WIN98硬盘引导记录祥解

AT89S51的并行口P1接4×4矩阵键盘，以P1.0－P1.3作输入线，以P1.4－P1.7作输出线；在数码管上显示每个按键的“0－F”序号。-AT89S51 the parallel port P1 then 4 × 4 matrix keyboard to P1.0-P1.3 as input lines to P1.4-P1.7 for output line in the digital control button displayed on each of the " 0-F" serial number.

可编程并行接口 8255可编程并行接口。 利用高端的输入 哦也，玩的不是ASM是寂寞-no

用win32汇编语言写的一个万年历小程序-Win32 written in assembly language using a calendar applet

首先，分别对8255、8253进行初始化，设置8255为A口、C口输出，设置8253的计数器0为工作模式3；其次，设置IRQ7的中断矢量，使得有IRQ7中断时调用SERVER；再次，调用INIT对计数值初始化；最后，主程序循环等待中断，开始秒表的计时。 2、 INIT子程序-First, the 8255,8253 initialization, set for the 8255 A-C mouth output, set 8253 as the Counter mode 0 3; Second, set up the interruption vector there, make it there interruption call SERVER; Again, call curl_setopt early to count before; Finally, the cycle of waiting for the main program interruption began stopwatch time. 2, curl_setopt Subroutine
