一、最小系统接口硬件(一)最小系统的含义最小系统在微机应用中,可理解为构成各种不同专用控制系统所需要的最小硬件配置。因此,在这种意义下没有一个绝对的最小系统,即构成最小专用系统的方法不是唯一的。在构成专用最小应用系统的同时,还需配套选用相应的输入输出接口板。(二)接口硬件在仪器仪表及设备的自动控制中,单片机的应用形式多为工作方式和命令的按键输入,测控过程中的状态信号与数字显示,以及测控结果的数据显示和打印输出等。
First, the smallest system interface hardware (A) the meaning of the smallest system Minimum system in computer applications, can be understood as constituting a variety of different dedicated control system required minimum hardware configuration. Therefore, in this sense there is no absolute minimum system, that is, the method that makes up the smallest private system is not unique. In the composition of a dedicated minimum system at the same time, also need to select the appropriate input and output interface board. (B) of the interface hardware In the automatic control of instrumentation and equipment, the application form of the microcontroller more for the work of the order and the key input, the process of monitoring and control status signals and digital display, as well as the results of measurement and control data display and print output.
