Introduction to MCU Programming

Introduction to MCU Programming
Recently, I found that many new students who have just graduated from the university are very confused about the preparation of the single-chip program. They do not know where to start and how to implement the desired functions. Although I have learned relevant courses in school, maybe the course design or graduation design is a small design of single chip microcomputer, but the circuit board and the program are basically done, the students just need to assemble, compile, and download them. This process is just a bit familiar with the environment, and the actual work requires brains. Obviously, this change needs to be adapted. How can we adapt? The school has already laid the foundation, and it requires confidence and correct steps. It is very realistic to get the code that can run on the single chip microcomputer from the Internet or the predecessors, download it to the target board, and learn about the functions of each part of the code, if you do not understand it, go to the next breakpoint for One-Step debugging. After getting familiar with the code components and the execution processes and functions of various parts, remove unnecessary ones a little bit and add and implement your own functions. If you encounter problems that are hard to understand and confused, contact du Niang, in combination with the experiment debugging, we can find a solution. At the beginning, we will certainly encounter many small problems. A small problem may be suffering for a week and there is no way to solve it. At this time, we must stick to it and think and solve it one by one, after you solve several problems, you will find that you are getting started. In fact, the focus is only one sentence: diligent use of breakpoint debugging and Du Niang. Low-speed and Digital Single-Chip Microcomputer circuits do not have much difficulty in design. The pattern is still in the software. A clear, concise, and functional structure design must be stable, reliable, easy to maintain, and highly scalable, A mess of Code together will inevitably cause errors and errors, making it difficult to upgrade and maintain. Single-Chip Microcomputer Software also requires an architecture. Embedded engineers tend to focus on the hardware. In the face of strange components, it is easy to get lost. The detailed design ignores the overall structure, and brought this habit to the software design, making the software structure unclear, and the details of the branch. Training Software thinking, deep understanding of modularity and object-oriented design ideas is an advanced Required Course for every embedded engineer.
