Storage Examples

Storage and management of user and system data in modules flash and on external memory / devices. This directory contains a range of examples ESP-IDF projects. These are intended to demonstrate the storage features, and to provide code that you can copy and adapt into your own projects.

Example Layout

The examples are grouped into sub-directories by category. Each category directory contains one or more example projects:

  • custom_flash_driver example demonstrates how to implement your own flash chip driver by overriding the default driver.
  • emmc example demonstrates how to use an eMMC chip with an ESP device.
  • ext_flash_fatfs example demonstrates how to use FATFS partition with external SPI FLASH chip.
  • fatfsgen example demonstrates how to use FATFS partition
  • nvs_rw_blob example demonstrates how to read and write a single integer value and a blob (binary large object) using NVS to preserve them between ESP module restarts.
  • nvs_rw_value example demonstrates how to read and write a single integer value using NVS.
  • nvs_rw_value_cxx example demonstrates how to read and write a single integer value using NVS (it uses the C++ NVS handle API).
  • partition_api examples demonstrate how to use different partition APIs.
  • parttool example demonstrates common operations the partitions tool allows the user to perform.
  • sd_card examples demonstrate how to use an SD card with an ESP device.
  • semihost_vfs example demonstrates how to use semihosting VFS driver with ESP device.
  • spiffs example demonstrates how to use SPIFFS with ESP device.
  • spiffsgen example demonstrates how to use the SPIFFS image generation tool spiffsgen.py to automatically create a SPIFFS.
  • wear_levelling example demonstrates how to use wear levelling library and FATFS library to store files in a partition inside SPI flash.
