基于asm汇编语言实现的是在pc系统中int9中断功能的部分示例,只在说明机制,进行学习,不能实际应用...

与中断矢量设置与读取有关的DOS功能调用，本例演示了如何编写中断服务程序，如何安装（将中断服务程序的地址设置到中断矢表中），以及如何通过软中断指令调用中断服务程序。为了突出重点，本例中中断服务程序代码未驻留内存。-and vector interrupt settings and read the DOS function calls, which in this case demonstrated how to prepare interrupted service procedures, how to install (to be interrupted service procedures set up to address the interruption vector table), and how soft interrupt directive calling service interruption program. To highlight key issues, in this case the interruption of services not the presence of code memory.

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

这是一个学生成绩管理系统，有部分功能还不完善，以后会慢慢更新的：）-This is a performance management system for students, some function is not perfect, the future will gradually updated :)

电动车从起跑线出发（车体不得超过起跑线），沿引导线到达B点。在“直道区”铺设的白纸下沿引导线埋有1~3块宽度为15cm、长度不等的薄铁片。电动车检测到薄铁片时需立即发出声光指示信息，并实时存储、显示在“直道区”检测到的薄铁片数目。 （2）电动车到达B点以后进入“弯道区”，沿圆弧引导线到达C点（也可脱离圆弧引导线到达C点）。C点下埋有边长为15cm的正方形薄铁片，要求电动车到达C点检测到薄铁片后在C点处停车5秒，停车期间发出断续的声光信息。 （3）电动车在光源的引导下，通过障碍区进入停车区并到达车库。电动车必须在两个障碍物之间通过且不得与其接触。 （4）电动车完成上述任务后应立即停车，但全程行驶时间不能大于90秒，行驶时间达到90秒时必须立即自动停车。 -err
