Hello all, I am trying to create a SDMMC project for my nucleo L412kb board with stm32cubIDE, but cant find sdmmc component inside my created project. Do I need to add it somehow to my CubIde ?

Is sdmmc it primary component for stm32cubIde or it must be imported manually ? if so please show me where to start.

thanks,

Hakob

Hi @HHako.1​ and and welcome to the Community :),

If you refer to the RM0394 and precisely section 43 "SD/SDIO/MMC card host interface (SDMMC)", you can conclude that the SDMMC is not available on STM32L412 device.

Thank you Kaouthar, what about FATFS+SPI(DMA)->SD ?

As I see these all exist on my board.

FAT FS, And I've confusion

Commands and response are transmitted as 1 bytes to SD card, so if I initialize SPI using DMA by default each 1 bytes commands/response will be exchanged using DMA method, this will have a overhead of initializing the DMA structure each time the commands are send.

I need to make ADC conversion with 400ksps and record them on sd card without delay.

So as I understand I need to order NUCLEO-F746ZG.

Thank you again,
