The code is written in C language, development environment for Keil uv2 or Keil uv3. Code implemented functions are: the nature of the voice conversion into digital code, and then ARM7 data stored in*. mp3 format, SD card, and can playback. The hardware platform is required for NXP' s ARM7 (LPC2478) development board an additional SD card with the file system, is my transplant.

基于ARM7（LPC2478）与SD卡机实现语音回放\语音回放\.plg
