利用单片机制作音乐播放器的课程设计报告.
作为单片机的重要硬件资源之一，利用定时器可以产生各种固定频率的方波信号，也可以产生包括“Do“、“Re“、“Me“--等音阶在内的各种频率声音。在此设计中我们采用12MHz的晶振，产生的频率信号即音乐信号由P3．7口输出，信号经过放大后由喇叭发出声音。-The use of single-chip production music player curriculum design report. As a single-chip hardware resources an important one, using the timer can generate a variety of fixed-frequency square-wave signal, it can generate, including Do , Re , Me - such as scale, including the voices of various frequencies. In this design we have adopted a 12MHz crystal, resulting in the frequency signal that the music signal from the mouth P3.7 output signal amplified by the horn sounds.
