Description: 打字游戏设计
采用DOS功能调用（INT21H）中的AH=2CH得到系统时间，系统时间除模26得随机数，在此基础上加上基准字母，就可以得到随机字母。再利用BIOS功能调用中的INT10H AH=02H、06H、09H、0AH就可以控制字母的下降及判断字母的正确与否。利用8253的方式2进行计时和8259A中断就可以控制每10分钟打印，而打印则采用并行接口芯片8255A与中断芯片8259A以中断方式打印。-Typing game design using DOS function calls (INT21H) in the AH = 2CH get the system time, system time, except for 26 were random numbers, on this basis, with reference letters, it can be random letters. Re-use BIOS function calls in the INT10H AH = 02H, 06H, 09H, 0AH can control the decline in the letters and the letters to judge right or not. The use of 8253 means 2 for timing and 8259A interrupt can control every 10 minutes to print, while the print is applied parallel interface chip 8255A and 8259A interrupt chip to interrupt printing.

Description: 通过按动STAR ES598PCI单板机的G6区的1~7号键，使用单板机上的8255A芯片进行音调的选择，由8253芯片控制产生不同频率的方波，输出到单板机上D1区的蜂鸣器，使其对应于G6区的1~7号键由低到高发出1~7的音阶，并由8255A芯片控制8253芯片的工作状态，使其能够控制蜂鸣器的发声与否，从而实现简易电子琴的演奏功能。同时，也可以通过事先设置好的“乐谱”回放一段音乐，实现简易电子琴的回放功能以及对用户演奏过的一段音乐进行重放功能。用户可以通过DOS界面下的菜单对电子琴的回放和重放或是演奏功能进行选择。-Through the press ES598PCI single trigger G6 STAR of the 1 ~ 7 keys, use on veneer 8255A chips for the choice of 8253 tones and different frequency of chip control, to the output pulse on veneer, making it the buzzer D1 G6 corresponding to the 1 ~ 7 keys from low to high send 1-7, and the scale of 8255A chip control 8253 chips working condition, which can control the buzzer voice or not, so as to realize the function of simple keyboard playing. At the same time, also can be set through the music playback period, the simple keyboard function and user to play music played on a replay function. Users can pass on the menu under DOS interface and replay the replay keyboards or play function.

Description: 根据乐曲中不同的音符是由输出不同频率的声波而产生的原理，通过设置PC机中 8253定时器不同的计数值，可由扬声器发出不同的曲调。 以下是实现PC机作为一架可弹奏的钢琴演奏预定的曲调。程序中采用了INT 21H软中断调用了DOS的常用子程序。-According to different notes in music from the output generated sound waves of different frequencies principle, PC, in 8253 by setting the timer counts different, different tunes by the speaker. The following is to achieve as a PC, can be scheduled to play the piano tunes. INT 21H process using the DOS software interrupt call common routines.

Description: 8253 通道 0 工作在方式 0（脉冲计数产生中断），由按键产生单脉冲接入 CLK0、令计数初值为 0FH，
手动逐个输入单脉冲，编程在计算机屏幕上显示计数值，并用逻辑笔观察 OUT0 的状态，键盘有键按下时
返回 DOS。-8253 channel 0 0 work in way (pulse counting the interrupt), single pulse generated by the key access CLK0, counting the initial value of 0 fh,
Manually enter them one by one single pulse, programming on a computer screen display count value, using logical pen observation OUT0 state, the keyboard has a key press
Returns the DOS.
