摘　　要：MMC/SD卡以其优越的性能,在单片机嵌入式设备中得到广泛应用。将MMC/SD卡作为外部掉电存储介质应用于音频信号发生器中,通过8051F330单片机上的SPI接口,实现单片机—MMC/SD卡的存储扩展,设计了此硬件平台上的MMC/SD卡的单片机驱动程序,并给出了相应的程序代码,满足音频信号发生器的大容量存储要求。MMC/SD card is more and more widely used in the single chip embedded devices for their excellent performances.This article introduces the application of MMC/SD card as the external power down storage medium in audio signal generator. The extension technology especially for storage of single chip-MMC/SD card via SPI interfaces in 8051F330 single chip, including designs single chip drive program of MMC/SD card based on hardware platform,and also gives the key coding of the program. The implementation of big capacity storage is meaningful in audio signal generator.
