单片机程序设计（国外英文资料） Program design is the most important work, microcontroller development program design is using single chip microcomputer instruction system, according to the requirement of the application system (that is, the target product) write MCU application, in fact, we have already started to do before, this lesson we are not about how to design the specific application, but to teach you design the basic method of single chip microcomputer program. However, it is necessary to understand the programming language of the SCM before explaining it. A. The program design language here and we usually understand there is a difference between the language, it is designed for the development of single chip microcomputer programming language, if you havent learned programming may not understand, Ill give you a simple explain, you know that Microsoft VB, VC? VB, VC is designed for a certain engineering application of computer programming language, generally speaking, it is a design tool, but this tool is used to design a computer program. To design a single chip, there is a tool for designing a single chip. There are basically three types of design language for a single chip. The machine language machine language that is fully machine-oriented is the language that can be directly identified and executed by a single chip. What can the computer recognize? We used to talk about the number 0 or 1, so the machine language is the number of 0 or 1. For example: MOV A, 40H; By machine language is 0100000, apparently, written in machine language for single chip microcomputer program is not very convenient, is also not good memory, we must find a way to better use of the language to write MCU program, so there will be a language that is designed for single chip microcomputer development: 2. Also called symbolic language, assembly language assembly language using mnemonics to replace the binary 0 and 1, such as: just MOV A, 40 h is the assembly language instructions, clea
