这是一个简单的进位制转换程序，它的功能是可以把任何进位制的数字转换成十进位制。...

一、 使用键盘显示接口芯片8279接收按键键值，并在七段数码管上显示出来，通过判断键值进入相应音乐播放处理程序。在音乐播放程序中，使用定时器/计数器8253的计数器2，使其工作在方式¬ ¬ 3―方波发生器，通过查表依次取出乐曲频率值送入计数器作为计数初值，经out2输出方波，驱动扬声器发出不同频率的声音，在每个音阶之间加入相应的延迟时间，即实现了音乐的播放。-First, the use of a keyboard display interface chip receive keys keys 8279, and Seven-Segment LED display, through to determine the corresponding music player keys to enter the treatment program. Procedures in the music player, use the timer/counter 2 counter 8253 to work in the way ? ? 3- square-wave generator, followed by out music through the look-up table values into the counter as a frequency count of the initial value, the output side out2 waves, driven loudspeakers of different frequency sound, in between each scale by adding the appropriate delay time, namely, the realization of the music player.

本程序是一个代有带纠错码的串行通信子程序 功能：发送方将数据连发三此，接受方按位进行最大概率纠错。程序返回时，若标志位ERR返回为1，则表示 通信失败；否则。接收结果放在A寄存器中。 很简单很经典的例子。有资源大家共享哦-This procedure is an error-correcting code generation has to bring the serial communication subroutine functions: sender data Lianfa three of this, the recipient in accordance with the maximum probability of bit error correction. Procedures for the return, if the flag ERR return for one, it means that communications failed otherwise. Receive the results on the A register. Very simple classic example. U.S. has resources to share, oh
