What is a microcontroller? How to program a microcontroller?
Usually, we are designing circuits and connecting them to other different components, such as motors, by providing the
power supply that the circuit uses, LCD，LED。 What does the microcontroller do when programming with this circuit?
The microcontroller series understands programs
written in assembly language or C language, which must be compiled into a machine language called binary language
(i.e. zero and one). The programmed files are stored in the computer”s hard drive or microcontroller”s memory. Assembly
programs are used to convert assembly programs into machine code. To write programs in assembly language, programmers
must have knowledge of CPU or hardware. Low level languages are used for cross development. The hexadecimal system is used
as a more efficient way to represent binary numbers, and when using binary language, the CPU”s working speed is very fast.
Today, we can use many different programming languages, such as C, JAVA, ORACLE, etc. These languages are called high-level
languages. Writing programs in high-level languages, programmers do not require any hardware knowledge for advanced application
development. The compiler plays a crucial role in transforming high-level programs into machine level ones, as high-level languages are used in native development.
