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。
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
PC3為SD_CS
- Volume2: SPI1(連接開發版上W25Q17JV Flash)
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。
