Description
What MCU/Processor/Board and compiler are you using?
Linux, gcc / g++ (mixed, LVLG is compiled with gcc, the main application with g++ and they’re linked with g++)
What LVGL version are you using?
Master. I’m using (a modified version of) the simulator, pulling the master branches for lvgl and lv_drivers and with an updated Makefile to allow for c++ compilation as I’m using libCURL.
What do you want to achieve?
Display an image from the filesystem
What have you tried so far?
In lv_conf.h, I have enabled the STDIO driver and given the letter “S”
#define LV_USE_FS_STDIO 1
#if LV_USE_FS_STDIO
#define LV_FS_STDIO_LETTER 'S' /*Set an upper cased letter on which the drive will accessible (e.g. 'A')*/
#define LV_FS_STDIO_PATH "" /*Set the working directory. File/directory paths will be appended to it.*/
#define LV_FS_STDIO_CACHE_SIZE 0 /*>0 to cache this number of bytes in lv_fs_read()*/
#endif
I’ve tried using the STDIO and POSIX drivers both with the same effect.
Code to reproduce
After lv_init()
I’ve created an image object and set the source with an absolute path:
lv_obj_t * image = lv_img_create(lv_scr_act());
lv_img_set_src(image, "S:/home/phill/Downloads/amigo.jpg");
lv_obj_align(image, LV_ALIGN_CENTER, 0, 0);
lv_obj_set_size(image, 200, 200);
Logs
I’ve enabled logging, and nothing is printed that shows an error, only the creation of the lv_img object.

Any help appreciated!
