STEVAL-STWINKT1B to read data from accellerometer and write in SD card

Associate II


I bought the STEVAL-STWINKT1B development kit and I used the High Speed Datalog example and setting correctly the JSON in the SD the program works correctly.

I would like to replicate part of the application that is reading the data from the sensors and saving them on the sd without using Freertos.

Currently I am trying to create a file inside the SD but I can't do it,

I tried to open the MX cube program, selected the STEVAL-STWINKT1B board and then I followed the following video

the only thing that I could not replicate was the selection of DMA for SDMMC because there is no DMA tab in SDMMC.

For the rest after following the video and replicated the steps the program compiles but does not save to SD.

How can I solve this problem, thank you in advance.
