SPI Flash Raw APIs Vs using file system operation in SPIFFS
Posted: Wed Apr 24, 2019 4:03 am
- Hi,
- I needed to save the queue data onto flash memory of ESP32, the queue keeps record of incoming data and read each data from front side , process it then that data is deleted from queue. So, can I use spi flash raw APIs like spi_flash_write() , SPI_flash_read() to save data on flash? Or should I maintain a file system on SPIFFS and store my queue into it? Is there some performance effect when we use spi flash raw APIs Vs using file system operation on SPIFFS?
