液压计算（Hydraulic calculation） The basic process of MCU learning SCM enthusiasts often ask us, how to learn microcontroller? What is the procedure of learning SCM? We briefly sum up, microcontroller learning process can basically be divided into four stages: The first stage is to browse the hardware part of the textbook first, so as to understand the hardware structure of the scm. as ROM, RAM, address, I / O port, and see some manufacturers MCU data (Data Sheet) to come Reinforce the impression that MCU provides resources. The second stage is to understand binary numbers, sixteen digit numbers, and software. Although there are many High level language can be used for single chip programming, but I think the beginner or assembly language as well, more conducive to and Hardware combination, master the hardware structure. Knowing assembly language, machine language, instruction, program, etc, Start with the MOV instruction, and learn assembly language and programming, as in the 51 MCU assembly language system 111 instructions, simple and good understanding, how they relate to the hardware, and more conducive to the general learning microcontroller The integration and use of instructions. Therefore, you can first learn a few basic MOV instructions and their machine language, Roughly establish the hardware and software concept of SCM, to know that SCM hardware is controlled by instructions. The third phase, according to the manual of the programming environment, is familiar with the use of programming environment. The programming environment is now common Computer connected, as long as people with basic computer knowledge can quickly master the operation steps. The fourth stage is to rely on the experimental board, learning to master SCM assembly language, instruction systems and simple programming. At the same time and the previous knowledge of hardware combined with the assembly, to play the main learning software, and consolidate the dual role of hardware. At the beginni
