In order to realize the control of the transmission frequency of 10 transmission signals and the reception and storage of music type data in a small music broadcasting system, a broadcast control software design scheme based on ATmega16 microcontroller and BH1415F FM chip is proposed, and the debugging simulation method is given. In this scheme, ATmega16 microcontroller is used to receive music type data and frequency control data from I2C master device, and the frequency control data is processed and forwarded to BH1415 FM chip to realize frequency control; the music type data is stored for the voice recording and playback module to control the playback sequence. The debugging simulation and actual application results show that this scheme can correctly control the modulation frequency and efficiently receive and store music type data.
