No SDIO in CubeMX

[DMukh.2]

Good afternoon.

I am using BluePill STM32F103C8T6 board.

I wanted to connect an SD card to it and use it as Mass Storage

​
All examples use the SDIO interface for connection.

But I don't have this item in CubeMX. How can I mount an SD card

This version doesn't have SDIO. See the datasheet table 3 page 13 : https://www.st.com/resource/en/datasheet/stm32f103cb.pdf

Only the 64 or high has SDIO

Btw it depens on your SD card but you may try SPI if possible

I could not find examples where the card is connected via SPI to work in Mass Storage mode

[PieterInHetBos]

What kind of device do you use?

[DMukh.2]

I use the BluePill board on STM32F103C8T6 and a microSd card with a 1G adapter

I want to make mass storage on an SD card for training

You can read up on SD cards and there layout: https://www.electroniccircuitsdesign.com/pinout/sd-microsd-card-pinout.html

D0 can be used as SDO and CMD can be used as SDI, DAT3 is CS.

Please know that datarates are far slower dan SDIO.
