Hello guys,

I have a question for :

Question for STM32 USB Full Speed Device Library      V2.2.1

How can I use SD card on Mass_storage demos ?

is it connected via SPI or SDIO ? or I can choose ?

and how can I connect my USB to it ? where can I find the configuration for it ?

I have PA11 and PA12 connected to USB port.

Thanks a lot

Is it possible for me using SPI interface ?

There are opportunities to do it many ways, you'll need to figure out what's appropriate for you, or try some existing boards/solutions to see it work. I would recommend implementing and testing the card reading code independently of USB, and then reintegrate the two.

Tackle the problem in small bites so you don't choke.

so try using SPI then connect via UART as my interface ?

Or just write a test app to exercise the SDCard via SPI, you could output diagnostic information via USART, SWV or LEDs as required.
