C Language Pointer Concept Lecture and Hands-On Seminar for MCU Control!

There are many types of computer languages around us. However, only C language can control all Processors. This is why we create Processors needed for home appliances, automobiles, and so on through C language.

What are the powerful characteristics that C language possesses?
It is pointer arithmetic. So what is pointer arithmetic?

Just as when sending a letter to someone, you write an address number on the envelope, all components inside a Processor are distinguished by address numbers. The process of storing these address numbers and performing arithmetic operations on address values is called pointer arithmetic.

Following the previous lecture, this session is designed for those learning the fundamentals of C language and processors. We will study the pointer concept, which is the most important in C language.

Practical Example: Step-by-step explanation of how address numbers are used in the process of LED blinking through GPIO port using CodeMania




C language can directly allow the Core to access arbitrary peripheral devices it wants to reach through address numbers.

In other words, when looking at the inside of a Processor, it is composed of a Core that interprets instructions and peripheral devices that perform operations according to the Core's commands.
At this time, for the Core to command each peripheral device—for example, a peripheral device connected to an external temperature sensor—to read the current temperature value, the Controller of that peripheral device must be controllable.
Here, controlling a Controller ultimately means setting new values in the Registers that compose the Controller, and it is the address number that is used to identify these Registers.

Therefore, the reason the Core can set new values in a specific Register of a Controller connected to a temperature sensor among many peripheral devices is because it can access the unique, that is, the exclusive address number that the Register possesses.
