STM32微控制器(STM32F407VET6) SD-4bits、SD-SPI，FLASH等儲存設備管理

    本實驗開發版使用STM32F4VE，軟體使用STM32CubeIDE與HAL library為開發環境，透過FatFS API同時管理三個SD-4bits,SD-SPI，SPI-FLASH等Devices，SD使用SDIO 4bits與SPI介面兩種方式，另外使用SPI介面存取開發版上的W25Q16JV Flash。

硬體環境： 

開發版上的MicroSD接口使用SDIO SD 4 bits Wide Bus模式，另外使用SPI 2連接外接TFT卡的SD卡，使用SPI1連接W25Q16JV Flash。

實驗內容:

    同時連接三個設備，開發版內接MicroSD為Volume 0，TFT Module上的SD為Volume 1，開發版上的Flash為Volume 2。

    同時mount三個Volumes分別建立檔案，寫入資料，再從Volume0複製image檔到Volume1。

上圖說明Application 透過FatFs Module做檔案操作，FatFs Module透過FatFs MAI(Media Access Interface)與Storage Device Driver對實體設備存取。本實驗著重在MAI實作。SPI SD與Flash Device driver使用上述參考網址2與3。

實驗步驟:

步驟一

    設定SDIO, SPI1, SPI2 Connectivity

• Volume 0:SDIO使用SD 4 bits Wide bus connectivity，開啟相關DMA、NVIC。

使用4bits Wide bus

開啟DMA

NVIC enable

• Volume 1: SPI2(連接TFT卡上的SD，使用SPI mode)

DMA enable

GPIO Pin

PC3為SD_CS

• Volume2: SPI1(連接開發版上W25Q17JV Flash)

GPIO pins

PB0為FLASH_CS

未啟用DMA

步驟二

設定FATFS

• SD Card連接SDIO 4 bits Widw Bus為Volume 0
• User-defined連接SPI 2 SD為Voulme 1
• SPI1 Flash透過手動更改FATF/APP/fatfs.c加入volume2
• Locale and Namespace Parameter:
• USE_LFN:2(使用長檔名)
• LFN_UNICODE:ANSI/OEM(暫時不用中文檔名)
• STRF_ENCODE:UTF-8(可存中文內容)
• Physical Driver Parameter:
• VOLUMES:3(手動改為3，因為要實際連接3個Volumes)
• MAX_SS:4096

修改FATFS/Target/ffconf.h:

#define _FS_LOCK    3  //改為3，因為要同時開啟3個檔案

加入程式碼：

程式堆疊為Application->Fatfs Module->FatFs MAI->Storage Device Controller(Hardware Driver)

• Hardware Driver:
• SD 4 bits Wide bus: bsp_driver_sd.c,bsp_driver_sd.h，STM32CubeIDE已自動產生。
• SD SPI bus: fatfs_sd.c, fatfs_sd.h (參考網址3)
• Flash SPI bus: w25qxx.c w25qxx.h, w25qxxConf.h((參考網址2)
• FatFs MAI:
• 要實作initialize, status, read, write, ioctl
• 透過上面五個functions 呼叫 Hardware Driver實際讀寫資料到device。
• 實作get_fattime取得檔案時間。
• SD 4 bits Wide bus: sd_diskio.c, sd_diskio.h，STM32CubeIDE已自動產生並實作上述functions。
• SD SPI bus:  user_diskio.c, user_diskio.h ，STM32CubeIDE已自動產生，但並未連結。呼叫Hardware Driver參閱下列程式碼一。
• Flash SPI bus: flash_diskio.c, flash_diskio.h參閱下列程式碼二、三。
• 定義每個device的Diskio_drvTypeDef以便呼叫各自的initialize, status, read, write, ioctl functions。SD_Driver(SD 4bits Wide Bus)與USER_Driver(SD SPI)已自動產生，FLASH_Driver參閱程式碼三。
• FATFS/APP/fatfs.c: void MX_FATFS_Init(void)將volume path與 hardware driver連結，修改fatfs.c部分請參閱程式碼四。
• 實驗應用程式main.c請參閱程式碼五。
