Abstract
This paper mainly introduces a solution of new digital storage smart car audio system. By using high-efficiency switching power supply, the lower power consumption can be achieved in power-saving mode. The MCU controls the corresponding registers of radio, MP3 decoder and audio processing chip by the I2C bus to implement the digital tuned stereo radio, audio decoding, audio processing functions. In order to achieve the operating memory and continuous playback function of MP3, and the optimization of the user operation and audio-visual experience, the system integrated into the intelligent serf-checking and error correction mechanism.关键词
