这是一个dos下的时钟驻留程序-This is a dos clock presence under the procedures

学习单片机的教程往往是流水灯、数码管、键盘等等。这些例程主要是熟悉单片机的端口性质，程序算法一般都比较简单。极少见结合单片机I/O端口，内部存储器以及运算技巧为一体的综合性练习。超简单单片机学习套材中的16X16汉字点阵模块提供了一个全新的学习平台。在一块只能显示一个汉字的点阵中，只利用Atmega48的内部资源实现几个汉字的移动，不但要清楚点阵的物理性能，知道如何送数据；还要了解单片机的可用资源，并通过编程利用内部存储器移动交换数据，确实是需要些技-Microcontroller tutorial to learn is often water lights, digital control, keyboard and so on. These routines are mainly familiar with the nature of microcontroller port, the program algorithm is generally relatively simple. Rare combination of microcontroller I/O ports, the internal memory and computing skills integrated exercises. Super-simple MCU learning materials in the 16X16 set of Chinese characters dot-matrix module provides a new learning platform. Can only display one character at a dot-matrix, only the use of internal resources to achieve Atmega48 few characters of the movement, not only to clear the physical properties of dot-matrix, to know how to send data also understand the MCU resources available, and programmed to exchange data using internal m
