# Storage Examples
|
||
|
||
Storage and management of user and system data in module’s 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.
