摘要
介绍了德国Micronas公司生产的CDC3207G微控制器音频模块的原理及应用设计。该音频模块含有脉宽调制单元(PWM),产生由PWM控制的声音方波信号,因此除了生成普通的声音信号,还可产生振幅逐次衰减的锣声信号。
The Audio control solution to the dashboard application based on the Micronas CDC3207G microcontroller is put forward. The audio module includes a pulse-width modulation unit, it can generate sound signal controlled by PWM.For this, besides the normal sound signal, we can also design gong sound with attenuation characteristic.
