File System Interface

LVGL has a File system module to attach memories which can manipulate with files. Here you can find interfaces to

FATFS
PC (Linux and Windows using C standard function .e.g fopen, fread)
POSIX (Linux and Windows using POSIX function .e.g open, read) file systems.

You still need to provide the drivers and libraries, this repo gives "only" the bridge between FATFS/PC/etc and LittlevGL.

Usage

Add these lines to you lv_conf.h:

/*File system interface*/
#define LV_USE_FS_IF	1
#if LV_USE_FS_IF
#  define LV_FS_IF_FATFS    '\0'
#  define LV_FS_IF_PC       '\0'
#  define LV_FS_IF_POSIX    '\0'
#endif  /*LV_USE_FS_IF*/

Enable an interface you need by changing '\0' to letter you want to use for that drive. E.g. 'S' for SD card with FATFS.
Call lv_fs_if_init() to register the enabled interfaces.
