基于单片机的计算器原程序代码，传上去让大家看看！

这个范例说明如何使用8051 的Port 1连接到四颗七段显示器，PORT 0的低4位分别控制这四颗共阳七段显示器，让四颗共阳七段显示器使用扫描的方式轮流-This example shows how to use the 8051 Port 1 connected to four seven-segment display, PORT 0, low 4, respectively to control the total of four seven-segment display yang, so that a total of four seven-segment display yang way of using the scan rotation

1.电子琴功能 用实验板上K1~K7作为电子琴的7个按键，每个按键对应一个音符要求当按下其中一个按键，就通过P2.5口输出对应频率信号使蜂鸣器发出特定音符声音。 2.乐曲演奏 若按下K8键，完成自动弹奏“送别”歌曲。 -1. Organ function of the experimental board K1 ~ K7 as the organ of the seven buttons, each button corresponds to a note of which require that when the press of a button, on the adoption of P2.5 port output frequency signal corresponding to a specific note to the buzzer sounds . 2. Music playing, if pressed K8 button to complete the auto-play " Farewell" songs.
