microSD and STM32L476 Discovery kit

Posted by Celine on 2016-02-22 14:31

Hello!

I am currently working on the STM32L476VG Discovery board with the HAL library and I would like to add some memory to save audio files.
For this, I would like to use a microSD card from a IO1 Xplained pro ATMEL board connector.

I have several questions:
- How do I wire both together ? (It looks like the STM32 discovery board is missing a lot of pins such as PC7 ...)
- Do you have any tutorials that explains how to proceed?


Thanks for your reply!

In general you could wire it to one of the SPIs (won’t be superfast htough) it’s available on the same Pins as QUADSPI memory so you lose this functionality... Or just get nucleo

Thanks!

Do you know where I can find any tutorials or project exemples on microSD using SPI bus?

I got it working after a loads of trouble unfrotunatly it’s pretty slow so I would suggest either to interface QuadSPI memory which you have on board already or MicroSD using 4bit SDIO

Thanks for the tutorial, I will take a look at it!

I was thinking of using SPI1 or maybe QuadSPI

Hi!

I decided to go ahead with your FATFS tutorial :-)
They say to modify the “defines.h” to enable SPI for FATFS.
However this file does not exist on the STM32L4 library.
Do you know where it has to be written?
