摘要
为了解决车载MP3系统的实时性、稳定性以及降低成本问题，提出了嵌入式车载MP3系统的软件解决方案．该系统采用了ARM处理器，用带有双路D／A的STM32F103RCT6做主控芯片并且进行MP3的软件解码，内嵌有μC／OS-Ⅱ操作系统，可以播放随身携带的U盘、SD卡等移动设备中的MP3歌曲，并且经过射频模块发射音频信号，通过车内收音机调整频点便可以从车内音响中收听音乐．结果表明，该系统不但实时稳定，而且又降低了产品成本，可以为用户提供优质的音响服务．
This article is to supply a embedded system software solution of car MP3 player for the current real - time, stability and cost issues. This system uses the ARM processor with dual D/A master of STM32F103RCT6 do chips and software for MP3 decoding, embeds μC/OS-Ⅱ operating system, this player can carry the U disk, SD card, and other mobile devices in the MP3 songs, and after launching modules radiofrequeney audio signal through the car radio frequencies can be adjusted from the car to listen to music in stereo. The results showed that the system is not only real-time and stable, but also reduces the product cost, so we can provide users with a high-quality music sorvices.
