近年来,随着单片机技术的迅速发展,应用领域不断扩大,单片机在智能显示方面的开发与应用也日益为人们所重视。本文基于 MCS-51系列单片机中的8031研制了一种连接单片机和 CRT 显示终端的控制器接口板。这种接口板能够根据单片机的指令,输出 CRT 显示器所需要的全电视信号,直接与 CRT 连接;如经射频调制器调制,也可与普通家用电视机相连。CRT 接口板的特点:a.采用总线结构,直接与 MCS-51单片机连接,也可与其它8位 CPU (如8035、Z80、6052等)配套使用;b.在屏幕上可直接显示字母、字符、图形
In recent years, with the rapid development of SCM technology, the application fields are constantly expanding. The development and application of SCM in smart display are also increasingly valued by people. This text is based on 8031 in MCS-51 series one-chip computer to develop a kind of controller interface board that connects one-chip computer and CRT display terminal. This interface board can output the full TV signal required by the CRT display according to the instructions of the single chip and connect directly with the CRT. If it is modulated by a radio frequency modulator, it can also be connected with an ordinary home TV. CRT interface board features: a. The bus structure, directly connected with the MCS-51 microcontroller, but also with other 8-bit CPU (such as 8035, Z80, 6052, etc.) supporting the use; b. On the screen can be directly displayed letters, characters , Graphics
