how programming work? can we demostrate?

[lcs81]

AS i know, let say if we write a program in HLL(high level language) such as C, it can be compile to machine code.

This machine code is unique for different model of machine(or preciesly, processor or controller).

My question is, how can this "program" (software) make the machine work? How can we link this? Anyone can suggest a simple software programming to control a simple LED hardware whitout using any microcontroller or processor?

Is my suggestion possible?

You have to ask : how can this machine code make processor work?

How can we link this?

What do you mean?

a simple software programming to control a simple LED hardware whitout using any microcontroller or processor?

without using any microcontroller or processor? The software controling...?

--->yes, excatly what u understant

i mean--->How the machine code link to the hardware, or how the machine code control the hardware

I mean-->Can we create a circuit board, let say have 10 led and 5 switch(manual or electronic) and put in this machine code and program it as we wish?

There is a program for simulation of microprocessor software called Proteus:

You can use it to se how your code interact with simulated hardware in real-time.

You have to read
Central processing unit From Wikipedia, and take special attention on CPU operation section

You can't do that, except your build your own CPU on that board
