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。 WebFatFs does not run efficiently on NAND without flash translation layer. Because of the large size of erase sector (128KB is very common these days), a naive port of FatFs on NAND will wear out the first sector (frequent FAT updates) and run dramatically slow (when individual 512 bytes sector are updated by copying a whole 128KB erase block).

If that is cleared out then you let’s go to the SPI initialization. You should initialize SPI as Master with FullDuplex, 8 bits, MSB first, low clock polarity and data transfer on rising edge and that’s all. cpm of circrnas
