Description: SD card controller can just read data using 1 bit SD mode.
I have written this core for NIOS2 CPU, Cyclone, but I think it can works
with other FPGA or CPLD. Better case for this core is SD clock = 20 MHz and
CPU clock = 100 MHz (or in the ratio 1:5). If you have a wish you can achieve this core.

Description: 实现了FATFS+SDHC+SD2.0+SD1.1+Shell+DataFlash。这样功能整合网上绝对没有。大约20 的代码是出自本人。
操作方法：
上电后，发字符串!s0! 进入dataflash shell模式，发字符串close则退出shell模式
发字符串!s1! 进入SD卡shell 模式，发字符串close则退出shell模式
支持MMC(没测试),SD1.0 SD2.0(普通与SDHC)
源码已经在Keil4中运行过，基于STM32F103平台
源码很多是基于网上的资料。感谢各位辛勤的开源大侠。-Achieved FATFS+ SDHC+ SD2.0+ SD1.1+ Shell+ DataFlash. This functional integration is absolutely no line. About 20 of the code is from himself. Operation method: After power-on, hair string! S0! Enter dataflash shell model, made out of shell pattern string close the hair string! S1! Into the SD card shell model, made a string out of shell mode support close the MMC (not test), SD1.0 SD2.0 (ordinary and SDHC) source has been Keil4 run-off, based on STM32F103 source platform is based on a lot of online information. Thank you for the hard open-source heroes.

Description: SD卡有两个可选的通讯协议：SD模式和SPI模式。SD模式是SD卡标准的读写方式，但是在选用SD模式时，往往需要选择带有SD卡控制器接口的MCU，或者必须加入额外的SD卡控制单元以支持SD卡的读写。然而，AT89C52单片机没有集成SD卡控制器接口，若选用SD模式通讯就无形中增加了产品的硬件成本。在SD卡数据读写时间要求不是很严格的情况下，选用SPI模式可以说是一种最佳的解决方案。因为在SPI模式下，通过四条线就可以完成所有的数据交换，并且目前市场上很多MCU都集成有现成的SPI接口电路，采用SPI模式对SD卡进行读写操作可大大简化硬件电路的设计。-There are two optional SD card communication protocols: SD mode and SPI mode. SD model is a standard SD card reading and writing, but in the selection of SD mode, often need to select the SD card controller interface with MCU, or SD card to join the additional control unit to support the SD card reader. However, AT89C52 microcontroller is not integrated SD card controller interface to SD mode if the selected communication would in effect increase the cost of hardware products. The time to read and write data in SD card is not very demanding circumstances, the use SPI mode can say is the best solution. SPI, mode because, by four lines on all the data can be exchanged, and Du Mu Qian Ji Cheng MCU market, there are many existing SPI interface circuit using SPI mode on the SD card reader can be greatly Jianhua Cao Zuo hardware design.

Description: SD卡在现在的日常生活与工作中使用非常广泛，时下已经成为最为通用的数据存储卡。在诸如MP3、数码相机等设备上也都采用SD卡作为其存储设备。SD卡之所以得到如此广泛的使用，是因为它价格低廉、存储容量大、使用方便、通用性与安全性强等优点。既然它有着这么多优点，那么如果将它加入到单片机应用开发系统中来，将使系统变得更加出色。这就要求对SD卡的硬件与读写时序进行研究。对于SD卡的硬件结构，在官方的文档上有很详细的介绍，如SD卡内的存储器结构、存储单元组织方式等内容。要实现对它的读写，最核心的是它的时序，笔者在经过了实际的测试后，使用51单片机成功实现了对SD卡的扇区读写，并对其读写速度进行了评估。-There are two optional SD card communication protocols: SD mode and SPI mode.
