基于8051的sd卡驱动程序

适合8051内核单片机的sd卡读写驱动,基于自带SPI模块的单片机AT89S8253修改的.

可以读写单个块或者多个块.

带spi功能的8051单片机应该都不需要修改.

如果要修改只需修改sdconfig.h 和 sdhal.c文件-8051 based on the sd card driver for 8051 MCU core driver sd card reader, based on its own single-chip SPI module AT89S8253 changes. Can read and write single block or multiple blocks. Spi function with the 8051 single- machine should not need to be amended. If you want to modify only files modified sdconfig.h and sdhal.c
