本例采用89C52, 晶振为11.0592MHZ，关于如何编制音乐代码, 其实十分简单,各位可以看以下代码.频率常数即音乐术语中的音调,而节拍常数即音乐术语中的多少拍 所以拿出谱子, 试探编吧!-Example use of the 89C52, crystal for 11.0592MHZ, on how to prepare music code, is actually very simple, you can see the following code. Frequency that is constant in terms of tonal music, and the constant beat of music terminology that is how much of the shoot so come up with music score , test made it!
