Modify usbd_stoge_if.c to use SD Card trougth SPI

[ABatt.1]

Hi to all,

I managed to interface with the SD card through the SPI and the FaTFS library (thanks to https://01001000.xyz/2020-08-09-Tutorial-STM32CubeIDE-SD-card/) now I need to implement a USB mass storage device on the same hardware.

i don't know how to modify usbd_stoge_if.c tin odero implement the functions:

int8_t STORAGE_GetCapacity_FS(uint8_t lun, uint32_t *block_num, uint16_t *block_size)

int8_t STORAGE_IsReady_FS(uint8_t lun)

Have you any suggestions?

Thanks.

hello

for the capacity question

 *block_num = hsd.SdCard.BlockNbr ;

 *block_size = hsd.SdCard.BlockSize;

for the second function ,

if device is ready, just return USBD_OK (0)

if not ready , return something else

HI Vangelis,

hsd working for SDIO implementation, with BSP_SD generated from CUbeM.

I'm searcing for a SPI versione of this function.

At the end I was succerfully writed the file.

Here is my usbd_stoge_if.c, writed based on user_diskio_spi.c an user_diskio_spi.h from https://01001000.xyz/2020-08-09-Tutorial-STM32CubeIDE-SD-card/

Thanks.

[PLy.1]

Thanks for your example! I was able to accomplish a similar task for my project thanks to it.

Best regards,
