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.

万年历程序 从1302中读出的数据放在67H（高两位年）66H（低两位年）65H(月）64H（星期）63H（日） 62H(小时)61H（分钟）60H(秒)57H(农历月)56H（农历日） 显示缓冲单元7CH-7BH(4CH-4BH)(年低位),7AH-79H(4AH-49H)月,78H(48H)星期, 77H-76H(47H-46H)日,75H-74H(45H-44H)小时,73H-72H(43H-42H)分钟,71H-70H(41H-40H)秒 5EH-5DH(55H-54H)农历年，5CH-5BH(53H-52H)农历月,5AH-59H(51H-50H)农历日 闰月标志为F0,定时器T1为调整时候闪烁用。 1302在设置调整时间后，要改为禁止写入状态，否则在上电复位的时候就发生误写入，使时间值加1分钟 次程序中的段码表只适用于该特殊的硬件，具体的段码表由具体的硬件决定 -Calendar program read from the 1302 data on the 67H (two-year high) 66H (two-year low) 65H (month) 64H (Week) 63H (date) 62H (hours) 61H (minutes) 60H (second) 57H (Lunar Month) 56H (Lunar date) shows a buffer unit 7CH-7BH (4CH-4BH) (year low), 7AH-79H (4AH-49H) month, 78H (48H) Week, 77H-76H (47H-46H) Day , 75H-74H (45H-44H) hours, 73H-72H (43H-42H) minutes, 71H-70H (41H-40H) second 5EH-5DH (55H-54H) Lunar New Year, 5CH-5BH (53H-52H) Lunar month, 5AH-59H (51H-50H) Lunar Leap Day logo for F0, adjust the timer T1 is used when flashing. 1302 adjust at set time, the status should be cha

单片机产生PWM波对电机进行调速 脉冲宽度调制(Pulse Width Modulation―PWM)是指将输出信号的基本周期固定，通过调整基本周期内工作周期的大小来控制输出功率-Single-chip PWM wave generated on the motor speed Pulse width modulation (Pulse Width Modulation-PWM) refers to the basic cycle of the output signal of a fixed basic cycle by adjusting the duty cycle to control the size of the output power
