1. What are the advantages and disadvantages of C language and assembly language in microcontroller development? Answer: Assembly language is a symbolic language that uses mnemonic words to represent machine instructions, making it the closest language to machine code. Its main advantages are low resource usage and high execution efficiency. However, assembly languages may differ … Read more
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: 51 & STM32 STM32: STM32 is a 32-bit microcontroller based on the ARM Cortex-M core, featuring … Read more
During the process of writing this 8*8 key program, whether I was writing it myself or referencing others’ programs, I found that I had many misunderstandings about some basic points of C language and programming norms. Some were due to my previous bad programming habits, and some were a manifestation of not having a solid … Read more
Introduction A microcontroller, also known as a microcontroller unit (MCU), integrates a complete computer system, including the CPU, RAM, ROM, timers/counters, and various I/O interfaces, onto a single chip. Due to its numerous advantages and characteristics, the applications of microcontrollers are extremely wide-ranging. A microcontroller system consists of both hardware and software systems, which involves … Read more
