一、概述单板机是厂家提供的一种通用微机系统,使用者只要根据应用要求配以专用的I/O接口电路,编制应用软件,即组成以单板机为核心的微机化装置。这种研制方法大大地减轻硬件设计的工作量,有益于微机应用的推广。随着微机广泛应用于工程科技各个领域,提高产品竟争能力,产品微机化的要求也越来越高。微机化产品要求设计满足各种专用目的的最小微机系统,其理由如下:
First, an overview Single board machine is a general-purpose microcomputer system provided by the manufacturer, the user as long as the application requirements accompanied by a dedicated I / O interface circuit, the preparation of application software, that is composed of a single-chip microcomputer as the core of the device. This method of development greatly reduces the workload of hardware design, useful for the promotion of microcomputer applications. As the microcomputer is widely used in all fields of engineering and technology to improve the competitiveness of products, products, computer-based requirements are getting higher and higher. Microcomputer-based products require the design of the smallest microcomputer system designed to meet a variety of specialized purposes for the following reasons:
