Description: 1IC网友 做的硬盘MP3资料公开
该播放器使用了美国atmel公司出品的mp3播放器专用芯片at89c51snd1c.
本芯片特性如下：
1)MCS51内核，可以利用单片及开发软件Keil软件方便开发mp3播放器，无需特殊软件平台；
2)MPEG I/II-Layer 3 hardware decoder
.独立MP3 Decoder
.支持48,44.1,32,24,22.05,16khz取样频率
.支持软件31阶音量控制,高中低音均衡控制
.重低音效果
3)集成DAC部件，支持PCM,IIS格式；
4)64K字节片上代码存储空间（100K次擦写寿命）
5)4K字节boot flash memory,USB/UART下载代码
6)集成USB1.1 device部件
7)MMC卡接口
8)IDE/ATAPI接口（HDD/CD-ROM Interface)
9)2通道ADC,8Khz取样-1IC Netizen done disclosing information on the hard drive MP3 player that uses a ATMEL producer of the m p3 players ASIC at89c51snd1c. the chip features are as follows : 1) MCS51 kernel, and can use a single software Keil software development and facilitate the development of MP3 players, without special software platform; 2), MPEG I / II-Layer 3 hardware decoder. De independent MP3 coder. 48,44.1,32,24,22.05 support, ASF sampling frequency. support software volume control 31 bands, high school bass equalization control. bass results 3) DAC integrated components, support PCM, IIS format; 4) 64K-byte on-chip code storage space (100K erase life time) 5) 4K bytes boot Flash h memory, USB / UART download code 6) integrated USB 1.1 device components 7) MMC card interface 8) IDE / ATAPI interfac

这款MP3播放器以at89c51snd1c为核心，以硬盘为存储介质，液晶屏为双行显示，每行显示
7.5个汉字，这块液晶屏以ST7920作为主控制器，内部集成8129个汉字，液晶屏在这个播放器中
用来显示歌曲名称以及一些播放状态
支持FAT16，一个分区，不支持FAT32,
