functionality and performance.
