資源簡介
Virtual51是一個動態可視化的MCS-51全功能模擬程序，可以讓你在Virtual51上運行MCS-51程序就如同在硬體上一
樣。提供8KB的程序空間，256字節的RAM，16KB的XRAM，2個16位的定時/計數器（T0 和 T1），一個實時時鐘，一個
5X6的小鍵盤，一個128X64點陣的LCD，一個音頻發生器，一個串口（未連接至電腦串口），一個打印口（連接至電腦
打印口），和5個有兩個優先級的中斷源。
Virtual51不可以載入大于8KB的51程序和大于16KB的XRAM數據文件，并且程序以固定的12Mhz時鐘運行，編寫程序時留意。
XRAM載入數據文件的實際大小，可從XRAMSH 和 XRAMSL 寄存器中讀取。
例子說明：
KeyPad---------簡單演示KeyPad的使用；
Music----------Virtual51演奏音樂；
Picture--------LCD圖形演示；
Proc24c02------使用Virtual51從電腦打印口讀寫24C02A
運行環境：
WINDOWS ME/2000/XP
