[Embeded-SCM Develop] 模拟电子琴

Description: 一、实验目的：（1．由4X4组成16个按钮矩阵，设计成16个音。（2．可随意弹奏想要表达的音乐。二、实验原理（1． 4X4行列式键盘识别；（2．一首音乐是许多不同的音阶组成的，而每个音阶对应着不同的频率，这样我们就可以利用不同的频率的组合，即可构成我们要的所想音乐了，当然对于单片机来产生不同的频率非常方便，我们可以利用单片机的定时/计数器T0来产生这样方波频率信号，因此，我们只要把一首歌曲的音阶对应频率关系弄正确即可音乐产生的方法；若要产生音频脉冲，只要算出某一音频的周期（1/频率），再将此周期除以2，即为半周期的时间。利用定时器计时半周期时间，每当计时终止后就将P1.0反相，然后重复计时再反相。就可在P1.0引脚上得到此频率的脉冲。利用AT89S51的内部定时器使其工作计数器模式下，改变计数值TH0及TL0以产生不同频率的方法产生不同音阶，例如，频率为523Hz，其周期T＝1/523＝1912μs，因此只要令计数器计时1912μs /2/1μs＝956，每计数956次时将I/O反相，就可得到中音DO（523Hz）。计数脉冲值与频率的关系式是： N＝fi÷2÷fr 式中，N是计数值；fi是机器频率（晶体振荡器为12MHz时，其频率为1MHz）；fr是想要产生的频率。其计数初值T的求法如下： T＝65536－N＝65536－fi÷2÷fr 例如：设K＝65536，fi＝1MHz，求低音DO（261Hz）、中音DO（523Hz）、高音DO（1046Hz）的计数值。
