lv_img_set_src(MyImage, "http://.." black screen

my mistake - typo , its ok now

LVGL does not support URLs in lv_img_set_src directly. openHASP can load the data into memory first before passing it onto LVGL. This most likely requires PSram because it is very memory intensive.

You can use void hasp_process_obj_attribute(lv_obj_t* obj, const char* attribute, const char* payload, bool update) to pass the parameters to openHASP instead of LVGL. like so:

hasp_process_obj_attribute(MyImage, "src", "http://192.168.0.50/kamera/img/gate.png", true);

Still black

Check the memory, does your board have PSram? Increase the debug level and check the logs, ...

ok, I'll do more tests.

Ps. it works ok from the script

{"page":11,"bg_color":"#000000","comment":"---------- Page 11 Gate ----------"}
{"id":1, "obj":"img","src":"http://192.168.0.50/kamera/img/gate.png","auto_size":1}

doesn't that mean the memory is adequate?
