And, of course, declare the function in fatfs. ly/FatFSinfoIn this video we will explain you how to crea In this video you will learn how to interface a SD-card with FatFS (ExFAT to be exact) using SDIO. Now I try to write data to an SD card, unfortunately so far without success. Let us show you how to add the required libraries and make some modifications in some files which is necessary. Read single lines using FatFS on STM32. The other processor will have access to the SD card not currently in use by the STM32. I can’t write a file to the sd card. c and are the interface used by fatfs. In this example project, our ultimate goal is to test the STM32 SDIO interface with an SD Card and also test the functionalities provided by the FatFS library and use it to create a text file, write to it, read the file, modify the existing file, and This repository contains a working example of STM32L476 FATFS on an SD card using freeRTOS. For this purpose we have modified a SD to Micro-SD adaptor by soldering 9 jumper leads on it (see photo on the right). The card is okay and its already in FAT32 formatted.
