WebApr 8, 2024 · STM32文件系统移植FATFS 1.简介 FatFs 是用于小型嵌入式系统的通用 FAT/exFAT 文件系统模块。FatFs 模块是按照 ANSI C (C89) 编写的，与磁盘 I/O 层完全分离。 因此它独立于平台。它可以集成到资源有限的小型微控制器中，例如 8051、PIC、AVR、ARM、Z80、RX 等。 特征 DOS/Windows 兼容 FAT/exFAT 文件系统。 Web使用FatFs进行文件操作之前都使用f_mount函数挂载物理设备，这里我们使用SPI FLASH芯片上的FAT文件系统。 接下来我们直接调用miscellaneous函数进行FatFs设备信息获取、文件定位和格式化写入功能以及目录创建和重命名功能测试。调用file_check函数进行文件信息 …

Developing applications on STM32Cube™ with FatFs

WebMar 10, 2024 · Now the problem is, my microcontroller only have 16 KBytes of RAM. As most of them are occupied by the application, I can give FatFs at most only 1 KBytes. SPI flashes usually have a very large erase unit (e.g W25Q64 is 4 Kbytes size). That's the minimum size that FatFs can operate on the SPI flash. So how do I solve this problem?

It provides a mutable block interface with standard read and write operations. WebJul 23, 2024 · No defragmentation is required to fit large files in, because it is all sector based and there is a chain for each file maintaining which sectors are occupied by it. So the file does not need to be contiguous etc. 2. Erasing Sectors: At the moment when FatFS asks me to write a sector, I always erase it first (just to get things working).
