MMC/SD卡以其優(yōu)越的性能,在單片機(jī)嵌入式設(shè)備中得到廣泛應(yīng)用。將MMC/SD卡作為外部掉電存儲(chǔ)介質(zhì)應(yīng)用于音頻信號(hào)發(fā)生器中,通過(guò)8051F330單片機(jī)上的SPI接口,實(shí)現(xiàn)單片機(jī)—MMC/SD卡的存儲(chǔ)擴(kuò)展,設(shè)計(jì)了此硬件平臺(tái)上的MMC/SD卡的單片機(jī)驅(qū)動(dòng)程序,并給出了相應(yīng)的程序代碼,滿足音頻信號(hào)發(fā)生器的大容量存儲(chǔ)要求。
Abstract:
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.
