Design And Realization Of Embedded Car Player

With the rapid development of numeric information technology and network technology,it is brought forward that the automatization and intelligentization of car.The car player will be also reformed as an important part of car.It will be necessary that connect numeric music with car player.Based on these reasons,a scheme of embedded car MP3 player is brought forward.The system is made up of solid-state componet. It can play music with high rate of compression.The user may download music file with MP3,WMA format by USB interface in this embedded system to the flash memory.In this way users may carry out the interlink during car and music in the internet.This paper mainly introduces the designmet of the schematic document and PCB document of hardware circuit .In addition,some operation designment of Flash memory are mainly introduced.Based on the characteristics of Flash memory, the specific designment of Flash file system with high reliability are also introduced.With Flash memory's management have been implemented fine.
