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.

写汇编代码实现一个圆形的先入先出（FIFO）缓冲器…
To write assembly code to implement a circular First In First Out (FIFO) buffer in the data memory of PIC18F452 microcontroller, using the microcontroller’s direct addressing mode and indirect addressing mode. To expand on the FIFO assignment and implement the FIFO solution on the QWIKFLASH PIC target board and display the FIFOSTATUS as LED indicators. Recall:
Flags within a file register called FIFOSTATUS:
• Bit 0: FIFO_full
• Bit 1: FIFO_empty
• Bit 2: attempt_2_read when FIFO_empty
• Bit 3: attempt_2_write when FIFO_full

ST套件上0
ST套件上0-99秒计时，比较准的！(由网友wonderfulsf提供)
ST套件上0-99秒计时，比较准的！
这是我学习PIC完成的第一个程序烧在了ST套件上不错,0-99秒计时
如果用MPLAB模拟,用stopwach计时非常准
ST套件上0-99秒表程序,根据原0-99键控程序上改写的,初学练习-ST package on time 0-99 seconds, more accurate! (Wonderfulsf provided by users) ST package on time 0-99 seconds, more accurate! This is my PIC study completed the first procedure to burn in the ST package on good ,0-99 seconds time if MPLAB simulation, with very stopwach time on quasi-ST Suite 0-99 stopwatch program, according to the original 0-99 keying procedures on rewriting, and learning exercises
