System Development Procedure

System development using a microcontroller can be divided into hardware development and software development.
In hardware development, the circuit diagram for the hardware part is designed according to the system specifications.
Based on the designed circuit diagram, the board is made and the parts are procured.

In software development, the specifications of the software part are designed according to the system specifications.
Coding is performed based on the specification design, and it is converted into machine language by compiling.

The hardware and software are then tested together.
This is also called a debug with a real machine.
At this time, an emulator, etc. are used.
And if there is no problem, the procedure would be to finish development, begin mass production, and then product shipment.
