ATMEL AT91SAM USB Mass Storage Module

应用背景STM32 STM32 开发板自带了一颗非常强劲的MP3解码芯 片，利用该芯片我们可以实现 MP3/OGG/WMA/WAV/FLAC/AAC/MIDI等各种音频 文件的播放。关键技术本章实验功能简介：开机先检测字库是否存在，如果检测无问题，则对VS1053进行RAM测试和正弦测试，测试完后开始循环播放SD卡MUSIC文件夹里面的歌曲（必须在SD卡根目录建立一个MUSIC文件夹，并存放歌曲在里面），在TFTLCD上显示歌曲名字、播放时间、歌曲总时间、歌曲总数目、当前歌曲的编号等信息。KEY0用于选择下一曲，KEY2用于选择上一曲，WK_UP和KEY1用来调节音量。DS0还是用于指示程序运行状态，DS1用于指示VS1053正在初始化。

卫星调谐器 DBS TUNER The TA1322FN is a wideband down-converter which can operate at input frequency ranging from 850 MHz to 2200 MHz. Intended primarily for use in satellite tuners, this IC includes an oscillator, a mixer, an IF amplifier and a PLL.-The TA1322FN is a wideband down-converter which can operate at input frequency ranging from 850 MHz to 2200 MHz.
