使用任意 GPIO 进行映射时,需要注意对时序产生的影响,可参考 “Timing Considerations” 说明。 目前只支持外接 SPI NOR Flash 芯片,以 W25Q32 型号的 SPI NOR Flash 芯片为例,可参见例程 esp-idf/examples/storage/ext_flash_fatfs 1.3 外接 SPI PSRAM 存储外部数据 硬件上支持使用 SPI2 或 SPI3 接口外接 P...
FatFS vs SPIFFS vs NVSby Piramma » Thu Nov 16, 2023 10:08 am Hello, I am trying to have a partition to store large files (upto 600K) and overall partition size allocated can be 1.5-2MB. So, number of files is less, size will be few 100 KBs. While NVS has encryption support...
I'm currently using FATfs components and wear-leaveling. It takes a long time to write them (more than 10minutes). I wonder if SPIFFS could be more quick respect to FATFS or is there a low level method to write in flash directly but we the possibility to use a filesystem to open ...
