Some functions of the hardware can be implemented by software beginner microcontroller .

The circuitry in the microcontroller is not a solidified level conversion circuit.

The instruction (i.e., the program) is input to the single-chip microcomputer, and through the interpretation and execution of the internal circuit of the single-chip microcomputer, the result of the execution will be transmitted to different components according to the requirements of the instruction, and different effects will be produced.

The software of the single-chip microcomputer is built by the hardware circuit, if the instruction does not conform to the single-chip microcomputer (that is, incompatible), then the single-chip microcomputer cannot interpret and execute this instruction.

The operation of the hardware circuit of the single-chip microcomputer is controlled by software, if there is no software to control the operation of the hardware circuit, then the hardware circuit is like a computer without an operating system, and nothing will be done.

The single-chip microcomputer is to do the logic control, the internal gate circuit conversion of the single-chip microcomputer is to do the analog circuit conditioning, you need to realize the level conversion (logic transformation) you need to use software instructions, the internal hardware gate circuit must be more than one, is a combination of many gate circuits, you don't have to worry about these, as long as you program it according to the operation method of the single-chip microcomputer.

There must be a bridge between hardware and hardware to communicate with each other, and to connect, there must be a software to communicate between them, and this software is just like our real life, there must be a law to restrict, otherwise they will do their own thing, then it will not be messed up?

Probably you've heard the term bare metal, a microcontroller without software doesn't make sense, it doesn't do anything. Such as walking with the dead (analogy is inappropriate).There is no soul.

After writing the software, there is a thought, and with the thought, the hardware can be coordinated to work in an orderly manner!

Specific problems are analyzed in detail!

Tell us about the specific problem examples, and it's best to post the software as well! Don't be subjective!!

1. MCU software refers to the ROM in the single-chip microcomputer with its own solidification boot program, or the user writes into the ROM or RAM heavy program.

2. The hardware of the single-chip microcomputer refers to: such as its own 4 parallel ports, timer counters, serial communication, internal special registers, etc.

Hardware is what you can see, hard drives, monitors, memory. and other material things.

Software is information, programs, and other things.

Just like a book, paper, ink, staple lines, etc. are hardware, and the content expressed in the text of the book is software.

Answer dear, hello! A computer system consists of two parts: "hardware" and "software". The so-called "hardware" refers to the physical part of the computer, which is composed of various electronic components that can be seen and touched, and various kinds of optical, electrical, and mechanical equipment, such as hosts and external equipment.

The so-called "software", which cannot be seen or touched, is composed of programs with various special functions that people have programmed in advance. These programs are usually stored in a variety of ** (RAM, ROM, tape, disk, CD, or even paper tape, etc.), and they are usually stored in the computer's main or secondary memory.

Now it also refers to a job in general, where external and internal conditions are combined. It's about equipment and services to keep up.

Software refers to bootstrapping, programs, etc.; Hardware refers to entities such as chips, circuits, etc.
