readme
[](https://components.espressif.com/components/espressif/esp_lv_fs)
## Instructions and Details
`esp_lv_fs` allows LVGL to use filesystems for accessing assets. This component integrates with `esp_mmap_assets` to efficiently manage file operations and supports multiple partitions.
### Features
- Integrates with `esp_mmap_assets` for filesystem creation.
- Supports standard file operations: fopen, fclose, fread, ftell, and fseek.
- Uses the `esp_partition_read` API for efficient file access.
- Supports multiple partitions.
## Add to project
Packages from this repository are uploaded to [Espressif's component service](https://components.espressif.com/).
You can add them to your project via `idf.py add-dependancy`, e.g.
```
idf.py add-dependency esp_lv_fs
```
## Usage
### Dependencies
The [esp_mmap_assets](https://components.espressif.com/components/espressif/esp_mmap_assets) component is required. It provides file offset index relationship.
### Initialization
```c
#include "esp_lv_fs.h"
#include "esp_mmap_assets.h"
esp_lv_fs_handle_t fs_drive_a_handle;
mmap_assets_handle_t mmap_drive_a_handle;
const mmap_assets_config_t asset_cfg = {
.partition_label = "assets_A",
.max_files = MMAP_DRIVE_A_FILES,
.checksum = MMAP_DRIVE_A_CHECKSUM,
.flags = {
.mmap_enable = true,
}
};
mmap_assets_new(&asset_cfg, &mmap_drive_a_handle);
const fs_cfg_t fs_drive_a_cfg = {
.fs_letter = 'A',
.fs_assets = mmap_drive_a_handle,
.fs_nums = MMAP_DRIVE_A_FILES
};
esp_lv_fs_desc_init(&fs_drive_a_cfg, &fs_drive_a_handle); //Initialize this after lvgl starts
```
