The design of audio player based on P89V52

With the constant improvement of integrated chip design, the miniaturization of devices. The applications range of integrated circuits are more extensive, consumer electronics products are more diverse, which have provided the foundation for development of audio and video. In this paper, a design scheme of audio player will be introduced from on theoretical and practical basis. The audio player uses an MCU of Philips P89V52, a 51 core, and uses SPI mode for transmission of data and clock to perform functions of track selection, volume control, progress display, playback and others. It´s economical and useful.
