資源簡介

經過了努力，查找了很多資料，終于可以利用STM32的SDIO操作文件系統讀寫了，但是發現為文件命名有問題，要熟悉rt_thread系統的可以上他官網下載說明書，地址:http://www.rt-thread.org/
算是對它的一個宣傳吧。
這里我是修改了下速度擦人sdcard.c里的一些內容使他可以操作我的金士頓4GSD2.0卡。
目前是可以正常操作的，工作在四位總線24MHZ DMA模式。
在這里介紹下經驗，很多操作沒有反應是因為缺少了必要的延時，因為sd卡處理命令也是要時間的，單片機發送命令太快會使得它沒有足夠時間處理，所以我加入了必要的延時，于是就可以正常使用了，但是偶爾還是有些問題的，另外重命名問題我還得上論壇討論下，呵呵。
最后鄙視下那些亂發資源的，明明是官方實例，很多卡都不能初始化就發出來，還有那些網頁亂指導的，我是因為你們的誤導才搞SD搞了一個星期。。強烈BS。。。。
