单摆实时仿真软件是利用混合语言编程方法实现的实时仿真软件，仿真算法是四阶龙格库塔法，定时器使用与PC兼容的8253中的0通道，实时主要利用了与PC兼容的主片8259A中IR0的日时钟中断，使用BC3.0进行混合语言编译，产生的代码存放路径必须有EGAVGA.BGI图形驱动程序，该程序具有简单的人机交互界面，适合研究生计算机仿真课程的教学使用。-Real-time simulation software is a simple pendulum using mixed-language programming to achieve real-time simulation software, simulation algorithm is fourth-order Runge-Kutta method, using the PC-compatible timer 8253 in the 0-channel, real-time mainly use the PC-compatible with the main 8259A chip clock in the day IR0 interrupt, the use of BC3.0 mixed language compiler to generate code that stored the path must have EGAVGA.BGI graphics drivers, the program has a simple interactive interface, suitable for post-graduate courses teaching the use of computer simulation .
