What's the difference between 5 1 MCU and STM32? Can a programming language also use assembly language?

1. The wider the data bus width, the faster the processing speed. 2. The assembly instruction set is different. 5 1 is the mcs5 1 instruction set, and stm32 is the arm instruction set. The content of instruction set is similar, but there is still a big gap in form. 3.5 1 is cheaper, more cost-effective and more knowledgeable. 4. Different simulation environments make different simulators. 5.5 1 There is no intellectual property problem, and the patent has expired. 6. The development speed is different. 5 1 Now follow, STM32 leads. Similarities: both assembly and C language are acceptable. It is suggested to learn the basic functions of single chip microcomputer, starting with lighting an LED, and then running lights, interrupts and other peripheral devices of single chip microcomputer. Practice the basic skills first, then you can climb higher.
