单片机模拟器Virtual51

Virtual51是一个动态可视化的MCS-51全功能模拟程序，可以让你在Virtual51上运行MCS-51程序就如同在硬体上一 样。提供8KB的程序空间，256字节的RAM，16KB的XRAM，2个16位的定时/计数器（T0 和 T1），一个实时时钟，一个 5X6的小键盘，一个128X64点阵的LCD，一个音频发生器，一个串口（未连接至电脑串口），一个打印口（连接至电脑 打印口），和5个有两个优先级的中断源。 Virtual51不可以载入大于8KB的51程序和大于16KB的XRAM数据文件，并且程序以固定的12Mhz时钟运行，编写程序时留意。 XRAM载入数据文件的实际大小，可从XRAMSH 和 XRAMSL 寄存器中读取。 例子说明： KeyPad---------简单演示KeyPad的使用； Music----------Virtual51演奏音乐； Picture--------LCD图形演示； Proc24c02------使用Virtual51从电脑打印口读写24C02A 运行环境： WINDOWS ME/2000/XP 特别声明： 此程序的提供仅方便于学习，请不要用于其他用途，由此而带来的损失，概不负责。 您可以复制，散发此程序，但不得修改此程序，亦不可将此程序用于商业用途。本人保留一切权利！
