小型广播系统播控端单片机软件设计

Software design for play-controller module in minitype music broadcast system

为了在小型音乐广播系统中实现对10路发射信号传输频点的控制和对音乐类型数据的接收及存储,提出了一种基于ATmega16单片机和BH1415F调频芯片的播控端软件设计方案并给出了调试仿真方法。该方案中采用ATmega16单片机从I2C主设备接收音乐类型数据、频点控制数据,并且将频点控制数据处理后,转发给BH1415调频芯片,实现频点控制;将音乐类型数据存储起来,供语音录放模块控制播放顺序用。调试仿真和实际应用结果表明,本方案可正确控制调制频点,高效接收和存储音乐类型数据。

In order to control I0 frequency points and incept music type data for minitype music broadcast system, software design scheme based on ATmegal6 single chip and BHI415F frequency modulation chip is presented in this paper. And corresponding debugging method is also introduced. The scheme uses ATmegal6 to receive data of frequency point and music type from 12C host equipment. The data of frequency point is transmitted to BH 1415F after process. And the data of music type is saved for record and play module to control play order. The debugging experiment and application show that the scheme can control the frequency point correctly and save the data of music type effectively.
